چکیده

During work on the control of human pediculosis Craufurd-Benson & Macleod found that body lice, which normally have a high resistance to derris, were rapidly killed when high-boiling tar acids were added to the insecticide. A similar effect was observed in experiments with the sheep ked, Melophagus ovinus, when mixtures of cresylic acid and diphenylamine were applied either as a dusting powder with a china clay base, or as a liquid wash. It was suspected that a rapid penetration of the insecticide through the insect cuticle, induced by the presence of the solvent, might be responsible for this increase in efficiency. If the synergy, already found to exist between derris or diphenylamine on the one hand, and phenols on the other, could be extended to other insecticides and solvents, then an understanding of the factors governing the phenomenon would have considerable value in deciding the correct mode of presentation of a particular insecticide.

Comparison of rates of penetration through insect cuticle of amphiphylic analogs of insect pyrokinin neuropeptides.

Rates of penetration through the cuticle of amphiphylic analogs, synthesized by addition of 6-phenylhexanoic acid or 9-fluoreneacetic acid or 1-pyrenebutyric acid to the amino terminus of the pentapeptide Phe-Thr-Pro-Arg-Leu-amide, were assessed by quantitative analysis using reversed phase liquid chromatography. The analogs effectively penetrated the cuticle of both the adult American cockroac...

Increased insect virulence in Beauveria bassiana strains overexpressing an engineered chitinase.

Entomopathogenic fungi are currently being used for the control of several insect pests as alternatives or supplements to chemical insecticides. Improvements in virulence and speed of kill can be achieved by understanding the mechanisms of fungal pathogenesis and genetically modifying targeted genes, thus improving the commercial efficacy of these biocontrol agents. Entomopathogenic fungi, such...

Conference on International Agricultural Research for Development Pathogenicity of Entomopathogenic Fungi Metarhizium anisopliae Against Termites

Biological control with pathogenic fungi is a promising alternative to chemical control against the subterranean termite. Biological control with pathogenic fungi might provide longlasting insect control without damage to the environment or non-target organisms. M. anisopliae is one of several natural agents for controlling a broad range of insects by direct penetration of the host cuticle. Usi...
