颈双缘姬蜂是小菜蛾蛹期的寄生蜂，试验蜂种来自马来西亚。笔者在室内对其一些生物学、生态学特性作了观察，并在玻璃房内进行了放蜂试验。在２０℃下，雌蜂的发育历期为１７．３天，雄蜂为１６．７天；２３℃下，相应为１２．２天；２７℃则为１１．０和１０．５天。提供蜜糖水和清水，成蜂寿命长（否则很快死亡），如在２３℃下雌蜂可活５２．０天，雄蜂活３７．５天。在我们的试验条件下被寄生过的寄主蛹，大约只有３５％发育至成蜂。当三种不同状态的寄主蛹同时存在时，该蜂较喜寄生有丝茧且连菜叶的小菜蛾蛹，其次为有丝茧蛹，不喜寄生无丝茧蛹；此外，它喜寄生预蛹，其次是蛹早期，对蛹后期寄生较少。在２×２×３米的玻璃房中散放此蜂三次，放蜂量为４０♀６９时，寄生死亡率高达９０．９２％；２０♀３５时，寄生死亡率为７６．６３％；１０♀１７时，寄生死亡率为５０．２９％。
Juglans macaques are parasitoids in the pupal stage of Plutella xylostella, and the test species is from Malaysia. The author observed some of its biological and ecological features indoors and conducted a beekeeping experiment in a glass house. At 20 ° C, the developmental duration of the female was 17.3 days and that of the male was 16.7 days, corresponding to 12.2 days at 23 ° C and 11.0 days and 10.5 days at 27 ° C. Provide honey and water, bees have long life span (or die soon), such as female bees can live 52.0 days at 23 ℃, male bees live 37.5 days. Only about 35% of host pupae parasitized under our experimental conditions developed into adult bees. When the three different states of the host pupae co-exist, the bee prefer to parasitize the silkworm cocoon even with the cabbage leaf moth pupae, followed by silkworm cocoon pupae, do not like parasitic silkworm cocoon pupa; In addition, Pupae, followed by the early pupae, parasitic parasites on the late pupa less. This bee was released three times in a glass house of 2 × 2 × 3 meters with a parasitic mortality rate of 90.92% at a rate of 40♀69 and a parasitic mortality rate of 76.63% at 20♀35. At 10♀17, the parasitic mortality rate was 50.29%.
