AbstractInduction of diapause under laboratory conditions is a valuable tool for the study of dormancy in economic pests such as the swede midge, Contarinia nasturtii Kieffer (Diptera: Cecidomyiidae). In the present study, diapause in larval swede midge was achieved via manipulation of rearing photoperiod and temperature. Frequency of diapause was assessed by sieve separation of diapause cocoons from pre-sifted peat substrate following emergence of pupating individuals. Mean diapause frequency for swede midge larvae reared under cool conditions with short day length or cool conditions with decreasing day lengths were 45.2% and 19.5%, respectively. Only 1.2% of swede midge reared under warm, long day length conditions entered diapause. A small percentage of larvae neither pupated nor entered diapause and remained in substrate long after other individuals had emerged as adults. This behaviour was more prevalent under cool and short or decreasing day length rearing conditions. Approximately 76% of the larvae used for diapause induction were recovered with the present larval and cocoon retrieval method, and premature (larval and pupal) mortality averaged 18.2%. Although diapause occurred in the present study, conditions resulting in higher diapause frequencies should be investigated and attempts should be made to improve survival and recovery of individuals.

The effects of infestation by Contarinia nasturtii (Kieff.) on the growth and yield of swedes were observed in a centric-systematic-area sample consisting of 720 individually tagged plants. Severe infestation by the first generation caused multiple haeding and some reduction of yield, though it was attack by the second generation that more strongly depressed yield. From the results of laboratory experiments described it is inferred that it should be possible to achieve satisfactory control by simple cultural procedures designed to bury the pupal cocoons too deeply in the soil to permit successful emergence of the adult midges.
