The Japanese beetle,Popillia japonicaNewman is a major pest of ornamentals and turf.

Mass rearing of Tiphia vernalis Rohwer with Japanese beetle, Popillia japonica demonstrated that the Tiphia larvae parasitized on the 3rd instar white grubs was 376d shorter on average than that parasitized on the 2nd instar white grubs, and rate of cocooning was 1.

The dl sex pheromone of Japanese Beetle was synthesized by the electrophilic addition, closing ring, lactonation of nonenylcopperlithium reagent, prepared from n octyllithium, with 4 carbonyl ethyl,butanate derived from γ butyllactone.

The racemic sex pheromone of Japanese beetle was synthesized by the addition ofZ-decen-1-yl cuprate to succinic anhydride in 3 steps in an overall yield up to 60% and the Z-form purity was over 98%.
