抽象的。提供了半合成液体饲料中野生型和白化叶螨二斑叶螨从卵到成虫的发育数据。该饲料是 Van der Geest 等人开发的饲料的改良版。 (1983).除了不添加类胡萝卜素的标准日粮外，还对添加β-胡萝卜素或维生素A的日粮进行了测试。在三种日粮的短日照条件下，野生型菌株滞育发生率很高。在标准日粮短日照条件下，白化突变体没有发现滞育。日粮中添加β-胡萝卜素后光周期反应得到部分恢复，添加β-胡萝卜素后光周期反应完全恢复。添加维生素A。在4℃冷休3周后，两种品系的饮食饲养滞育雌性均可终止滞育。结果得出结论，维生素A或维生素A衍生物可能作为光感受器色素，在红蜘蛛中诱导滞育的光周期。
Abstract. Data are presented on the development from egg to adult of a wild‐type and an albino strain of the spider mite Tetranychus urticae on a semi‐synthetic liquid diet.The diet is a modification of the diet developed by Van der Geest et al. (1983).Apart from the standard diet without added carotenoids, diets supplemented with either β‐carotene or vitamin A were tested.A high incidence of diapause was found in the wild‐type strain under short‐day conditions on all three diets.No diapause was found in the albino mutant under short days on the standard diet.Partial restoration of the photoperiodic response was obtained after addition of β‐carotene to the diet, and full restoration was found after the addition of vitamin A.Diapause could be terminated in diet‐reared diapausing females of both strains after a cold rest of 3 weeks at 4°C.The results lead to the conclusion that vitamin A or a derivative of vitamin A probably functions as the photoreceptor pigment for the photoperiodic induction of diapause in the spider mite.
