Beyond adult models: Tribolium castaneum larval timekeeping reveals unexpected robustness and insights into circadian clock

open access: yesInsect Science, EarlyView.
Abstract Circadian rhythms are self‐sustained endogenous oscillations that are found in all living organisms. In insects, circadian rhythms control a wide variety of behavioral and physiological processes, including feeding, locomotion, mating, and metabolism.

Two new species of Oobius Trjapitzin (Hymenoptera, Encyrtidae) egg parasitoids of Agrilus spp. (Coleoptera, Buprestidae) from the USA, including a key and taxonomic notes on other congeneric Nearctic taxa

open access: yesZooKeys, 2015
Oobius Trjapitzin (Hymenoptera, Encyrtidae) species are egg parasitoids that are important for the biological control of some Buprestidae and Cerambycidae (Coleoptera). Two species, O. agrili Zhang & Huang and O.

Host-feeding enhances stability of discrete-time host-parasitoid population dynamic models [PDF]

open access: yesarXiv, 2015
Discrete-time models are the traditional approach for capturing population dynamics of a host-parasitoid system. Recent work has introduced a semi-discrete framework for obtaining model update functions that connect host-parasitoid population levels from year-to-year.

On a Hyperbolic-Parabolic Parasitoid-Parasite System: Well Posedness and Control [PDF]

open access: yesarXiv, 2020
We develop a time and space dependent predator-prey model. The predators' equation is a non local hyperbolic balance law, while the diffusion of prey obeys a parabolic equation, so that predators "hunt" for prey, while prey diffuse. A control term allows to describe the use of predators as parasitoids to limit the growth of prey-parasites.

Host Sex Discrimination by an Egg Parasitoid on Brassica Leaves

open access: yesJournal of Chemical Ecology, 2011
Egg parasitoids are able to find their hosts by exploiting their chemical footprints as host location cues. In nature, the apolar epicuticular wax layer of plants that consists of several classes of hydrocarbons serves as the substrate that retains these contact kairomones. However, experiments on chemical footprints generally have used filter paper as

Egg Paeasitoids of Dalbulus maidis (Hemiptera: Cicadellidae) in Jalisco State, Mexico [PDF]

open access: yes, 2009
A survey of eggs parasitoids of the corn leafhopper, Dalbulus maidis (DeLong & Wolcott) was conducted in Jalisco State, Mexico. Samples were collected during the summer of 2008 with sentinel eggs.

Effect of Spiroplasma infection on the mating behavior of Glossina fuscipes fuscipes

open access: yesInsect Science, EarlyView.
Abstract Tsetse flies are insects of significant public health and zoonotic importance as they are the main vectors of African trypanosomes. To date, an effective vaccine is unavailable and efforts to limit the spread of the disease primarily rely on controlling the tsetse populations.

Spatial and Temporal Heterogeneity of Host-Parasitoid Interactions in Lupine Habitat [PDF]

open access: yesarXiv, 2008
The inhabitants of the bush lupine in coastal California have been the subject of scientific scrutiny in recent years. Observations of a host-parasitoid interaction in the shrub's foliage, in which victims are significantly less motile than their exploiters, record stable spatial patterns in a fairly homogeneous environment.

Stress in dipteran insects mass‐reared for sterile insect technique applications

open access: yesInsect Science, EarlyView.
The connections between biotic and abiotic stress affecting mass‐reared dipteran insects and the associated stress and immunological responses. Numbers indicate the order in which the topics are discussed in this review. Abstract Stress may be viewed as the disturbance of homeostasis of an organism.

Effects of Bacillus thuringiensis subsp. kurstaki HD1 spore-crystal mixture on the adults of egg parasitoid Trichogramma evanescens (Hymenoptera: Trichogrammatidae)

open access: yes, 2015
In the present study, the potential hazard of Bacillus thuringiensis (Bt) kurstaki HD1 spore-crystal mixture (spore/δ-endotoxin) on parasitization performance and longevity of female egg parasitoid Trichogramma evanescens Westwood was evaluated. For this
