Abstract

An electroantennogram (EAG) bioassay of gas-liquid chromatographic (GLC) fractions of volatiles collected from virgin female southern corn rootworms (SCR), Diabrotica undecimpunctata howardi Barber, western corn rootworms (WCR), D. virgifera virgifera LeConte, and from D. longicornis (Say) (LON) yielded one active fraction from each species; the active fractions for the SCR and WCR represent structurally known sex pheromones for those species. Males of the WCR and those of the northern corn rootworm (NCR), D. barberi Smith and Lawrence, gave the largest antennal response to the 2R, 8R isomer of 8-methyl-2-decyl propanoate (MDP). Males of LON and D. lemniscata LeConte (LEM) gave the largest antennal response to the 2S, 8R isomer of MDP.
