Biological Control of Tortricidae in Tea Fields in Japan Using Insect Viruses and Parasitoids

Tea is a perennial and evergreen plant. Cultivated tea trees provide a habitat for insect pests and their natural enemies. In Japan, granuloviruses (GVs) have successfully controlled two of the most important pests of tea, Adoxophyes honmai and Homona magnanima (Tortricidae: Lepidoptera). The GVs are produced in vivo and a single application sustains pesticidal efficacy throughout a year, which encompasses 4 to 5 discrete generations of both species. A. honmai and H. magnanima also have various natural enemies, especially hymenopteran parasitoids. Such resident natural enemies also play a role in reducing the pest density in virus-controlled fields, but the effect of virus infection on parasitoids sharing the same host larva has not been well studied. Survival of one of the major parasitoids of A. honmai, Ascogaster reticulata (Braconidae: Hymenoptera), is reduced by virus infection of the host. Viruses, including GV and entomopoxvirus (EPV), and certain koinobiont endoparasitoids, including A. reticulata, are both known to regulate host endocrinology. However, the GV and EPV have distinct host regulation mechanisms, and consequently have different impacts on the survival of A. retuculata, when A. reticulata parasitizes a host that is infected with either GV or EPV. These additional effects on host regulation displayed by both viruses and parasitoids affect the outcome of virus-parasitoid interactions.

Responses of 9 lepidopteran species to Bacillus thuringiensis： How useful is phylogenetic relatedness for selecting surrogate species for nontarget arthropod risk assessment？

To evaluate phylogenetic relatedness as a proxy for susceptibility to Bacillus thuringiensis （Bt） when selecting species to act as surrogates for others in prerelease test- ing, we examined the responses of 11 laboratory-reared lepidopteran colonies, comprising members of 2 families, 5 genera, and 9 species, to a commercial Bt preparation. Sur- vival, pupal mass, and timing of pupation and adult emergence of 2 noctuids （Spodoptera litura and Helicoverpa armigera） and 7 tortricids （Cnephasia jactatana, Ctenopseustis obliquana, Ctenopseustis herana, Planotortrix octo, Planotortrix notophaea, Planotor- trix excessana [2 different laboratory colonies], and Epiphyas postvittana [2 colonies]） were examined after feeding first instar larvae with artificial diet containing 5 μL/100 mL Dipel ES （Bt subsp, kurstaki）. Bt caused significant larval mortality in all species except S. litura, in which only pupation was delayed compared with untreated controls. Neither of the noctuid species tested would act as a suitable surrogate for the other in tests of Bt impacts on survival. With the exception of the 2 colonies orE. postvittana, which differed from each other not only in their responses to Bt but also in their development times when not treated with Bt, species within each tortricid genus had similar responses to Bt and thus could act as surrogates for each other. Members of different genera within this family could represent each other only if relatively coarse measurement endpoints （e.g., toxic or not） were considered adequate for assessing risks to nontarget species in the field.
