Abstract

Tupiocoris cucurbitaceus (Spinola) (Hemiptera: Miridae) is a predator of whiteflies (Hemiptera: Aleyrodidae) present in several American countries. Rearing this bug requires the use of plants as ovipositional substrate and a prey to feed on to complete its development. Artemia sp. (Branchiopoda, Artemiidae) cyst, a crustacean tested for the laboratory rearing of other hemipteran species, could be used as food, being less expensive than the species commonly employed (Sitotroga cerealella [Olivier] [Lepidoptera: Gelechiidae]). The objective of the present study was to determine nymphal developmental time, nymphal mortality, fertility, and sex ratio of T. cucurbitaceus fed on Artemia sp. cysts. Three diets were used during the rearing of three generations: S. cerealella eggs, Artemia sp. cysts and a mix of both species. The nymphal developmental time (11 to 13 days), nymphal mortality (40 to 66 %), and adult fertility (74 to 101 nymphs / female) were similar for all diets. In all cases, the adults showed a high female proportion (0.67-0.97). In conclusion, Artemia sp. cysts are suitable for T. cucurbitaceus laboratory rearing at least for three generations.

Artemia sp.（Branchiopoda，Artemidae）作为园艺害虫捕食者Tupiocoris cucurbitaceus（半翅目：Miridae）实验室饲养的替代猎物的评估

葫芦蚧（Spinola）（半翅目：Miridae）是一种生活在几个美国国家的白粉虫（半翅目：Aleyrodidae）的捕食者。饲养这种虫子需要使用植物作为产卵基质和猎物来完成它的发育。Artemia sp.（Branchiopoda，Artemidae）囊肿是一种用于实验室饲养其他半翅目物种的甲壳类动物，可以用作食物，比通常使用的物种（Sitotroga cereaella[Olivier][鳞翅目：水母科]）便宜。本研究的目的是确定以卤虫（Artemia sp.）囊肿为食的葫芦若虫的发育时间、若虫死亡率、生育能力和性别比。在三代的饲养过程中使用了三种饮食：蜡状芽孢杆菌蛋、卤虫囊肿和这两种物种的混合物。若虫发育时间（11至13天），若虫死亡率（40至66 %), 所有日粮的成虫生育能力（74至101若虫/雌）相似。在所有情况下，成虫的雌性比例都很高（0.67-0.97）。总之，Artemia sp.包囊适合葫芦T.cucurbitaceus实验室饲养至少三代。
