Eriosoma lanigerum (Hausmann) (Hemiptera: Aphididae), woolly apple aphid (WAA) is an important pest on apples globally and a key of production in South Africa. The has developed some level resistance against several chemical insecticides. Entomopathogenic fungi (EPF) have been identified as promising biological control agents wide array insect pests. main aim this study was to conduct survey lo...

The entomopathogenic bacterium, Xenorhabdus nematophila was isolated from the hemolymph of Galleria mellonella infected with Steinernema carpocapsae. The bacterial cells and its metabolic secretions have been found lethal to the Galleria larvae. Toxic secretion in broth caused 95% mortality within 4 d of application whereas the bacterial cells caused 93% mortality after 6 d. When filter and san...

Entomopathogenic nematodes (EPNs) are known agents in pest biological control. Environmental factors can influence on populations of soil-inhabitant like EPNs agricultural lands. In the current study, after selecting a suitable study site (33.20-33.42 N and 48-48.55 E), soil sampling (250 samples) May to July 2019, infectious juveniles were extracted from samples according bait method. Accordin...

Abstract Background Entomopathogenic nematodes (EPNs) belonging to the Heterorhabditis spp. harbour symbiotically associated bacteria which are toxic a wide range of insect pests. Isolation, purification, characterization and mass multiplication such will be promising strategy in management This study was carried out isolate EPN from different locations, purify bacterial colonies, characterize ...

Abstract Background Banana fruit scarring beetle (BFSB), Basilepta subcostata (Jac.) (Chrysomelidae:Coleoptera), is an important insect pest feeds on leaf and fingers, which affects the cosmetic value of fruit. The distributed in Assam, Bihar, West Bengal, Chhattisgarh, North-eastern Hill regions India. Results currently managed by foliar spray with insecticides. In order to identify eco-friend...

Five bacterial strains were isolated from the hemocoel of the greater wax moth larvae (Galleria mellonella) infected with the entomopathogenic nematodes: Heterorhabditis bacteriophora HP88, Heterorhabditis indicus RM1 and Heterorhabditis sp (S1), Steinernema abbasi and Steinernema sp. (S II). Strains were identified as Photorhabdus luminescens HRM1, P. luminescens HS1, P. luminescens HP88, Xeno...

The implementation of infection models that approximate human disease is essential for understanding pathogenesis at the molecular level and for testing new therapies before they are entered into clinical stages. Insects are increasingly being used as surrogate hosts because they share, with mammals, essential aspects of the innate immune response to infections. We examined whether the larva of...

Nonmammalian model systems of infection such as Galleria mellonella (caterpillars of the greater wax moth) have significant logistical and ethical advantages over mammalian models. In this study, we utilize G. mellonella caterpillars to study host-pathogen interactions with the gram-negative organism Acinetobacter baumannii and determine the utility of this infection model to study antibacteria...
