Wolbachia are maternally inherited intracellular bacteria that infect a wide range of arthropods and nematodes and are associated with various reproductive abnormalities in their hosts. The infection by Wolbachia of the psocid, Liposcelis tricolor (Psocoptera: Liposcelididae), was investigated using long PCR amplification of the wsp gene that codes for a Wolbachia surface protein. The results s...

The seasonality of litter insect abundance and its relationship with rainfall was analyzed in a wet evergreen forest on the windward side of south Western Ghats. Monthly litter samples were collected using Berlese funnels during 4 seasons of a year: southwest monsoon season June-August), northeast monsoon season (September-November), summer (March -May) and pre-summer season (December-February)...

Recent phylogenetic analyses, both morphological and molecular, strongly support the monophyly of most insect ‘orders’. On the contrary, the Blattaria, Psocoptera, and Mecoptera are defi nitely paraphyletic (with respect of the Isoptera, Phthiraptera, and Siphonaptera, respectively), and the Phthiraptera are possibly diphyletic. Small relictual subclades that are closely related to the Isoptera...
