PARASITISM, SEX RATIO, DEVELOPMENTAL TIME AND GREGARIOUSNESS OF ACEROPHAGUS PAPAYAE (HYMENOPTERA: ENCYRTIDAE) ON MALE AND FEMALE HOST STAGES OF PARACOCCUS MARGINATUS IN NO-CHOICE SITUATIONS

open access: yesFUUAST Journal of Biology, 2021
Acerophagus papayae, accidentally introduced parasitoid of Paracoccus marginatus in Malaysia was studied for parasitism, sex ratio, developmental time and gregariousness behaviour. The parasitoid was able to develop in all stages of P.

Life Beneath Silk Walls: A Review of the Primitively Social Embiidina [PDF]

open access: yes, 1997
I review and summarize the scattered information on embiids (Order Embiidina), with an emphasis on details of colony structure and maternal care. I summarize experimental and observational field results from a detailed study on parental and communal ...

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.

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.

Anholocyclic overwintering of Myzus persicae: Host plant selection as a driver for aphid performance and survival

open access: yesAnnals of Applied Biology, EarlyView.
The green peach aphid, Myzus persicae, is the main virus vector in sugar beet. We examine its performance on potential winter hosts as well as the host selection and overwintering success of anholicyclic aphids in order to improve forecasting models for virus outbreaks through targeted monitoring of suitable winter hosts. Abstract Virus yellows (VY) is

Residual Effects of New Insecticides on Egg and Nymph Densities of Bemisia tabaci (Hemiptera: Aleyrodidae)

open access: yes, 2013
The residual effects of 4 new insecticides (cyazypyr, flupyradifurone, pyrifluquinazon, and sulfoxaflor) and 2 registered insecticides (pymetrozine and a combination of zeta-cypermethrin and bifenthrin) on egg and nymph densities of Bemisia tabaci ...

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 ...

Understanding climate-sensitive tick development and diapause with a structured population model

open access: yesFrontiers in Veterinary Science
IntroductionTick-borne diseases have become a growing public health concern globally. As climate change reshapes the environment, tick populations are expected to expand into previously unsuitable areas, further increasing human exposure to ticks and the
