Analysis of a negative binomial host–parasitoid model with two maturation delays and impulsive resource input

open access: yesJournal of Biological Dynamics, 2019
To study the interaction of parasitoids and their insect hosts in laboratory environment, we propose a mathematical model incorporating impulsive resource inputs, stage-structure, maturation times and negative binomial distribution of parasitoid attacks.

Differential Nest Parasitism in Three Sympatric Social Wasps (Hymenoptera: Vespidae: Polistes spp.) in the West Indies

open access: yesSociobiology, 2015
Jamaica's three species of social wasps were found nesting together in a suburban area.  Their nests gave evidence of markedly different parasitoid loads in the sequence Polistes crinitus > P. dorsalis > P. major.  Based on larval and pupal silk remains,

The value of regeneration for insect fauna associated with leaf litter in the Brazilian savanna: A comparative study of biomass and trophic structure

open access: yesAnnals of Applied Biology, EarlyView.
This study demonstrates the ecological value of natural regeneration in the Brazilian Cerrado by analysing the biomass, richness and trophic structure of leaf litter insects across pasture (P), regenerating (R) and native (N) areas. We found that R areas supported insect communities more similar to N habitats than to Ps, with higher richness, greater ...

Observation on the host parasitoid interaction between Periplaneta americana, the American cockroach and Tetrastichus hagenowii, an oothecal parasitoid

open access: yesMemorias do Instituto Oswaldo Cruz, 1994
Investigations were carried out on the host parasitoid interaction between Periplaneta americana, the American cockroach and Tetrastichus hagenowii, an oothecal parasitoid. This gregarious female parasitoid infected and or oviposited in only one host and

Studi keberadaan hiperparasitoid dalam mempengaruhi perilaku imago parasitoid pada kutudaun, Aphis gossypii (Hemiptera: Aphididae)

open access: yesJurnal Entomologi Indonesia, 2017
Study Hyperparasitoid Existing Affected to Adul Parasitoid Behavior on Aphid, Aphis gossypii (Hemiptera: Aphididae). In general, hyperparasitoid is needed for establishing food and chain webs, but in contrary, it could become a limiting factor in ...

State of the spread of the exotic parasitoid wasp Leptopilina japonica tracking the route of its invasive host fly Drosophila suzukii in France

open access: yesAgricultural and Forest Entomology, EarlyView.
To document the current distribution of Leptopilina japonica in France and compare its genetic background, we collected wild fleshy‐fruited plants and cultivated cherries from 11 sites across different regions. The fruits were collected from the canopy. We calculated the percentage of emerging individuals of L.

Degree of insecticide exposure and access to nectar impact survival of Trissolcus japonicus, a hymenopteran parasitoid, in flowering border strips

open access: yesAgricultural and Forest Entomology, EarlyView.
We applied three thiamethoxam spray treatments to buckwheat border strips: control (no nearby spray), drift (adjacent peach trees directly sprayed) and direct spray (buckwheat and peaches directly sprayed). Drift‐treated buckwheat received about 1.4% the amount of thiamethoxam as direct‐spray buckwheat. This amount has no lethal effects on parasitoids,

Plant Domestication Affects the Oviposition Behavior and Performance of Ganaspis kimorum, a Parasitoid of Drosophila suzukii

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
In this study, we investigated the effects of blueberry domestication on the oviposition behavior and performance of Ganaspis kimorum, a parasitoid of Drosophila suzukii. Domestication of blueberries reduced the oviposition‐searching behavior of the parasitoid but enhanced parasitoid performance, including offspring performance. Additionally, blueberry
