Kairomonal Stimulation of Oviposition into an Artificial Substrate by the Endoparasitoid Microplitis croceipes (Hymenoptera: Braconidae)1

Kairomonal Stimulation of Oviposition into an Artificial Substrate by the Endoparasitoid Microplitis croceipes (Hymenoptera: Braconidae)

Parasitism of a Factitious Host, Galleria Mellonella (lepidoptera: Pyralidae) by an Endoparasitoid: Oviposition and Emergence of Microplitis Croceipes (hymenoptera: Braconidae)

An acquired distaste: sugar discrimination by the larval parasitoid Microplitis croceipes (Hymenoptera: Braconidae) is affected by prior sugar exposure.

We examined gustatory responses of the larval parasitoid Microplitis croceipes to determine whether the adults discriminate among common sugars, including fructose, glucose, maltose and sucrose, found in plants. When given single sugar solutions of sucrose, glucose, fructose and maltose at concentrations of 0.008-2.0 mol l(-1), the estimated concentrations at which 50% of wasps initiated feedin...

Host age preference of Microplitis mediator (Hymenoptera: Braconidae), an endoparasitoid of Mythimna separata (Lepidoptera: Noctuidae)

Microplitis mediator (Haliday) is a solitary endoparasitoid of larvae of the cotton bollworm, Helicoverpa armigera (Hübner) and the oriental armyworm, Mythimna = Leucania separata (Walker). The preference and suitability of different instars of M. separata for M. mediator were determined under laboratory conditions at a constant temperature of 26 ± 1 C, 65 ± 5% RH and L14:D10 photoperiod. The s...

Functional morphology of antennal chemoreceptors of the parasitoid Microplitis croceipes (Hymenoptera: Braconidae).

The specialist parasitoid, Microplitis croceipes (Cresson) (Hymenoptera: Braconidae), uses chemical cues from plants damaged by herbivore-feeding and also plant by-products in host location and acceptance. These chemicals are detected by the wasp's antennae. We conducted scanning and transmission electron microscopy studies of male and female M. croceipes antennae and detected no distinct morph...
