AbstractTimulla oculata(Fabr.) is redescribed and ten nominal species of OrientalTimullaare placed in synonymy with it. Fourteen subspecies, including two new ones(T. oculata rosemariaesubsp.n. andT. oculata timorensissubsp.n.), are recognised and keys to the subspecies are given. Geographic variation and the application of the polytypic species concept are discussed. The structure of the male genitalia ofTimullais related to dispersal strategies. The distribution and subspeciation ofT. oculatais discussed in relation to the geological history of South East Asia and the Malay Archipelago.

摘要:

AbstractIn several growers' reportsSolatium lycopersicum, Sambucus nigra. Thymus vulgaris, Salvia officinalis, Artemisia absinthium, A. abrotanum, andAllium cepaare said to decrease the oviposition ofPieris brassicae, P. rapaeandP. napi.In the present study the butterflies were fed with honey automats and reared throughout the year in artificial light in an insec‐tarium. In a dual‐choice chamber with a slow throughflow of air two equally sized cabbage leaves were placed on opposite sides. Significantly fewer eggs were layed on the cabbage leaf on which extracts of the mentioned plants had been applied. Ten butterflies were used in each experiment. The chemoreceptors and the chemicals involved are not identified but the inhibitory substances are surely secondary plant substances. Acceptance or rejection of secondary plant metabolics determines the complicated food relationships between plants and insects. The use of secondary plant substances for ecological control of insect pests is propo
