| new tachinidae (diptera) host records of eastern north american forest canopy lepidoptera: baseline data in a bacillus thuriengiensis variety kurstaki nontarget study. | macrolepidopteran caterpillars collected in 1995 and 1996 in the monongahela national forest, pocahontas county, wv, and the george washington national forest, augusta county, va, yielded 60 previously unreported tachinid host associations. most associations were between native species, but the introduced polyphagous tachinid compsilura concinnata (meigen) produced eight new associations with native hosts. the tachinids collected were slightly broader in their host preferences than associated br ... | 2001 | 11681675 |
| evaluation of oils and microbial pathogens for control of lepidopteran pests of sweet corn in new england. | vegetable and mineral oil, beauveria bassiana (balsamo) and bacillus thuringiensis subsp. kurstaki berliner were evaluated for control of ostrinia nubilalis (hübner) (lepidoptera: pyralidae), helicoverpa zea (boddie) (lepidoptera: noctuidae) and spodoptera frugiperda (j. e. smith) (lepidoptera: noctuidae) in sweet corn (zea mays l.). field experiments in maine and massachusetts during 1993 and 1994 evaluated oils and pathogens singly or in combinations, using a single application directly to the ... | 2003 | 14977100 |
| a survey of hymenopteran parasitoids of forest macrolepidoptera in the central appalachians. | in 1995 and 1996, we conducted a study of the hymenopteran parasitoids of macrolepidopteran larvae in the george washington national forest (gwnf), augusta county, virginia, and the monongahela national forest (mnf), pocahontas county, west virginia. macrolepidopteran larvae were collected from canopy foliage and from under canvas bands placed around tree boles. a total of 115 macrolepidopteran species and 5,235 individual larvae were reared. forty-two percent (2,221) of the larvae were gypsy mo ... | 2004 | 15154467 |
