Article: Seasonal abundance and synchrony between Laricobius osakensis (Coleoptera: Derodontidae) and its prey, Adelges tsugae (Hemiptera: Adelgidae), in Japan[show abstract] [hide abstract]
ABSTRACT: Laricobius osakensis Montgomery & Shiyake, native to Japan, is being measured as a potential biological control agent of the hemlock woolly adelgid, Adelges tsugae Annand, in the eastern United States. Adelges tsugae, a destructive pest threatening the hemlock ecosystems in the eastern United States, was introduced from Japan. This is the first detailed study of the life history of L. osakensis, A. tsugae, and their interaction in Japan. The seasonal abundance of L. osakensis and A. tsugae was assessed in a field study conducted from December of 2007 to November of 2008 in Hyogo, Nara, and Osaka Prefectures (Japan). The sistentes generation of A. tsugae in Japan matured 2 mo later than that reported in British Columbia, Canada, but 1 and 2 mo earlier than in Virginia and in Connecticut, respectively. Timing of the sexuparae generation occurrence in Japan was similar to that observed in Connecticut and Virginia, but this generation has not been observed in British Columbia. Phenological differences among the various A. tsugae population in the eastern U.S. states and Japan can be explained by temperature differences at the locations. Aestival diapause of the predator L. osakensis coincided with diapausing first-instar A. tsugae sistentes. The start of L. osakensis adult activity, oviposition, and larval development was synchronized closely with sistentes development resumption, sistentes adults close to oviposition, and sistentes adults with eggs, respectively. These results indicate good synchrony between L. osakensis and suitable prey stages of A. tsugae in the native habitat of both species.Annals of the Entomological Society of America 03/2013; 106(2):249-257.

Article: High viral load in the planthopper vector Delphacodes kuscheli (Hemiptera: Delphacidae) is associated with successful transmission of Mal de Río Cuarto virus[show abstract] [hide abstract]
ABSTRACT: Delphacodes kuscheli Fennah (Hemiptera: Delphacidae) is the main natural vector of Mal de Rõ´o Cuarto virus (family Reoviridae, genus Fijivirus,MRCV),which infects different gramineae and causes the most important maize (Zea mays L.) disease in Argentina. MRCVÐvector interactions usually are studied using different winter cereals as hosts. Under experimental conditions, �50% of D. kuscheli planthoppers fed on a MRCV-infected plant can transmit the virus to wheat (Triticum aestivum L.). This fact is inßuenced by insect development stage at acquisition and the latency period. This work describes the relation between transmission efÞciency and MRCV accumulation in its planthopper vector. First- and third-instarD. kuscheli nymphs were allowed to feed on MRCV-infected plants, and 9 or 17 d after the acquisition access period (AAP), viral load of transmitting and nontransmitting planthoppers was quantiÞed by quantitative polymerase chain reaction. The transmitting planthoppers showed signiÞcantly higher viral titers than nontransmitting ones, suggesting that successful transmission is positively associated to viral accumulation in the insect. However, planthoppers of the third-instars group did not transmit the virus 9 d after AAP, even when 46% had similar titers to the transmitting insects of the other treatments. These results indicate that additional factors inßuence MRCV transmission efÞciency when acquisition occurs in older planthoppers. This is the Þrst precise quantitative analysis of MRCV in its main vector species and will deÞnitely contribute to better understand planthopperÐFijivirus interactions and its epidemiological implications.Annals of the Entomological Society of America 01/2013; 106(1):93-99.
Article: Five New Records of Drosophilids (Diptera) in a Riparian Forest in the Brazilian Savanna, an Endangered Neotropical Biome[show abstract] [hide abstract]
ABSTRACT: Although drosophilids are widespread models in genetics and molecular biology, their diversity and distribution is relatively poorly known. Field information is important because it provides an appropriate framework to interpret genetic and evolutionary studies. We sampled drosophilids in the Brazilian savanna, one of 34 biodiversity hot spots worldwide. This extremely rich and endangered biome is highly seasonal and consists of a vegetation mosaic, ranging from open Þelds to riparian forests; these forests occupy only 5% of the Brazilian savanna but concentrate most of the biomeÕs diversity. Twelve monthly collections in a riparian forest of the Brazilian savanna revealed 61 drosophilid species, comprising the genera Amiota Loew, Drosophila Falle´ n, Neotanygastrella Duda, Rhinoleucophenga Hendel, Scaptodrosophila Duda, Zaprionus Coquillett, and Zygothrica Wiedemann. This richness represents about a half of the recorded drosophilid species of the whole biome, and includes Þve new occurrences for the Brazilian savanna: the genus Amiota, Drosophila coffeata Williston, D. neorepleta Patterson and Wheeler, D. pseudosaltans Magalha˜es, and Rhinoleucophenga brasiliensis (Lima). This result suggests that drosophilid richness in this biome is likely to be high but remains understudied.Annals of the Entomological Society of America 01/2013; 106(1):117-121.

