AM1-type molecular orbital calculations were performed on the geometry-optimized structures of various 4-(1’, 5’ - dimethly -4’ - heptenylidene) -1- methylcyclohexene isomers. It was found that the major component (4Z, 4’E isomer) of the sex pheromone of Eurygoaster integriceps is very dissimilar in chemical composition to the other isomers, although the stabilities and heats of the formation characteristics are comparable.

In insects, nodulation is the first step in cellular defense reactions to bacterial, fungal, and some viral infections. The hypothesis was posed that the hemipteran pest E. integriceps produces melantoic nodulation reactions to bacterial challenge and that eicosanoids mediate these reactions.

Sampling statistics for development of a sampling plan for adult Sunn Pest, Eurygaster integriceps Puton, in their overwintering habitat were generated based on numbers of live and total adults in 1 to 4 litter samples per tree. Taylor’s power law was used to estimate optimum sample size, critical stop lines for sequential sampling and a sequential difference test.

The results from the field studies reflected that developmental biological data on sum of degree-days as a predictive tool could be useful in better decision making to start chemical applications as soon as the appearance of n1 until n4 for Sunn pest control.
