Web architecture alteration of the orb web weaving spider Metellina merianae (Araneae, Tetragnathidae) induced by the parasitoid Megaetaira madida (Ichneumonidae, Polysphincta group)

Arachnologische Mitteilungen, 2016
The polysphinctine wasp Megaetaira madida (Haliday, 1838) is a koinobiont ecto-parasitoid of spiders of the genus Metellina. Under the influence of the parasitoid’s final instar larva, the spider host M. merianae (Scopoli, 1763) built a three-dimensional

The impact of tree mortality and post‐disturbance management on insect diversity in temperate forests: Insights from a replicated experiment

Journal of Applied Ecology, EarlyView.
Our experiment provides strong evidence for the importance of clustered tree mortality for comprehensive insect diversity in temperate forests and highlights the potential of forest management to enhance insect diversity in homogeneous commercial forests, particularly through the creation of canopy gaps and the retention of deadwood. Both mimic natural

Biological Flora of Britain and Ireland: Cytisus scoparius*

Journal of Ecology, EarlyView.
Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.

First detection of Ixodiphagus hookeri (Hymenoptera: Encyrtidae) in Ixodes ricinus ticks (Acari: Ixodidae) from multiple locations in Hungary

Scientific Reports, 2023
The parasitoid wasp, Ixodiphagus hookeri (Hymenoptera: Encyrtidae), is the natural enemy of a wide range of hard and soft tick species. While these encyrtid wasps are supposed to be distributed worldwide, only a few studies report on their actual ...

Biological invasion by the cycad‐specific scale pest Aulacaspis yasumatsui (Diaspididae) into Cycas revoluta (Cycadaceae) populations on Amami‐Oshima and Okinawa‐jima, Japan

Plant Species Biology, EarlyView.
This article details the invasion of cycad aulacaspis scale into the islands of Okinawa‐Jima and Amami‐Oshima. Several recommendations are proposed in this article by members of the IUCN cycad specialist group and experts in the biological control of this scale insect.

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

Insect 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.

Biological control of the chestnut gall wasp with \emph{T. sinensis}: a mathematical model [PDF]

arXiv, 2015
The Asian chestnut gall wasp \emph{Dryocosmus kuriphilus}, native of China, has become a pest when it appeared in Japan, Korea, and the United States. In Europe it was first found in Italy, in 2002. In 1982 the host-specific parasitoid \emph{Torymus sinensis} was introduced in Japan, in an attempt to achieve a biological control of the pest.

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

Insect 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.

Global redistribution and local migration in semi-discrete host-parasitoid population dynamic models [PDF]

arXiv, 2019
Host-parasitoid population dynamics is often probed using a semi-discrete/hybrid modeling framework. Here, the update functions in the discrete-time model connecting year-to-year changes in the population densities are obtained by solving ordinary differential equations that mechanistically describe interactions when hosts become vulnerable to ...

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

arXiv, 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.
