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.

Impact of Host and Food Availability on Life‐History Traits in Six Egg Parasitoid Species of the Genus Trichogramma

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...

Prey Range and Voracity of Main Insect Natural Enemies of Pests in Corsican Clementine Orchards

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
To assess the biocontrol potential on the main arthropod pests of clementine orchards in Corsica, laboratory experiments were carried out using five potential predators. Their prey range and voracity were tested on three pest species. Then, a global predation rate index was calculated at the scale of the entire community of insect predators.

Comparative genetic studies of native and introduced Coccinellidae in North America

open access: yesEuropean Journal of Entomology, 2005
During the past four decades, several species of aphidophagous Coccinellidae became established in North America, including Coccinella septempunctata, Harmonia axyridis, Hippodamia variegata, and Propylea quatuordecimpunctata.

Plant Traits and Reproduction in a Multitrophic System: The Role of Aphids, Parasitoids and Hyperparasitoids

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
This field mesocosm study examined the top‐down effects of hyperparasitoids, parasitoids and aphids on plant growth and fitness. Parasitoids reduced aphid populations, but this effect was attenuated by hyperparasitoids. However, these multitrophic interactions did not affect plant traits and reproduction, likely due to the plant's fast life cycle and ...

Induction of reproductive diapause in Hippodamia convergens (Coleoptera: Coccinellidae) hinges on prey quality and availability

open access: yesEuropean Journal of Entomology, 2005
In the High Plains of western Kansas, USA, the convergent lady beetle Hippodamia convergens Guérin completes a spring generation feeding on cereal aphids in winter wheat before leaving fields in large numbers around the time of harvest.

First record of Serangium montazerii (Coleoptera: Coccinellidae): A new exotic predator of Aleurocanthus spiniferus (Hemiptera: Aleyrodidae) in Greece

open access: yesEPPO Bulletin, EarlyView.
Abstract The biodiversity of Greek agroecosystems is constantly changing, with the influx of new species reshaping food webs. The present study contributes to the documentation of Greek fauna by reporting, for the first time, the occurrence of the Asian predatory ladybird Serangium montazerii Fürsch (Coleoptera: Coccinellidae). The species was detected

The influence of female oviposition strategy on sibling cannibalism in the ladybird beetle Harmonia axyridis (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2003
I hypothesized that sibling cannibalism is one of maternal investment in that a female controls sibling cannibalism. To test the hypothesis, I conducted a laboratory experiment and field observations to investigate sibling cannibalism in relation to ...
