Parasitoid foraging and oviposition behavior in the field
Since parasitoids can be reared from their hosts and leave evidence of parasitism after they emerge from hosts, some general outlines of their foraging behavior can be inferred from field studies that do not involve direct observation. However, direct observations are often needed to uncover critical aspects of patch use, host finding, and host use. Studies of parasitoid foraging in the field u...

Testing the habituation assumption underlying models of parasitoid foraging behavior
BACKGROUND Habituation, a form of non-associative learning, has several well-defined characteristics that apply to a wide range of physiological and behavioral responses in many organisms. In classic patch time allocation models, habituation is considered to be a major mechanistic component of parasitoid behavioral strategies. However, parasitoid behavioral responses to host cues have not previ...
متن کاملthe effect of competition on foraging behavior of a thelytokous parasitoid, lysiphlebus fabarum (marshall) on aphis fabae scopoli
abstract competition is a phenomenon that influences the size, structure and stability of insect communities, particularly on solitary endoparasitoids species. although, competition normally incurs costs, it might be adaptive for the surviving individual. to determine which factors affect the patch use strategy of foragers under competition, the effect of previous experience with hosts already-...
متن کاملthe effect of experience and age on foraging behavior of a thelytokous parasitoid, lysiphlebus fabarum (marshall) on aphis fabae scopoli
abstract parasitic insects face many decisions when foraging for host, some for example frequently have to make decisions with regard to staying in or leaving their current patch. in this study, we investigated how the foraging and oviposition behavior of lysiphlebus fabarum is influenced by (1) a female’s previous experience of encountering aphids host and (2) age of female parasitoids. to tes...
