Manduca sexta, commonly known as the tobacco hornworm, is considered a significant agricultural pest, feeding on solanaceous plants including tobacco and tomato. The susceptibility of M. sexta larvae to a variety of entomopathogenic bacterial species(1-5), as well as the wealth of information available regarding the insect's immune system(6-8), and the pending genome sequence(9) make it a good ...

The vast diversity of nematodes has adapted to endure in different trophic groups as free living and parasites plants animals. In search potential entomopathogenic (EPNs), soil samples were collected from, the rhizosphere Apple orchard Darima, Nainital, Uttarakhand, India north-western Himalaya August 2019. whole experimental activity carried out at ICAR-Vivekanada Parvatiya Krishi Anusandhan S...

Black vine weevil, Otiorhynchus sulcatus (F.), is a severe pest of small fruit and nursery crops around the world. These studies were conducted to determine the efficacy of three species of entomopathogenic nematodes (Heterorhabditis marelatus, Heterorhabditis bacteriophora, and Steinernema riobrave) applied in infected host cadavers or as aqueous applications for black vine weevil larval contr...

The alkaline serine protease VCP1 of the fungus Pochonia chlamydosporia belongs to a family of subtilisin-like enzymes that are involved in infection of nematode and insect hosts. It is involved early in the infection process, removing the outer proteinaceous vitelline membrane of nematode eggs. Little is known about the regulation of this gene, even though an understanding of how nutrients and...

Infection of cocooned codling moth (cydia pomonella) larvae by the entomopathogenic nematode Steinernema carpocapsae was studied in three field experiments. Factors that varied within or between experiments included method of application, type of substrate containing cocooned larvae, time when nematodes were applied, seasonal effects, and supplemental wetting before or after nematode applicatio...

An alternative approach to applying entomopathogenic nematodes entails the distribution of nematodes in their infected insect hosts. Protection of the infected host from rupturing, and improving ease of handling, may be necessary to facilitate application. In this study our objective was to test the potential of a new method of formulating the infected hosts, i.e., enclosing the infected host i...

Animal-microbe symbioses are ubiquitous in nature and scientifically important in diverse areas, including ecology, medicine, and agriculture. Steinernema nematodes and Xenorhabdus bacteria compose an established, successful model system for investigating microbial pathogenesis and mutualism. The bacterium Xenorhabdus nematophila is a species-specific mutualist of insect-infecting Steinernema c...

Abstract Background Potato tuber worm (PTM) [ Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae)] is one of the most significant and widespread pests potato. PTM damages potatoes both in field potato storage areas. Control pest getting harder as it developing resistance to pesticides. Several entomopathogenic nematode (EPN) species have been reported successfully control numerous agric...

Bemisia tabaci is an important pest on red chili plants. The entomopathogenic nematodes Steinernema spp. has the potential to control insect populations. purpose of this study was obtain concentration most effective in controlling B. experiment conducted at Greenhouse, Faculty Agriculture, Universitas Padjadjaran, Jatinangor, from January September 2020. used experimental methods in-vitro and i...
