Tachinid parasitoids: are they to be considered as koinobionts?

摘要: Tachinids are usually considered as koinobionts none of them kills or paralyzes the host when first entering it. These parasitoids, however, do not fit well into koinobiont/idiobiont dichotomy because only some species show a high degree physiological adaptation to host, whereas larvae other grow quickly following attack and kill rapidly, thus behaving more idiobionts. The in vitro rearing technique provides further evidence for poor adequacy tachinids. In fact, while typical known be difficult culture on artificial media, tachinids displaying non-synchronized development with have been successfully reared insect material-free similarly I therefore suggest use classification class instead basis presence absence developmental synchrony their hosts.
