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.
Read MoreKill fall armyworms now and stop their northward migration during spring /
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.

Prevent corn damage from The western corn rootworms (Diabrotica virgifera virgifera) using beneficial entomopathogenic nematodes.
Read MoreA new species of entomopathogenic Steinernema nematodes /
A new species of entomopathogenic Steinernema nematode that isolated from southwest Bohemia, Czech Republic was identified and named as Steinernema poinari sp. n. (Nematoda : Steinernematidae) using both morphological and molecular techniques (Mráček et al., 2014). This new species was recovered from soil using Galleria baiting technique described by Bedding and Akhurst (1975).
Read MoreBeneficial Steinernema carpocapsae nematodes for sod webworm control /
Beneficial Steinernema carpocapsae nematodes have a potential to control tropical sod webworm, Herpetogramma phaeopteralis, one of the most damaging pests of turfgrass. Sod worms are lepidopterous insects that cause a serious damage to turfgrasses that are grown in the athletic fields, golf courses, home lawns and recreational parks. Adult moths do not cause any type of damage to turfgrass but their larval stages feed on turfgrass and reduce its aesthetic value.
Read MoreThree beneficial nematodes for Queensland fruit fly control /
Three beneficial nematodes including Heterorhabditis bacteriophora, Steinernema carpocapsae and Steinernema feltiae have a potential to use as a biological control agents to manage populations of Queensland fruit fly, Bactrocera tryoni, which is one of the most economically important insect pest of many fruit crops.
Read MoreA new Steinernematid nematode species from India /
A new Steinernematid nematode species isolated from central part of India was named as Steinernema dharanaii sp. n. (Nematoda : Steinernematidae) by Kulkarni et al (2012) using both morphological and molecular techniques based on ITS rDNA. These researchers found that this new species was closely associated with 'glaseri-group' of Steinernema spp. but its infective juveniles (Fig. 1), males and females had distinct morphological characteristics.
Read MoreTwo beneficial entomopathogenic nematodes for cucurbit fly control /
Two beneficial entomopathogenic nematodes including Heterorhabditis bacteriophora (Fig.1) and Steinernema carpocapsae (Fig. 2) have showed a potential to control cucurbit flies, Dacus ciliatus (Kamali et al., 2013). These nematodes are considered as beneficial nematodes because they have been used as biological control agents to control insects that are damaging to crops and harmful to animals
Read MoreBiological control of plant parasitic nematodes with fungi and bacteria /
Biological control is the introduction and/or establishment of natural enemies including parasites, predators and pathogens (fungi and bacteria) to suppress the population densities of plant-parasitic nematodes lower than their economic threshold level. Following are 24 nematophagous fungi and six pathogenic bacteria have a potential to use as biological control agents to control different kinds of plant-parasitic nematodes.
