In some Polistes wasps, the foundresses build huge nests during the founding phase to improve the thermal condition of these nests. This implies that Polistes wasps change their nesting manner in relation to ambient temperature. To test the hypothesis that nest size increases with latitude, colonies of Polistes chinensis were collected from 11 locations. Three nest parameters, the number of cells cell length and index of functional envelope, increased with latitude. The number of cells at the northernmost station was 60, which was 1.5 times more than in lower latitudes. Cell length increased by approximately 4 mm from low to high latitudes, indicating that extra-building in P. chinensis is remarkable in adding new cells. The number of first broods was not correlated with latitude, whereas the number of second brood increased with latitude because of the numerous cells built at high latitudes.

Some chemical characteristics of oral secretions and larval silk, which contain proteinaceous substances, were analyzed in the nests of four Ropalidia species, R.fasciata, R. taiwana, R. rufocollaris and R. flavopicta, and two Polistes species, P. gigas and P. tenebrkosus. Nitrogen contents in pure oral secretions ranged between 13-14%, and crude protein contents, calculated from the N contents, were 84-89%. The protein content in the larval silk was approximately 90%. The three major amino acids in the nest parts were Gly (23-48%), Ala (16-22%) and Ser (6-19%) in Ropalidia species, and Gly (20-32%), Ser (11-14%) and Pro (10-13%) in Polistes species. These items occupied about 60% of the residues. The three major amino acids in the larval silk were Ala (33-34%), Ser (19-21%) and Glx or Asx (9%). Ala and Ser comprised about half of the residues. In some species, the relative abundance of amino acids in the oral secretions varied depending on the parts of nest, especially in the proportion of GIy. Cluster analyses carried out on the amino acid compositions in the oral secretions generated two distinct groups: One consisted of the nest paper, which contained a small amount of secretion coating and the other consisted of secretion layers of the petiole and secretion membranes made at the bottom of Ropalidia cells. These results suggest a possibility that these wasps can produce oral secretions with different kinds and/or ratios of protein(s) according to their purposes, i.e., construction or maintenance.

The flight activities of the stingless bee Lepidotrigona hoozana and honeybee Apis cerana were studied diurnally and periodically to examine temporal and climactic foraging niche differentiation in Taiwan. Statistical analyses showed that the level of flight was correlated with the temperature and light intensity in both species. Both species could fly under dry and moderately wet conditions. We conducted a principle components analysis (PCA) to tease apart the effects of different environmental variables. The first PCA factor for L. hoozana was temperature limits on flights and foraging. For A. cerana, the PCA revealed that light intensity was the most important limiting factor. In most cases, A. cerana foragers had more departure flights per unit time and spent more time flying than foragers of L. hoozana. The minimum flight temperatures for L. hoozana ranged from 11°C to 16 °C, and were higher than the minimum flight temperatures of 8 °C to 10 °C for A. cerana. Thus, A. cerana colonies exhibited greater flight activity during cooler times of the year than L. hoozana. This was more of a benefit in A. cerana than L. hoozana because of the physiological predominance.

Neotropical Entomology

Polybia scutellaris (White) builds large nests characterized by numerous spiny projections on the surface. In order to determine whether or not the nest temperature is maintained because of homeothermic conditions of the nest individuals or otherwise, we investigated the thermal conditions within the nests built by P. scutellaris. We measured the temperature within active and abandoned nests. The temperature in the active nest was almost stable at 27°C during data collection, whereas the temperature in the abandoned nest varied with changes in ambient temperature. These results suggest that nest temperature was maintained by the thermogenesis of the individuals of the colony. This is the first report of nest incubation caused by thermogenesis of species of Polybia wasps.

Six Ctenoplectra species are recorded from Southeast Asia and Taiwan. They are C. chalybea Smith, C. cornuta Gribodo, C. davidi Vachal, C. elsei Engel, C. sandakana sp. nov. and C. vagans Cockerell. Females of C. sandakana sp. nov. from North Borneo are similar to the mainland species C. chalybea, but differ mainly in the clypeal keel and the length of the antennal segments. The small blackish species, C. cornuta, is distributed in Myanmar, China and Taiwan and C. davidi is distributed in China, Russia and Taiwan; both species are seen at the flowers of Thladiantha. Ctenoplectra chalybea was collected from the Malay Peninsula, Myanmar, Taiwan and Vietnam. Ctenoplectra apicalis Smith and C. kelloggi Cockerell are allied to C. chalybea; however, C. kelloggi is excluded from this study due to insufficient material. A key to the six known Ctenoplectra species is given. The large metallic species, C. chalybea and C. elsei, visit flowers of Momordica cochinchinensis (Lour.) Spreng. For the first time observations on the nest structures of C. chalybea and C. cornuta are presented. They choose remarkable places, such as artificial structures and buildings, for nest sites. The nest architecture prevents rain and direct sunlight from entering the nest. Bees used pre-existing holes or crevices in wood for nesting shelters and collected soil and appeared to mix it with some other substance to build nests. The cell lining materials and rubbing behaviors against the cell wall suggest that Ctenoplectra bees use floral oil mainly for cell lining materials.

