“Alien versus predator”: predatory effect of coccinellid Exochomus quadripustulatus on the scale insect Toumeyella parvicornis. An open‐field experimentation on the Pinus pinea of Rome

open access: yesInsect Science, EarlyView.
The release of gravid Exochomus quadripustulatus females proved to be effective in containing Toumeyella parvicornis infestations on stone pine trees, under open‐field condition. The ladybugs caused a lower infestation level compared to the trees that did not receive any ladybugs during the observation season.

Parasitoid development and superparasitism in invasive versus native widow spider host egg sacs

open access: yes, 2023
The brown widow spider, Latrodectus geometricus, is a hazardous and highly invasive species globally. One of the suggested mechanisms enhancing this spider's invasiveness is lower susceptibility to natural enemies compared to other widow species.

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.

Ant–aphid mutualism: the influence of Tapinoma ibericum (Hymenoptera: Formicidae) on Aphis gossypii (Hemiptera: Aphidae) control by commercial and spontaneous natural enemies

open access: yesInsect Science, EarlyView.
The mutualism between Tapinoma ibericum ants and Aphis gossypii disrupts the biological control exerted by Aphidius colemani in greenhouse peppers. Ant exclusion increased parasitism and the presence of most natural enemies, although Aphidoletes aphidimyza was more abundant with ants.

Impact of Cry1AB toxin from transgenic maize (Mon 810) and microbial BT spray (Dipel) on the ecology of a non-target parasitoid, Cotesia marginiventris

open access: yes, 2008
Cry1Ab toxin derived from Bacillus thuringiensis (Bt) has been used for the control of susceptible lepidopteran species throughout the world. Currently, sprayable Bt formulations and transgenic plants have been used for lepidopteran pest control.

Reduced fertilization regimes could boost biocontrol service without reducing crop yield

open access: yesInsect Science, EarlyView.
Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

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,

Egg parasitoid complex of the pine processionary moth in NW Italy

open access: yes, 2023
Investigations on the egg parasitoid complex of the pine processionary moth (PPM), Thaumetopoea pityocampa, were performed in 2020-2022 in seven sites located in NW Italy to determine the parasitoid species composition, seasonal emergence, parasitoid ...

Trichogramma: an egg parasitoid of crop pests

open access: yesBhartiya Krishi Anusandhan Patrika, 2018
Use of insecticides to manage the emerging pest problems in the different crop being taken by farmers in their field. Today, due to indiscriminate use of insecticide, the agriculture produces getting contaminated and traced in food channel. For the reason, many farmers moving towards organic farming to produce pesticide free foods.
