Both fifth and sixth instar Choristoneura fumiferana were fed C. fumiferana nuclear polyhedrosis virus (CfNPV) and assayed for trypsin, chymotrypsin, aminopeptidase, and carboxypeptidase activities. CfNPV infection affected trypsin and chymotrypsin a

Resistance to the organophosphate insecticide, malathion, in a strain of Culex tarsalis mosquitoes is due to increased activity of a malathion carboxylesterase (MCE). To determine whether resistance was due to a qualitative or quantitative change in

The infectivity, dissemination, and transmissibility of wild-type Sindbis (SIN) virus were studied in Aedes aegypti (L.). There was an initial decline in the viral titer of whole mosquitoes for 3 d after ingestion of virus, followed by a gradual incr

The effects of maize-derived compounds, DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one) and MBOA (6-methoxybenzoxazolinone), on detoxification enzymes of the European corn borer, Ostrinia nubilalis (Hubner), were examined. In vitro , DIMBOA inc

Detoxification processes in the European corn borer, Ostrinia nubilalis , fed on either meridic diet or corn leaves from three plant lines with either low, intermediate, or high resistance to leaf damage were investigated by measuring cytochrome P450

Metabolism of the plant-derived phototoxic insecticide, α-terthienyl (α-T), was examined in larvae of the mosquito Culex tarsalis Coquillett (Diptera: Culicidae). Results indicated that metabolism of [ 3 H]α-T occurred and that the resulting hydro

The mode of action of the plant-derived phototoxic insecticide α-terthienyl (α-T), was examined in larvae of the mosquito Aedes aegypti (Linn.) (Diptera: Culicidae). Exposure of larvae to the toxin in the presence of near-ultraviolet light resulted

Malathion resistance in a strain of Culex tarsalis mosquitoes is due primarily to the activity of a malathion carboxylesterase (MCE). The resistant strain was 150 times more resistant to malathion than the susceptible strain and was weakly resistant

The biochemical basis for the tolerance of the European corn borer,Ostrinia nubilalis, to the phototoxinα-terthienyl was investigated by measuring the midgut polysubstrate monooxygenases and glutathioneS-transferase activities.α-Terthienyl administ

Mated female Rhodnius prolixus were fed citrated rabbit blood containing cordycepin, cycloheximide and 5-fluorouracil. The effect of these compounds on cathepsin B, cathepsin D and aminopeptidase levels in the posterior midgut was determined. Cyclohe
