Begomoviruses are a major group of plant viruses, transmitted exclusively by Bemisia tabaci (Gennadius) in a persistent circulative non-propagative manner. The information regarding molecular and cellular basis underlying Begomovirus - whitefly interaction is very scarce. Evidences have suggested that the insect gut possesses some crucial protein receptors(More)
Alterations in intracellular-calcium (Ca2+)i homeostasis is critical to Aeromonas hydrophila-induced headkidney macrophages (HKM) apoptosis of Clarias gariepinus, though the implications are poorly understood. Here, we describe the role of intermediate molecules of Ca2+-signaling pathway that are involved in HKM apoptosis. We observed(More)
Thrips palmi Karny is a globally distributed polyphagous agricultural pest. It causes huge economic loss by its biological behaviors like feeding, reproduction and transmission of tospoviruses. Since T. palmi shows close morphological similarities with other thrips species, we employed mitochondrial cytochrome oxidase 1 (mtCO1) gene as a molecular marker.(More)
The effect of Groundnut bud necrosis virus (GBNV) infection on the life history traits of its vector Thrips palmi and its feeding preference on GBNV-infected plants were studied. A significant difference was observed in the developmental period (1st instar to adult) between the GBNV-infected and healthy thrips, wherein the developmental period of(More)
