Effects of timed LED regimes on tomato plant traits, performance of two‐spotted spider mites, and predatory mites (Phytoseiulus persimilis)

open access: yesPest Management Science, Volume 81, Issue 4, Page 2300-2311, April 2025.
Light‐emitting diode (LED)‐based treatments for enhancing crop production and pest management have primarily focused on continuous treatments. This study, using Tetranychus urticae and Phytoseiulus persimilis, demonstrates that the timing of LED supplementation is crucial for designing integrated pest management strategies that improve both plant ...

Effect of the nutritional quality of primary food on the development, sex ratio, and size of a parasitoid in a quadri-trophic food web

open access: yesEuropean Journal of Entomology, 2023
This study explores the effect of nutritional composition on the fitness of consumers in a quadri-trophic food web. Specifically, we studied how enrichment of the food of fruit flies Drosophila melanogaster (Meigen, 1830) transfers to the spider ...

Indirect plant defense may provide economically important pest suppression in sorghum

open access: yesPest Management Science, EarlyView.
Laboratory measures of sorghum direct and indirect plant resistance traits aligned with natural enemy recruitment and pest suppression in the field. Abstract BACKGROUND A promising strategy to optimize biological control of insect pests is selecting crop varieties with indirect defense traits.

Monte Carlo Simulation of Age-Dependent Host-Parasite Relations [PDF]

open access: yes, 2007
The death of a biological population is an extreme event which we investigate here for a host-parasitoid system. Our simulations using the Penna ageing model show how biological evolution can ``teach'' the parasitoids to avoid extinction by waiting for the right age of the host. We also show the dependence of extinction time on the population size.

WASP-147b, 160Bb, 164b and 165b: two hot Saturns and two Jupiters, including two planets with metal-rich hosts [PDF]

open access: yes2019, MNRAS, 482, p.301-312, 2018
We report the discovery of four transiting hot Jupiters, WASP-147, WASP-160B, WASP-164 and WASP-165 from the WASP survey. WASP-147b is a near Saturn-mass ($M_P = 0.28 M_{J}$) object with a radius of $ 1.11 \, R_{J}$ orbiting a G4 star with a period of $ 4.6 $ d.

Effect of vermicompost on functional response of the parasitoid wasp Aphidius colemani (Hym., Braconidae) to the melon aphid, Aphis gossypii (Hem., Aphididae) [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2017
Changing of host plant quality via agricultural practices such as application of fertilizer may influence the behavioral traits of natural enemies. In this study, the effect of improving cucumber plants with different vermicompost: soil ratios (0:100 ...

Modeling parasitoid development: climate change impacts on Telenomus remus (Nixon) and Trichogramma foersteri (Takahashi) in southern Brazil

open access: yesPest Management Science, EarlyView.
Phenological models revealed temperature‐driven development variability in Telenomus remus and Trichogramma foersteri, highlighting potential impacts of climate change on their biological control efficacy in warmer and colder regions. Abstract BACKGROUND The egg parasitoids Telenomus remus (Nixon) and Trichogramma foersteri (Takahashi) were recently ...

Side effects of pesticides used in organic and conventional tomato crops on Dolichogenidea gelechiidivoris, a parasitoid of Tuta absoluta

open access: yesPest Management Science, EarlyView.
This study reveals strong variability in the effects of eight tomato integrated pest management‐compatible pesticides on Dolichogenidea gelechiidivoris, identifying harmful compounds such as spinosad and more selective ones such as sulfur and spiromesifen, depending on the exposure route.

Chaotic dynamics of the sugarcane borer-two parasitoid agroecosystem with seasonality [PDF]

open access: yesarXiv, 2022
Sugarcane production is a significant and profitable agribusiness sector in many countries. Nevertheless, this industry suffers significant losses from the sugarcane pests, among which the most important one is the sugarcane borer (Diatraea saccharalis).

Generalist predators function as pest specialists: Examining diet composition of spiders and ladybeetles across rice crop stages

open access: yesJournal of Applied Ecology, EarlyView.
By quantifying the diet composition of GAPs over crop stages, farm types and years, this study reveals that generalist predators have potential to produce a stable, predictable top‐down effect on pests in rice agro‐ecosystems. Therefore, promoting the field densities of ubiquitous generalist predators will likely enhance pest management and support ...
