In biological control programmes introduced natural enemies compete with indigenous enemies for hosts and may also engage in intraguild predation when two species competing for the same prey attack and consume one another. The large pine weevil, Hylobius abietis L. (Coleoptera: Curculionidae), is an important pest of coniferous reforestation in Europe. Among its natural enemies, the parasitoid ...

Associations between endosymbiotic bacteria and their hosts represent a complex ecosystem within organisms ranging from humans to protozoa. Drosophila species are known to naturally harbor Wolbachia and Spiroplasma endosymbionts, which play a protective role against certain microbial infections. Here, we investigated whether the presence or absence of endosymbionts affects the immune response o...

Aims: Entomopathogenic nematode (EPN) and its symbiotic bacterium are used worldwide as microbial control agents. Toxins from EPN bacteria were isolated provided basis for using this potential resource biocontrol agent against vegetable diseases pests.
 Study Design: The toxins extracted 28 strains of associated with entomopathogenic nematodes. insecticidal activity antibiotic pests determ...

This publication describes current methods for managing wireworms in sweet potato. Wireworms, the larvae of click beetles, are most damaging insect pests those that infest foliage and roots. Soil tillage crop rotation can suppress populations these root but adequate management requires diligent surveillance use insecticides. Describes new research on with alternative insecticide active ingredie...

Lepidopteran pest cause significant loss in quantity and quality of produced many agricultural horticultural crops. Therefore management strategies should aim to reduce their population below threshold level. Though chemical pesticides are recommended for controlling these insect pests, biocontrol agents mostly IPM programme.The most important bio-control agent is the entomopathogenic nematodes...
