Entomopathogenic nematodes and insect parasitoids can work together to kill insect pests

Ganpati Jagdale — Sat, 21 Aug 2010 18:12:02 +0000

In a laboratory study, recently it has been demonstrated that the combined application of an entomopathogenic nematode, Heterorhabditis indica and an insect parasitoid, Habrobracon hebetor can enhance the mortality of Indianmeal moth, Plodia interpunctella.

Control Rhipicephalus (Boophilus) microplus with an entomopathogenic nematode Steinernema glaseri

Ganpati Jagdale — Sun, 13 Jun 2010 20:08:26 +0000

It has been demonstrated that the entomopathogenic nematode Steinernema glaseri CCA strain can infect engorged Rhipicephalus ( Boophilus) microplus female ticks within two hours of exposure. However, nematodes can cause over 90% mortality of ticks when they are in contact with the ticks for 24 hours.

Biological control of the cattle tick Rhipicephalus microplus with entomopathogenic nematodes

Ganpati Jagdale — Fri, 26 Mar 2010 15:27:01 +0000

Recently, it has been demonstrated that the entomopathogenic nematode, Heterorhabditis amazonensis strain RSC-5 have a potential to use as a biological control agent against cattle tick, Rhipicephalus (Boophilus) microplus (Monteiro et al., 2010), which is considered to be the most important tick parasite of livestock in the world. This hardy tick can be found on many hosts including cattle, buffalo, horses, donkeys, goats, sheep, deer, pigs, dogs and some wild animals. This tick can also transmit babesiosis (cattle fever), which is caused by the protozoal parasites, Babesia bigemina and Babesia bovis. Also, transmit anaplasmosis caused by Anaplasma marginale.

A record of new entomopathogenic nematode species from Brazil

An entomopathogenic nematode in a soil sample collected from a natural forest in Mato Grosso do Sul state, Brazil was described using both morphological and molecular characteristics as a new species “Steinernema brazilense (Rhabditida: Steinernematidae)” (Nguyen et al., 2010).

Control oriental beetles, Anomala orientalis with an entomopathogenic nematode Steinernema scarabaei

Ganpati Jagdale — Mon, 18 Jan 2010 16:54:32 +0000

The oriental beetle, Anomala orientalis is one of most damaging white grub species of turfgrass. An entomopathogenic nematode, Steinernema scarabaei has been used as effective biological control agent against these beetles. When infective juveniles of this nematode applied at the rate of 2.5 billion per hectare of turfgrass they can suppress over 77% population of oriental beetles (Koppenhofer and Fuzy, 2009).

Occurrence of entomopathogenic nematode Steinernema feltiae in Slovenia

Ganpati Jagdale — Thu, 14 Jan 2010 04:55:37 +0000

Presence of an entomopathogenic nematode, Steinernema feltiae (Rhabditida: Steinernematidae) was recorded for first time in soil samples collected from grasslands and field crops in central part of Slovenia. Nematodes were isolated using Galleria-baiting technique (Bedding and Akhurst, 1975) and identified using molecular technique.
