Life‐History Traits and Overwintering of Actia interrupta (Diptera: Tachinidae), a Larval Parasitoid of Choristoneura fumiferana (Lepidoptera: Tortricidae)

Entomologia Experimentalis et Applicata, EarlyView.
Actia interrupta is a larval tachinid parasitoid that plays a key role in regulating low‐density populations of the eastern spruce budworm. We describe its immature stages, life‐history traits, host‐searching behavior, development, and confirm its larviparous reproductive strategy.

Parasitic wasp‐associated polydnavirus and venom affect arthropod community assembly on wild cabbage via the caterpillar host

Ecological Entomology, EarlyView.
Cotesia glomerata polydnavirus and venom, either alone or in combination, affect colonisation by members of the arthropod community in a natural field setting. Plants damaged by P. brassicae injected with both polydnavirus and venom were colonised more often by Mamestra brassicae caterpillars, Myzus persicae aphids and aphid parasitoids compared to ...

Electrophysiological activity of the Sirex noctilio ovipositor: You know the drill?

, 2015
Sirex woodwasp (Sirex noctilio F: Hymenoptera: Siricidae) is a major worldwide pest of pine (Pinus) species. The female woodwasp undertakes exploratory drills with the ovipositor prior to egg-laying to assess tree suitability.

Maternal factors from a parasitoid wasp mediate hyperparasitoid attraction to parasitized caterpillars

Ecological Entomology, EarlyView.
The parasitoid‐associated polydnavirus CgPDV, but not venom alone, significantly increases the attractiveness of Pieris brassicae caterpillars to the hyperparasitoid Baryscapus galactopus at close range. Naturally parasitized caterpillars elicit stronger hyperparasitoid attraction than any injection treatment, indicating that additional factors beyond ...

Ultramorphology of the ovipositor of Venturia canescens (Gravenhorst) and possible mechanisms for oviposition

, 2012
Morphology, ultrastructure and possible mechanics of the ovipositor of Venturia canescens (Gravenhorst) (Hymenoptera: Ichneumonidae) is described using scanning and transmission electron microscopy. The ovipositor of V. canescens consisted of three pairs

Thermal acclimation and environment drive field dispersal patterns of adult Mediterranean fruit flies

Ecological Entomology, EarlyView.
Ambient temperature significantly increased Mediterranean fruit fly recapture rates, demonstrating a strong effect of immediate environmental conditions on field dispersal. Female recaptures were 2.6‐fold higher in orchards containing host plants, whereas male recaptures were unaffected by host presence.

Neuromuscular Anatomy and Motor Patterns at the Base of Calling Behaviour in the Female Spongy Moth Lymantria dispar

Insects
“Calling behaviour” is a stereotyped rhythmic motor pattern displayed by female moths, by which they emit the sex pheromone to attract of conspecific males.

Female genitalia as a taxonomic tool in the classification of Indian Acridoidea (Orthoptera)

Journal of Threatened Taxa, 2011
A comparative study on female genitalia was carried out in Indian species of the superfamily Acridoidea. An attempt has been made to describe and illustrate the different structures viz., spermatheca, ovipositor, sub genital plate, supra-anal plate and ...

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

First Record of Arrhenophagus chionaspidis Aurivillius (Hymenoptera: Encyrtidae) Parasitizing White Mango Scale in Kenya: Its Potential Distribution and Prospects in Biocontrol

Journal of Applied Entomology, EarlyView.
ABSTRACT The white mango scale, Aulacaspis tubercularis Newstead (Hemiptera: Diaspididae), is one of the most destructive pests of mango worldwide. Its current management in most of the invaded areas largely depends on the intensive use of chemical insecticides.
