Sensing of Volatile Organic Compounds by Haller's Structure in Ixodidae Tick: Electroscutumography and Olfactometric Bioassay.

Chemosensation in ticks opens a novel and unique field for scientific research. This study highlights ticks' chemosensory system to comprehend its host-searching behavior and other integrated chemistry and biology involving Haller's structure. This study combines microanatomical, electrophysiological, and behavioral experiments to investigate the role of Haller's organ in adult ticks in response to different classes of organic compounds.

Comparative response of Spodoptera litura challenged per os with Serratia marcescens strains differing in virulence.

Host plays an important role in influencing virulence of a pathogen and efficacy of a biopesticide. The present study was aimed to characterize the possible factors present in Spodoptera litura that influenced pathogenecity of orally ingested S. marcescens strains, differing in their virulence.

Characterization of putative virulence factors of Serratia marcescens strain SEN for pathogenesis in Spodoptera litura.

Two Serratia marcescens strains, SEN and ICC-4, isolated from diseased insect cadavers were observed to differ considerably in their virulence towards Spodoptera litura. The present study was aimed to characterize the possible virulence factors present in the virulent Serratia marcescens strain SEN. Both the S.

Effects of lindane on lindane-degrading Azotobacter chroococcum; evaluation of toxicity of possible degradation product(s) on plant and insect.

The effects of lindane on growth and plant growth-promoting traits of two lindane-degrading Azotobacter chroococcum strains (JL 15 and JL 104) were determined. The potential of both A. chroococcum strains to degrade lindane was also determined.
