Beschreibungen/Notizen

• Host acceptance and parasitization of the warehouse beetle, Trogoderma variabile Ballion, by the ectoparasitic wasp Laelius pedatus (Say) were affected by host developmental stage and size. Larvae <2.5 mm long or 0.4 mg in weight were not parasitized, although a few were paralyzed. Clutch size was positively correlated with host size but was limited on large hosts by the finite number of mature eggs available for oviposition. The maximal clutch size was six eggs during a 1-d exposure and nine eggs when the host(s) was exposed for 3 d. Female wasps showed no host size preference in a choice test. Inexperienced females 3-7 d after emergence produced either 0 or one male progeny per clutch, and never was more than one male offspring per host observed.
