effects of three nutritional levels of beet root molasses, cheese permeate, wheat bran extract, rice bran extract and sabouraud,s dextrose broth (sdb) were evaluated for blastospore production by two isolates of beauveria bassiana sensu lato. at an interval of 24 h for seven days. depending on the isolate, maximum blastospore production was obtained in 12% rice bran extract and 20% cheese perme...

Current anticholinesterase pesticides were developed during World War II and are toxic to mammals because they target a catalytic serine residue of acetylcholinesterases (AChEs) in insects and in mammals. A sequence analysis of AChEs from 73 species and a three-dimensional model of a malaria-carrying mosquito (Anopheles gambiae) AChE (AgAChE) reported here show that C286 and R339 of AgAChE are ...

Etoxazole, 2-(2,6-difluorophenyl-4-[4-(1,1-dimethylethyl)-2-ethoxy-phenyl]-4,5-dihydrooxazole, an organofluorine chitin synthesis inhibitor, was assayed for its bioactivities against several major insect and acarus pests and compared to several other pesticides: two chitin synthesis inhibitors, hexaflumuron and chlorfluazuron; a pyrethroid, permethrin; an organophosphate, acephate; a carboximid...

The D N A of a multiply-enveloped nuclear polyhedrosis virus (MNPV) of the cabbage moth Mamestra brassicae (Mb), isolated from the beet armyworm Spodoptera exigua, was analysed using restriction endonucleases SmaI, BamHI, BgllI and PstI. The size of the viral D N A was calculated to be about 152 kilobase pairs. Mapping of restriction sites on the D N A was accomplished by hybridization of 32 P-...
