Article
Parasitic mites have thus far been recorded only rarely from vespine wasps. We found larvae of the erythraeid mite Charletonia southcotti feeding on hornets, mainly Vespa analis workers that had been collected with bait traps. The mite seemed to prefer hornets stylopized by Xenos spp. as hosts to non-stylopized individuals, since in collections mad...
Article
Ticks are obligate blood feeders that parasitize a variety of vertebrates and can be serious pests for these animals. Due to public concerns about the risk of chemical controls, there is a high demand for biological control agents to reduce tick populations and the spread of tick-borne diseases. In this study, we observed tick predation by the pseu...

Social wasps, which are important agents of ecosystem services (as predators) and disservices (as stinging pests),were collected with Malaise traps in Japanese cedar (Cryptomeria japonica) plantations in three regions of Japan (Tohoku, Shikoku, and Kyushu). Each region had 12 study stands that were categorized into the following four types based on...
Article
Ovary contents and insemination status were examined in overwintered queens of Vespa mandarinia that were collected using bait traps in Ibaraki Prefecture, eastern Japan. Catches in the traps occurred from late April to early July in 1999, though they were few or rather sporadic in and after June. Fertilization rates were 100% in 1999, and 93% in 1...
Article
We constructed a hazard map for oak wilt disease in Yamagata and Fukushima Prefectures, Japan, based on a logistic regression model. Within the framework of a regression model, we incorporated data from previously damaged areas on vegetation type, geography and meteorology, and pest immigration. We evaluated the predictive power of the model using...
Article
We investigated the concentrations of radiocesium in epigeic earthworms, litter, and soil samples collected from forests in Fukushima Prefecture 6 months after the Fukushima Dai-ichi Nuclear Power Plant accident in 2011. Radiocesium concentrations in litter accumulated on the forest floor were higher than those in the soil (0-5 cm depth). The highe...

The nematode Sphaerularia vespae only parasitizes hornet queens and deprives them of fertility. To elucidate its transmission route, we observed the behavior of overwintered queens of Vespa simillima found around decayed logs of fallen trees—the principal hibernation sites for this species. We found that overwintered queens frequently visited those...

The community structures of Mesostigmata, Prostigmata, and Oribatida in the soil of broad-leaved regeneration forests and conifer plantations of various ages were assessed alongside soil and plant environmental variables using three response metrics (density, species richness, and species-abundance distribution). The density and species richness of...
Article
Since the 1960s, Japan has become highly dependent on foreign countries for natural resources, and the amount of managed lands (e.g. coppice, grassland, and agricultural field) has declined. Due to infrequent natural and human disturbance, early-successional species are now declining in Japan. Here we surveyed bees, birds, and plants in four human-...
Article
Although primary forests are important for biological conservation, the value of secondary forests for forest-dependent organisms needs to be evaluated when habitat restoration is required. We examined whether flower-visiting insects can use secondary forests as alternative habitats to primary forests. In particular, we compared assemblages of bees...
Article
In a mutualistic relation between a potter wasp, Allodynerus delphinalis (Giraud) (Hymenoptera: Vespidae), and its specific parasitic mite, Ensliniella parasitica Vitzthum (Winterschmidtiidae), behaviour of the mite guarding the wasp and attacking their common natural enemy, Melittobia acasta (Walker) (Hymenoptera: Eulophidae), was examined.While m...

In this study, the influence of individual cuticular hydrocarbons on nestmate recognition in Japanese hornets was investigated. Cuticular hydrocarbons were extracted from the individuals of several colonies of Japanese hornets, Vespa analis Fablicius (Hymenoptera: Vespidae), and analyzed by combined gas chromatography and mass spectrometry (GC-MS)....
Article
The alien predatory lizard, Anolis carolinensis, has reduced the insect fauna on the two main islands of the Ogasawara archipelago in Japan. As a result of this disturbance, introduced honeybees are now the dominant visitors to flowers instead of endemic bees on these islands. On the other hand, satellite islands not invaded by alien anoles have re...

Abstract Tube-nesting bees and wasps were collected with bamboo tube nest traps in a cherry blossom forest and an old secondary forest in Tama Forest Science Garden in the western suburbs of Tokyo. Curtain type traps, in which bamboo tubes were vertically arranged, attracted more bees and wasps to nests than bundle type traps, in which bamboo tubes...
Article
This is the first record of Xenos moutoni, a specialized parasite of hornets (Vespa spp.), in Korea. Among six Vespa species collected with bait traps in Andong, central South Korea, approximately 10% of female Vespa analis (gynes plus workers) were parasitized, whereas the other five species (V. crabro, V. mandarinia, V. simillima, V. ducalis, and...
Article
1. In large-scale field surveys, a binary recording of each species’ detection or nondetection has been increasingly adopted for its simplicity and low cost. Because of the importance of abundance in many studies, it is desirable to obtain inferences about abundance at species-, functional group-, and community-levels from such binary data. 2. We d...
Article
Crop pollination is an essential ecosystem service, which, when provided by wild pollinator species, can be negatively affected by human activities at a landscape scale. Various pollinator species can be affected by landscape factors and/or act at different spatial scales. We investigated whether different landscape factors at different spatial sca...

Gastral rubbing on the nest pedicel by a Vespa analis founding queen is described based on observations conducted on a pre-emergence nest. The foundress turned around the pedicel, rubbing the pedicel with her gastral tip. This behavior is very similar to that reported in Polistes or other polistine genera, in which females apply ant repellents prod...
Article
Crop pollination by animals is an essential ecosystem service. Among animal-pollinated crops, distylous plants strongly depend on animal pollination. In distylous pollination systems, pollinator species are usually limited, although flowers of some distylous plants are visited by diverse animals. We studied the pollination biology of common buckwhe...

Some bees and wasps that host mites have peculiar pocket-like structures called acarinaria. These have long been considered as morphological adaptations to securely transfer beneficial mites into nests, and thus are thought to be the product of a mutualistic relationship. However, there has been little compelling evidence to support this hypothesis...
Article
Natural vegetation is often replaced by invasive alien plants on isolated oceanic islands. To determine how invasive alien plants affect insect diversity, we compared flying insects captured using Malaise traps among different vegetation types on a small island (Nishijima; 0.49 km2) in the oceanic Ogasawara (Bonin) Islands in the north-western Paci...