The thermal characteristics of a colony of Apoica flavissima, an epiponine wasp, were examined. The nest, with a diameter of slightly less than 30 cm, was built on a twig of an orange tree. The temperature of the roof surface fluctuated greatly, ranging between 19.1 and 41.5°C. However, the temperature in the central cell was kept constant at around 27°C throughout a day. Although heavy rain pelted the nest roof in the morning, the central cell maintained temperatures higher than 25°C. On the contrary, after all immature and adult wasps were removed the temperature in the nest fluctuated considerably. The presence of immature individuals and adult wasps densely covering the under surface of the comb seemed to function as an effective insulator. The smaller temperature fluctuation in the central cell than on the roof surface, when the nest was in the empty state, suggests that the thick spongy tissue of the roof made from curled plant leaf hairs serves as an insulator to prevent the conduction of solar heat into the cells and the outward flow of heat generated in cells, especially at night.

The thermal characteristics of mud nests of Polybia spinifex were investigated by measuring internal and surface temperatures of the nests. The nests had a layer of mud envelope and consisted of mud with fine sand particles. The envelope had a vertically long slit-like entrance hole. The mud nests had high thermal conductivities (0.51–0.56 W/(m°C)) comparable to brick, rather than insulation materials of wasps' nests such as paper and wood. It was revealed that the long entrance radiated more heat from the thermo-image. The rate of thermal radiation (emissivity) of the nest surface was 0.80, and the value was similar to that of sand. The internal temperatures of the nests were high from top (T n1 , temperature difference between ambient temperature (T a) was 10°C) to bottom (T n3 , difference, 5°C) at noon. On the other hand, the temperature distributions were reversed during the night. Temperature T n1 was lower by 1°C than T a , possibly from nightly dew on the top surface, whereas, at the middle point (T n2) and T n3 , temperatures were higher by 1°C compared to T a. Temperature fluctuations (ranges between maximum and minimum temperature) at T n2 and T n3 were similar to that of T a , whereas the values at T n1 and T s were higher than that of T a .

Temperatures in 3 natural nests of the Taiwanese stingless bee Trigona (Lepidotrigona) ventralis hoozana were measured in Dapu and Tsaoshan, Chiayi County, Taiwan from Dec. 2002 to Mar. 2004. The temperature in the brood rearing zone of 2 nests was kept relatively constant in a range of 29-32°C. Even in the morning in Jan., the temperature in the brood area was maintained at 29.5°C, about 21°C higher than the ambient temperature. Healthy nests could tolerate ambient temperatures even lower than 8°C, judging from the elevational distribution limit of this species and corresponding meteorological records. The maintenance of constant temperatures in the brood area is chiefly due to ameliorated thermal conditions in the nesting cavity. This is realized by the thermostatic effect of the thick wood of the living tree enclosing the cavity. The involucrum, which completely encloses the brood combs, may retain thermal energy generated by the adults and partially by the mass of brood in the brood area.

A paper wasp that dwells in cold regions, Polistes riparius, shows a behavioral habit of building empty cells around the brood-rearing areas and elongating cells up to twice as long as the body length of pupae. We investigated the thermal effect of the number and the length of cells by using model nests with various numbers and lengths of cells. The relationship between the position of the brood-rearing area and temperature distribution in the comb was also studied in relation to the height of the nest from the ground. When the models were heated from above, the cell temperature was high in the model with a greater number of cells or longer cells. Elongated cells appeared to effectively protect against the wind when the thermal effect of the number and the length of cells was compared. When a specific-size model was heated from below and above along with changing the distance from the floor, the temperature distribution was consistent with a change in the height from the floor, and the temperature distribution was consistent with the position of the brood-rearing area and the height of the model nest from the floor. Finally, we compared the thermoregulation of nests between P. riparius and P. biglumis, which also dwells in cold regions and builds extra cells, and it was concluded that these nesting habits are related to thermoregulation of brood-rearing areas and serve as adaptive measures in cold regions.

... Higher humidity can trigger nectar secretion in flowers, increasing foraging to access this reward despite a less-than-optimal environment (Willmer, 1983). Many studies contradict our findings on the relationship between relative humidity and bee foraging activity (Corbet, 1990;Sung et al., 2011;Alves et al., 2015) and pointing direct and indirect effects on the bees (Corbet, 1990). Directly, the flight can be difficult for bees under humid conditions, and pollen collection can also be problematic, as pollen grains can fail to adhere to a humid body because of an electrostatic charge, which makes it difficult for the corbiculated bees to pack moist loads of pollen (Corbet, 1990). ...

