This is especially true for those that are idiobiont parasitoids with a synovigenic egg load (as A.
Host plant quality or size is commonly correlated to parasitoid fitness, especially in idiobiont parasitoids, whose offspring may depend on the quality and size of the host at the time of oviposition (Gols and Harvey, 2008; Fortuna et al., 2012).

When parasitoids were found on larvae, they were further categorized as idiobiont (suspending leafminer development) ectoparasitoid, idiobiont endoparasitoid, or koinobiont endoparasitoid (allowing continued development of the leafminer host before eventual host death).
Idiobiont parasitoids paralyze the host before ovipositing, and their offspring develop in limited resources.
According to Wang & Messing (2004), for parasitoids, the success of the offspring development is strongly influenced by the female's choice of the most suitable host, especially for idiobiont ectoparasitoids such as T.
The ichneumonid wasp Pimpla nipponica is a solitary idiobiont endoparasitoid attacking a variety of lepidopteran pupae [17-19] and is one of the species that show different abdominal tip movements, which enable predicting the sex of eggs that the female decides to lay [16].
Furthermore, individuals removed from the population at an early stage by predators or idiobiont parasitoids (that kill or permanently paralyze the host during oviposition) are unavailable to natural enemies at later stages, whereas diseased immatures and those parasitized by koinobiont parasitoids (that permit continued host development following oviposition) may remain in the population for some time and be eaten by predators or killed by some non-enemy factor.
