Description
The entomogenous nematodes, Steinernema feltiae, S. bibionis and S. glaseri, were almost uninfective against larvae of scarabaeid beetles. According to Ishibashi et al (1987), the infective juveniles (J3) of S.feltiae (DD-136) were stimuleatd to move actively by low concentration (10-62.5ppm) of oxamyl.<BR>Therefore, in this paper, the mixing applications of S. feltiae Mexican with the low concentration of chemicals were investigated against 3 instar larvae of Anomala schönfeldti. The mixture of Mexican (12×105/m2) with fenitrothion (×1000, 5000, dil.) and diazinon (×1000, 5000, dil.) to larvae showed significantly higher potentiation than only insecticides on the tests. The mechanism of action by mixing application may be base on decrease of the larval defense against nematodes under the influence of insecticides.
