Cry15Aa protein, produced by Bacillus thuringiensis serovar thompsoni HD542 in a crystal together with a 40-kDa accompanying protein, is one of a small group of nontypical, less well-studied members of the Cry family of insecticidal proteins and may provide an alternative for the more commonly used Cry proteins in insect pest management. In this paper, we describe the characterization of the Cr...

A series of N-substituted 5-chloro-6-phenylpyridazin-3(2H)-one derivatives were synthesized based on our previous work; all compounds were characterized by spectral data and tested for in vitro insecticidal activity against Plutella xylostella. The results showed that the synthesized pyridazin-3(2H)-one compounds possessed good insecticidal activities, especially the compounds 4b, 4d, and 4h wh...

The primary objective of the study was to evaluate biological activity Citrus aurantifolia essential oil (CAEO) with emphasis on antioxidant, antimicrobial, and insecticidal activity, chemical composition, antimicrobial effect its vapor phase in situ various food models. We determined main volatile components CAEO as α-phellandrene (48.5%) p-cymene (16.5%). antioxidant high reached 74.5 ± 0.5%,...

Pyrethrum is the natural extract that occurs in the flowers of Chrysanthemum cinerariaefolium and Chrysanthemum cineum. Pyrethrum has long been recognized as possessing insecticidal properties; over the years, first the chemical extracts of pyrethrum, and then more recently, the specific synthetic chemical analogs have been produced. The six active insecticidal compounds of pyrethrum are called...

' Nine of the subject compounds have been synalog, 2,2-dimethyl-3-thiophanone 0-(methylcarthesized and evaluated for their insecticidal bamoyl)oxime, elicits a miticidal response; this properties. These materials are characterized by material is also toxic to the aphid and housefly good activity to the housefly, a lower order of efand shows a high order of systemic activity. In fectiveness agai...

The butanol fraction of the leaves of Castanospermum australe Cunn. & Fraser., was tested on adult Callosobruchus analis (pulse beetle) for its insecticidal activity by impregnation method at concentration of 3, 9, 48, 240 and 354 μg / cm. The result showed that the extract is toxic to Callosobruchus analis and the LD50 was found to be 38 g/cm . KeywordsCallosobruchus analis, Castanospermum au...

Baculoviruses are widely used both as protein expression vectors and as insect pest control agents. This video shows how lepidopteran larvae can be infected with polyhedra by droplet feeding and diet plug-based bioassays. This accompanying Springer Protocols section provides an overview of the baculovirus lifecycle and use of baculoviruses as insecticidal agents, including discussion of the pro...
