摘要
Investigations were conducted on oviposition by laboratory-reared oblique-banded leafrollers, Choristoneura rosaceana Harris. In paper-bag oviposition chambers, females deposited their egg masses in a significantly nonrandom, uniform manner in 16 of 20 replicates. In petri dish oviposition chambers, gravid females were exposed to egg masses recently deposited by other females. As determined by the magnitude of the mean direction vector of the second egg mass in relation to the first, females detected and avoided egg masses laid by other females. In addition, they avoided waxed paper from which a recently oviposited egg mass had been removed. This phenomenon is most likely due to a pheromone laid down with each egg mass.
