An endoparasitoid avoids hyperparasitism by manipulating immobile host herbivore to modify host plant morphology. [PDF]

PLoS ONE, 2014
Many parasitic organisms have an ability to manipulate their hosts to increase their own fitness. In parasitoids, behavioral changes of mobile hosts to avoid or protect against predation and hyperparasitism have been intensively studied, but host ...

Diversity of Parasitoids Hymenoptera in Agricultural Ecosystems and Primary Forest in Lubuk Kilangan District, Padang

Andalasian International Journal of Entomology, 2023
Parasitoid Hymenoptera is an important natural enemy of most plant pests, and it can control pests specifically in the agricultural ecosystem. The study aimed to study parasitoid Hymenoptera diversity in agricultural and primary forest ecosystems. The research was conducted from March to June 2018 at Lubuk Kilangan Subdistrict, Padang.

A molecular detection approach for a cotton aphid-parasitoid complex in northern China

Scientific Reports, 2019
Aphid-parasitoid interactions have been widely used as a model system in research studies on the structure and functions of arthropod food web. Research on aphid-parasitoid food webs is hindered by their micromorphological characteristics and the high ...

An Effector TaCRVP From Tuta Absoluta Oral Secretion Impairs H2O2‐Mediated Plant Defense by Targeting Tomato SlCAT2

Advanced Science, EarlyView.
The Tuta absoluta salivary effector TaCRVP subverts tomato immunity by hijacking host catalase SlCAT2. Through a sophisticated dual mechanism, TaCRVP simultaneously promotes SlCAT2 tetramerization for activation and blocks its SlAdBiL‐mediated degradation for stabilization.
