Lebensdauer des räuberischen Marienkäfers Serangium parcesetosum Sicard (Col., Coccinellidae) mit natürlicher und künstlicher Nahrung [PDF]

, 2008
The little known ladybird, Serangium parcesetosum SICARD (Col., Coccinellidae) seems to be an important predator of whiteflies. It has found attacking Bemisia tabaci (GENN.) (Hom., Aleyrodidae) (KAPADIA & PURI 1992), Aleurolobus barodensis MASK (PATEL et

Towards an attract‐and‐reward strategy: evaluating nectar resources and HIPVs under laboratory conditions to enhance Aphelinus mali parasitism activity, a key parasitoid of Eriosoma lanigerum

Pest Management Science, EarlyView.
Euphorbia segetalis is a promising attractant insectary plant for Aphelinus mali. Meanwhile, Vicia faba and Vicia sativa are a promising nectar resource to sustain the parasitoid in early spring when the population of Eriosoma lanigerum is low, and honeydew is scarce.

Molecular phylogeny reveals food plasticity in the evolution of true ladybird beetles (Coleoptera: Coccinellidae: Coccinellini)

BMC Evolutionary Biology, 2017
BackgroundThe tribe Coccinellini is a group of relatively large ladybird beetles that exhibits remarkable morphological and biological diversity. Many species are aphidophagous, feeding as larvae and adults on aphids, but some species also feed on other ...

Heating up parasitoid–host interactions: High temperature increased mortality of late‐instar braconid larvae and reduced ladybird recovery rate

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract With ongoing climate change, temperature‐dependent outcomes of host–parasitoid interactions can affect ecosystem functioning and key ecosystem services such as biological control. However, most studies addressing the impacts of temperature on host–parasitoid systems are

Unconditioned and conditioned responses to colour in the predatory coccinellid, Harmonia axyridis (Coleoptera: Coccinellidae)

European Journal of Entomology, 2000
We determined if mature ladybirds use colour to initially find suitable host plants. We also determined whether ladybird beetles are capable of associating characteristics such as colour with the presence of prey.

A preventive strategy for the control of aphids in sweet pepper using lacewings and micrococcinelid beetles

Insect Science, EarlyView.
Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

Life table parameters of the pseudococcid predators Nephus includens and Nephus bisignatus (Coleoptera: Coccinelidae)

European Journal of Entomology, 2007
The fecundity of the pseudococcid predators Nephus includens (Boheman) and N. bisignatus (Kirsch) (Coleoptera: Coccinellidae), fed on Planococcus citri Risso (Hemiptera: Pseudococcidae), was studied at several constant temperatures (15, 20, 25, 30, 32.5 ...

Effect of Dietary Protein and Carbohydrates on Survival and Growth in Larvae of the Henosepilachna vigintioctopunctata (F.) (Coleoptera: Coccinellidae)

Journal of Insect Science, 2018
The ratio of protein and carbohydrate in an insect’s nutritional regime can significantly influence its survival, growth, and fecundity. The effects of 11 different artificial diets containing protein (p): carbohydrate (c) ratios were determined in ...
