Japanese beetles (Popillia japonica) are one of the most damaging insect pests of many agricultural and horticultural crops, ornamental plants and turfgrasses. Larvae of Japanese beetles are also called as grubs that mainly damage plant roots whereas their adults damage only aboveground plant parts like flowers, fruits, leaves and twigs.
Volatile organic compounds (VOCs) with nematicidal activities are naturally occurring chemicals generally found in and easily emitted as vapors and gases from many living organisms like bacteria and fungi, and plants.
The fall armyworm, Spodoptera frugiperda is one of the most economically important pests of different plant species including corn, sorghum, forage, and turf grasses. Although fall armyworm larvae actively damage crops throughout the United States during growing season, they generally die when harsh winter begins in northern, central and eastern United States. Then question arises how they could re-infest fields and cause damage to the crops grown in these areas during spring and summer again.
Six newly described species including Steinernema beitlechemi, Steinernema fabii, Steinernema innovation, Steinernema jeffreyense, Steinernema sacchari and Steinernema tophus have been reported from South Africa.
Plant-parasitic nematodes including root-knot nematodes are the most damaging pest of many organically grown vegetables like beans, carrots, cucumbers, eggplants, melons, okra, peas, peppers, potatoes, squash and tomatoes.
A new species of entomopathogenic bacteria was isolated from Steinernema aciari nematode is now called as Xenorhabdus ishibashii.
Four beneficial nematodes including Heterorhabditis bacteriophora, Steinernema feltiae, Steinernema intermedium and Steinernema kraussei have been reported from Portugal.
A new beneficial entomopathogenic nematode collected from a sugarcane field located in the KwaZulu-Natal province of South Africa was named as Steinernema sacchari.
A new beneficial nematode identified as Steinernema tophus was collected from a vineyard located in Clanwilliam, South Africa.
Biological control of plant parasitic nematodes with different organisms was one of the most important topics were thoroughly discussed at the 6th International Congress of Nematology, which was recently held in Cape Town, South Africa from May 4-9, 2014.
