| Abstract/Contents: | "Dosage-mortality response, toxicological symptoms, and events leading to death following topical treatment of 3rd stage grubs of a New Jersey population of Popillia japonica Newman were studied. The 8-day LD50 and LD95 values for chlorpyrifos were 1.88 and 55.24 Υg/grub, respectively. For the slower-acting dieldrin, the 14-day LD50 and LD95 were 48.7 and 1768 Υg/grub, respectively; the high LD50 for dieldrin may be indicative of dieldrin resistance. Grubs in advanced stages of insecticide poisoning were characterized by distinct symptoms: shrinkage in size and reduction in body weight to ca. 50%; yellow-brown coloration of the body, instead of the normal whitish appearance; and moribundity. Preceding the onset of the advanced stage of poisoning, the treated grubs became hyperactive (locomotor excitability) and moved up to the soil surface, remained there for one or more days, progressed to the advanced stage of poisoning, and died. Some surfaced grubs, apparently recovering from insecticide action, dug back into the soil after a day or two." |
