Expansive chemical-based vector control has resulted in development of vector resistance to different insecticides harnessed for prevention of disease transmission in public health. The environmentally safe insect growth regulators and microbial larvicides provide potential tools for insecticide resistance management. The efficacy and persistence of Dimilin GR-2% and Mosquiron 10 EC insect grow...

Plants are part of biodiverse communities and frequently suffer from attack by multiple herbivorous insects. Plant responses to these herbivores are specific for insect feeding guilds: aphids and caterpillars induce different plant phenotypes. Moreover, plants respond differentially to single or dual herbivory, which may cascade into a chain of interactions in terms of resistance to other commu...

Herbivorous insects use diverse feeding strategies to obtain nutrients from their host plants. Rather than acting as passive victims in these interactions, plants respond to herbivory with the production of toxins and defensive proteins that target physiological processes in the insect. Herbivore-challenged plants also emit volatiles that attract insect predators and bolster resistance to futur...

In this study we produced transgenic tobacco plants by overexpressing a serine proteinase inhibitor gene, SaPIN2a, from the American black nightshade Solanum americanum under the control of the CaMV 35S promoter using Agrobacterium tumefaciens-mediated transformation. SaPIN2a was properly transcribed and translated as indicated by Northern blot and Western blot analyses. Functional integrity of...
