Susceptibility of Five Insect Pests to Neoaplectana glaseri Steiner, 1929

Five species of insect pests were tested for susceptibility to parasitism and eventual killing by the nematode Neoaplectana glaseri. The nematode was able to enter the sugarcane borer, rice water weevil, cucumber beetle, and white grub, and utilize these insects as hosts to complete its entire life cycle in a substantial number of test cases. The fall army worm was found to be somewhat resistant under the test conditions. It was further concluded, from the insects found to be suscep- tible, that no major factor appears to exist which might product an incompatibility and hinder the establishment of the parasite.
