Popis:	The relationship of feeding to oviposition under laboratory conditions was studied for unmated, once-mated and weekly mated postaestival female cereal leaf beetles. Peak daily egg deposition was reached early in the oviposition period for mated beetles and much later for unmated beetles. Mated females laid 2.2 to 2.6 times the average number of eggs per day as unmated females. It appears that mating exerted a physical or chemical stimulus which induced greater efficiency (food/egg ratios) and egg production. Females mated once oviposited as many as 300 fertile eggs, which is considerably higher than the number of eggs deposited by the average ovipositing cereal leaf beetle under field conditions. When the daily efficiency of ingested food was compared with daily egg deposition, females that mated weekly were more efficient than once-mated females, which were more efficient than unmated females. The daily food consumed and eggs deposited were found to be related linearly. Polynomial equations were derived that define feeding, oviposition, or efficiency for the 3 groups of beetles.
