The virulence of and reproduction capacity of six entomopathogenic nematode strains of species Steinernema longicaudum (Rhabditida: Steinernematidae) to second stage larvae of mealworm Tenebrio molitor (Coleoptera: Tenebrionidae) was evaluated under laboratory conditions.

Vibriosis has been implicated in major losses of larvae at shellfish hatcheries. However, the species of Vibrio responsible for disease in aquaculture settings and their associated virulence genes are often variable or undefined.

Hessian fly larval feeding triggers enhanced polyamine levels in susceptible but not resistant wheat
Hessian fly (Mayetiola destructor), a member of the gall midge family, is one of the most destructive pests of wheat (Triticum aestivum) worldwide. Probing of wheat plants by the larvae results in either an incompatible (avirulent larvae, resistant plant) or a compatible (virulent larvae, susceptible plant) interaction.

Efficacy of different microbial pesticides was assessed in laboratory bioassays on third instar larvae of S. litura. Results revealed that 12 days after treatment, B. bassiana showed the highest virulence of 96.00 per cent against S. litura followed by M. anisopliae with 80.00 per cent and the lowest virulence was recorded in L. lecanii with 60.00 per cent and 20.00 per cent mortality in control.

The common cutworm (turnip moth) Agrotis segetum (Denis & Schiffermuller) is nearly cosmopolitan insect pest of potato. The efficacy of the entomopathogenic nematodes (EPN) Steinernema carpocapsae and Heterorhabditis indica was evaluated against different developmental stages of A. segetum under laboratory conditions. In laboratory studies, significant mortality of second instar larvae was recorded by H. indica (73.3-100 per cent) and 63.3-100 per cent by S. carpocapsae after 48 hrs of treatment at EPNs suspension of 50-300 IJs/ml (1 ml per larva).

A nucleopolyhedrovirus (NPV) was isolated from diseased larvae of Malacosoma franconicum (Denis & Schiffermüller, 1775), collected from the northeastern part of Turkey. Light and electron microscopic observations showed that this virus is a multiple nucleopolyhedrovirus (MNPV).
