Oviposition by Mamestra brassicae (L.) (Lep., Noctuidae) in relation to age, time of day and host plant
Journal of Applied Entomology - Zeitschrift für angewandte Entomologie 125 (3), 161-163
Abstract: The age at which females begin to lay, the daily pattern of oviposition, the influence of host-plant material on egg-laying as well as the host preference of Mamestra brassicae L. (Lep., Noctuidae) were investigated under laboratory conditions. The females began to oviposit during the third, fourth and fifth scotophase after emergence. A great variability in daily female fecundity was observed. The highest level of oviposition occurred during the fifth day. Females oviposited during the whole scotophase, but maximal oviposition occurred during the second hour. The females without host-plant material laid fewer eggs than females with host-plant material (cabbage leaves Brassica oleracea var. capitata). In two-choice tests, the females preferred to oviposit on cabbage rather than chrysanthemum, but there was no difference in the mean number of eggs laid on cabbage and tomato. There were significantly greater mean numbers of total eggs deposited on tomato than on chrysanthemum.
