Fig. 27.—Cocoon of Campoplex phtho- rimaeae, parasite of potato tuber moth. Much enlarged. (Original.) mean temperature of about 54 HABROBRACON JOHANNSENI VIER.^ This is probably the best known parasite of the tuber moth, both where it occurs as a leaf-miner and as a pest of stored potatoes. It is wcU distributed, having been reared from tuber-moth material"collected over most of southern Cahfomia. It oviposits in the mature larva of the tuber moth after it has spun its cocoon. As many as 13 parasite liirvsc have been observed to develop on a single host. The adult female is very active, })ut seems to prefer to work oidy in the light, for the parasite has never been resired from material k(!pt in darkened bins. The larvaj may develop eitJier ext(irnally or internally, the host seeming to depend on the position of the egg. Aft(!r the tuber-moth. Fig. 2S.—Campo- plex phihorimaeae: Lateral view of pupa.