ABSTRACT: Demotispa neivai Bondar (Coleoptera: Chrysomelidae) can damage the surface of oil palm fruits in Colombia. This specie has also been reported in Arecaceae species but without clarity on its identity. The aim of this study was the redescription of D. neivai using diagnostic characters. The external morphology of the insect body was described with scanning electron microscopy and its sexual dimorphism analyzed by morphometric data on width of the body, length of antennae, scutellum, and legs. The body of D. neivai is observed reddishÐbrown or slightly reddishÐyellow, oval shape, dorsally ßattened, and convex laterally; small head; maxillary palps with segments nearly similar in length; bases of the antenna separated by a keel in the front; compound eyes slightly protruding; pronotum with curved lateral margins; scutellum pentagonal; elytra oval covering almost the entire abdomen; with four sternites visible. The head antennae, body width, hindlegs, elytra, pronotum, and abdomen are the best structures to characterize the sex dimorphism of D. neivai. Additionally, differences and similarities with other phytophagous chrysomelid species of oil palm and were discussed.Annals of the Entomological Society of America 01/2013; 106(2):164-169.
Article: Temperature-Dependent Development and Cold Tolerance of Microtheca ochroloma (Coleoptera: Chrysomelidae), a Pest of Cruciferous Crops in the Southeastern United States[show abstract] [hide abstract]
ABSTRACT: The yellowmargined leaf beetle, Microthecaochroloma (Stål) (Coleoptera: Chrysomelidae ), is an adventive pest of cruciferous crops in the southeastern United States. Despite its pest status, there is limited information about the infiuence of temperature on development and survival of M. ochroloma. The objectives of this study were to assess the effect of temperature on the development and survival of immature stages, and determine the cold tolerance of immature and adult stages. Development was evaluated at 15,20, 25, and 30°C, and cold tolerance was measured at 5,0, and -5°C inside environmentally controlled chambers. Survival of M. ochroloma from egg to adult was ≈80% at 15,20, and 25°C, but only 24% at 30°C. Mean developmental time was longest at 15°C (57 d) and shortest at 30°C (17 d). Leaf area consumed by the fourth instar was 7.4-fold lower at 30°C compared with consumption at 15, 20, or 25°C. The lower developmental threshold varied from 7.3 to 9.8°C and the total degree-days required to complete development from egg to adult was 333. At 5,0, and -5°C, the LT90 values for the first instar were shorter compared with all other stadia, suggesting that the first instar is the most susceptible to cold temperatures. Eggs were most cold tolerant, followed by pupae and adults. Based on the LT50 (13d) andLT90 (38d) of eggs at 0°C, the predicted northern distribution of M. ochroloma extends to Kansas, Illinois, Kentucky, and Virginia.Annals of the Entomological Society of America 11/2012; 105(6):859-864.
Article: Geographically Based Diversity in Mitochondrial DNA of North American Lygus lineolaris (Hemiptera: Miridae)[show abstract] [hide abstract]
ABSTRACT: The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), is a highly polyphagous insect pest. It is the most widely distributed Lygus species in North America, and it is the most prevalent member of the genus Lygus in the eastern half of the continent. We sampled multiple populations of L. lineolaris from three disparate regions of North America, and used parts of the mitochondrial genes cytochrome oxidase 1 and cytochrome oxidase 2 as markers to assess intraspeciÞc diversity of this species. Results indicated that there is an association between genetic population structure and geography. Neighbor-joining, maximum parsimony, Bayesian inference analysis, and maximum likelihood trees suggested that most L. lineolaris individuals belong to two closely related clades showing sympatric distribution. MitochondrialDNAhaplotypes common to widely dispersed populations were observed. Morphological identities of Þve L. lineolaris samples that formed an outlier clade indicated incongruence between morphological identity and genetic data. Individuals from the two major clades and one disparate clade did not exhibit recognizable morphological differences. No strong host plant associations were observed among clades, thus, genetic structuring in this species appears to mostly be geographically based. This study represents the Þrst attempt to survey cytochrome oxidase 1 and cytochrome oxidase 2 variation within L. lineolaris and to use those genes to construct a molecular phylogeny for this species.Annals of the Entomological Society of America 11/2012; 105(6):917-929.