... The use of mud for nest construction has an ecological advantage in that the hard mud nest is more resistant to destruction by vertebrate predators (O'Donnell and Jeanne 2002) and heavy rains (Richards 1978) than the paper nest. In the mud nests, the thermal conductivity (0.69 W/(m°C)) is much higher than those of paper nests (Hozumi et al. 2009); a paper envelope of a vespine nest is 0.08-0.20 W/(m°C) (Schmolz et al. 2000). ...

... Las reinas de muchos véspidos sociales, una vez apareadas, pasan la parte meteorológicamente adversa del año, coincidente con los primeros meses de su vida adulta, refugiadas en algún espacio que las proteja de las inclemencias del tiempo, y el azar dicta que a veces el refugio sea algún objeto que los medios de transporte humanos llevan luego, inadvertidamente, lejos del punto de origen. Esto trae como consecuencia, especialmente en los últimos tiempos, caracterizados por un enorme auge del transporte de mercancías y viajeros, que con cierta frecuencia se introduzca alguna especie de véspido fuera de su área nativa (Beggs et al., 2011;Castro et al., 2013), y concretamente dentro de los Vespinae se van acumulando ya un cierto número de introducciones; muchas veces éstas no desembocan en el asentamiento del véspido, como en el caso de Vespa orientalis Linnaeus, 1771 en Méjico (Dvořák , 2006) y Valencia, en España (Hernández et al., 2013), o el de Vespa simillima Smith, 1868 en Canadá (Kimsey & Carpenter, 2012) y Taiwán (Sung et al., 2006(Sung et al., y 2014, pero en ocasiones sí que han llevado al establecimiento de poblaciones en los países de acogida, por ejemplo con Vespa crabro Linnaeus, 1758 en Norteamérica (Archer, 2012), Vespa velutina Lepeletier, 1836 en Europa, Corea y Japón (Mazzei et al., 2018;Takeuchi et al., 2017) o Vespula germanica (Fabricius, 1793) en el Cono Sur de Sudamérica, Sudáfrica, Norteamérica, Australia, Nueva Zelanda y otros territorios insulares (Carpenter & Kojima, 1997). De los vespinos asentados en áreas no nativas, algunos (por ejemplo V. crabro en Norteamérica) no parecen tener un impacto grave en los territorios colonizados (Beggs et al., 2011), mientras que otros, como V. velutina en Europa y V. germanica en Nueva Zelanda, han evolucionado hasta la categoría de especies invasoras (el Convenio sobre la Diversidad Biológica (Secretariat of the Convention on Biological Diversity, 2019) define "especies invasoras" como aquellas "cuya introducción y/o diseminación fuera de su distribución natural, pasada o presente, constituye una amenaza para la diversidad biológica"). ...

A new record of a hornet (Hymenoptera: Vespidae) from Taiwan

... In the stingless bees (Apidae, Meliponini), a group of highly eusocial of bees from Neotropical, Afrotropical and Australasian regions (Camargo and Pedro 2013;Grüter 2020), nest climate regulation has been considered primarily a function of passive mechanisms, such as nesting location and/ or nest morphology (Jones and Oldroyd 2007). For many ground-or tree-nesting Meliponini, the selection of an appropriate cavity has been proposed to be the principal mechanism for keeping nest temperatures within an optimal range, despite sometimes large variations of ambient temperatures (Moritz and Crewe 1988;Sung et al. 2008;Torres et al. 2009;Zucchi and Sakagami 1972). In addition to the thermic insulation provided by the material surrounding the cavity, several stingless bee species envelop their brood-combs with multiple thin layers of cerumen, the involucrum, which has been suggested to conserve the temperature in the brood area (Engels et al. 1995;Fletcher and Crewe 1981;Roubik and Peralta 1983;Sung et al. 2008;Torres et al. 2007;Zucchi and Sakagami 1972). ...

The independent-founding Polistinae apply an "ant repellent" from their van der Vecht's gland to the pedicel of their nest (Dani et al. 1996; Espelie and Hermann 1990;Evans and Eberhard 1970; and rubbing activity appears to become more common when ants are present (Post and Jeanne 1981;). However, Kudo and Yamane (1996) found that pedicel rubbing behavior occurs in Polistes wasps even when ants are not present and it occurs at rates similar to those occurring in wild specimens from the same latitude where the lab wasps were obtained, suggesting that there is an inherited latitudinal effect on this behavior. Parapolybia indica foundresses rub the pedicel in close temporal association with departure from the nest and this association is more frequent prior to emergence of workers than after workers have emerged and are able to defend the nest while foragers were off of the nest . ...
