A new species of entomopathogenic Steinernema nematodes by Ganpati Jagdale

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).

Beneficial Steinernema carpocapsae nematodes for sod webworm control by Ganpati Jagdale

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.

Three beneficial nematodes for Queensland fruit fly control by Ganpati Jagdale

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.

A new Steinernematid nematode species from India by Ganpati Jagdale

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.

Two beneficial entomopathogenic nematodes for cucurbit fly control by Ganpati Jagdale

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

Biological control of plant parasitic nematodes with fungi and bacteria by Ganpati Jagdale

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.

Biological control of the peanut burrower bug, Pangaeus bilineatus by Ganpati Jagdale

The peanut burrower bugs are true bugs because they belong to an insect family Cydnidae in the order, Hemiptera. The peanut burrower bugs are scientifically known as Pangaeus bilineatus and considered as one of the major insects pests of peanuts in the peanut, Arachis hypogaea producing States in the U.S. (Lis et al. 2000) .

Antibiotics from entomopathogenic bacteria Xenorhabdus cabanillasii by Ganpati Jagdale

Entomopathogenic Steinernema riobrave is a warm adapted nematode species that uses an intermediate foraging strategy that lie between the ambush “sit and wait” strategy and cruise strategy to find and infect its both the mobile/sedentary insects at the soil surface or immobile stages deep in the soil and after infection, it uses its symbiotic bacteria, Xenorhabdus cabanillasii (Tailliez et al., 2006) to kill insect hosts.

Steinernema feltiae for Codling Moth Control in the October by Ganpati Jagdale

The codling moth, Cydia pomonella is one of the most damaging pets of apples, pears and walnuts. Adult moths are gray in color with dark brown band at the tip of wings.  Larvae are white in color with dark brown head.  Only larvae of codling moth cause damage to fruits and adults do not cause any damage to either apple or pear fruits or trees.

Steinernema costaricense the beneficial Nematode found in Missouri by Ganpati Jagdale

The measurement of both the morphological and molecular characteristics showed that the newly isolated beneficial nematode from Missouri, USA is closely related to the entomopathogenic nematode Steinernema costaricense, which was originally isolated from Costa Rica in 2007 (Uribe-Lorio et al., 2007).

Two biological agents for the control of strawberry root weevils by Ganpati Jagdale

Strawberry root weevils [Otiorhynchus ovatus] are one of the most important insect pests of strawberry crop.  Adults of strawberry root weevil feed on the edges of strawberry leaves [leaf notching] but this damage is not considered as economically important like the damage caused by their larval stages to strawberry roots [root pruning].
