Efficacy of entomopathogenic nematodes against white grub, Holotrichia longipennis Today, I read a paper published in Journal of Pest Science by Khatri-Chhetri et al. (2011), who tested the efficacy of two newly isolated entomopathogenic nematode species from Nepal against white grub, Holotrichia longipennis. This white grub is a very serious pest of many crops including black gram, cabbage, chilies, maize, millet, paddy soybean and tomato.

Occurrence of entomopathogenic nematodes in Egypt: Nematode Information /
Entomopathogenic nematodes from Egypt
The occurrence and distribution of entomopathogenic nematodes including Heterorhabditis indica, Steinernema abbasi and Steinernema carpocapsae have been reported from four geographical regions (Northern, Middle, Southern and Sinai Peninsula) of Egypt.
These findings were presented by Abu-Shady, N.M., Shamseldean, M.M., Abd-Elbary, N.A. and Stock, S.P. at the 50th annual meeting of the Society of Nematologists held in Corvallis, Oregon from July 17-20, 2011.
A first report of occurrence of entomopathogenic nematodes in Nepal /
Recently a survey was conducted to study the occurrence and distribution of entomopathogenic nematodes in Nepal. Although a total of 276 soil samples were collected from various habitats, entomopathogenic nematode were found only in 29 samples. Nematodes were isolates using the Galleria-baiting technique (Bedding and Akhurst,1975). Both heterorhabditid and steinernematid nematodes were identified at their species level using both molecular and morphological techniques. In this survey, the occurrence of only one species of heterorhabditids including Heterorhabditis indica and four described species of steinernematids such as Steinernema abbasi, S. cholashanense, S. feltiae and S. siamkayai were reported for the first time in Nepal (Khatri-Chhetri et al., 2010).
