Macrolophus pygmaeus Rambur (Hemiptera: Miridae) is a generalist predatory
mirid widely used in augmentative biological control of various insect
pests in greenhouse tomato production in Europe, including the invasive
tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera, Gelechiidae).
However, its biocontrol efficacy often relies on the presence of
alternative prey. The present study aimed at evaluating the effect of
various prey foods (Ephestia kuehniella eggs, Bemisia tabaci nymphs, Tuta
absoluta eggs and Macrosiphum euphorbiae nymphs) on some life history
traits of M. pygmaeus. Both nymphal development and adult fertility of M.
pygmaeus were significantly affected by prey food type, but not survival.
Duration of nymphal stage was higher when M. pygmaeus fed on T. absoluta
eggs compared to the other prey. Mean fertility of M. pygmaeus females was
greatest when fed with B. tabaci nymphs, and was greater when offered M.
euphorbiae aphids and E. kuehniella eggs than when offered T. absoluta
eggs. Given the low quality of T. absoluta eggs, the efficacy of M.
pygmaeus to control T. absoluta may be limited in the absence of other
food sources. Experiments for assessing effectiveness of generalist
predators should involve the possible impact of prey preference as well as
a possible prey switching.
Data_brutIn this data, we have developmment and survival of Macrolophus
pygmaeus feed on different prey.We measured also the fertility of females
Macrolophus rearing on these prey.Data_analysesThis is summary data used
for statistical tests.
