Potentiality of entomoparasitic nematode, heterorhabditis bacteriophora infecting african mole-cricket, gryllotalpa africana (gryllotalpidae: orthoptera).

Abstract: Pots trial was conducted to study the effect of two methods of application and five concentrations of entomoparasitic nematode, H. bacteriophora on its survival in soil as well as in the host of African mole-cricket G. africana. Results revealed that, the mole-cricket infection with entomoparasitiic nematode,.generly occurred, after 7 days of application as soil surface; whereas it clearly occurred, after 3 days of bait application. The nematode concentration of 2500 IJS(Invective Juveniles) / a pot / an insect individual was the most effective on all treated mole-cricket insects of the nymph and adult stages after 3 and 7 days of the two application methods. Poison bait application caused an increase of extracted US from soil than that of soil surface application. Survival of nematodes depended on G. africana stage, nematodes' concentrations and method of application. When adult male was treated with i500 US as soil surface application, 146250 US had been got from one insect. Poison bait application method was the most effective on nematode survival inside treated mole-cricket insects in spite of the tested concentrations.
