Citrus mealybug Planococcus citri is a serious insect pest of many greenhouse plants as well as fruit crops in the field. There are different biological, chemical and cultural approaches available for the management of citrus mealybugs.Read More
Efficacy of two entomopathogenic nematodes including Heterorhabditis zealandica strain X1 and H. bacteriophora Strain GPS11 was studied in the field against grape root borer Vitacea polistiformis (Williams et al., 2010). This borer can damage roots of both wild and cultivated Vitis and Muscadinia grapes and is considered as a major pest of grapes grown in the eastern United States. According to Williams et al. (2010), both H. zealandica and H. bacteriophora can cause up to 92% control of grape root borer and they can also persist in the soil for a extended period after their application. Read following literature for more information on interaction between entomopathogenic nematodes and the grape root borers.
