Effects of diet on development and reproductive fitness of two predatory coccinellids (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2015
Studies of prey suitability are needed to develop efficient mass rearing programs for generalist predators and to understand their potential contribution to integrated pest management.

RNA interference of the ecdysone receptor gene AgEcR in a wolfberry ‐ specialized strain of Aphis gossypii Glover affects its survival and fecundity and confers resistance in transgenic goji (Lycium barbarum L.)

open access: yesPest Management Science, EarlyView.
AgEcR, an ecdysone receptor from Aphis gossypii, is an RNA interference (RNAi) target. Artificial diet screening of five double ‐ stranded RNA fragments identified dsAgEcR2 targeting the D/E junction as the most potent. Transgenic goji expressing dsAgEcR2 caused molting defects and reduced fecundity, suppressing population growth and offering a ...

Influence of different species of aphid prey on the immature survival and development of four species of aphidophagous coccinellids (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2015
This study was on the effect of three species of aphids (Aphis fabae, Macrosiphoniella sanborni, Brevicoryne brassicae) on the survival, growth and development of the immature stages of the aphidophagous coccinellids Coccinella septempunctata ...

Impact of Environmental Microparticles on Insect Olfaction

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Coccinellidae captured in blacklight traps: Seasonal and diel pattern of the dominant species Harmonia axyridis (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2013
Two blacklight traps were operated in a non-agricultural setting in Cary, North Carolina, USA, from spring through fall in 2004 and 2005 and all Coccinellidae collected and identified.

Interactions between prairie dogs and arthropods in grassland ecosystems: a review and research gaps

open access: yesWildlife Biology, EarlyView.
Prairie dogs (Cynomys spp.) are an important component of grassland ecosystems of North America where they can alter vegetation composition/structure and physical attributes of grassland habitats through their feeding and burrowing behavior. Impacts of prairie dog presence on many wildlife and plant taxa have been widely studied but research on prairie

Identification of limonene as a potential kairomone of the harlequin ladybird Harmonia axyridis (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2010
Chemical cues involved in both host location and oviposition by Harmonia axyridis Pallas (Coleoptera: Coccinellidae) were investigated in laboratory and field experiments.

Elevated nitrogen deposition protects an invasive plant from herbivory through altering leaf volatile‐mediated tritrophic interactions

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Atmospheric nitrogen deposition disrupts plant–herbivore interactions, but its impact on leaf volatile organic compounds (VOCs)‐mediated multi‐trophic herbivore resistance remains unclear within the context of plant invasion. In this study, we initially investigated the

Ladybird Coccinella septempunctata (Coleoptera: Coccinellidae) prefers toxic prey in laboratory choice experiment

open access: yesEuropean Journal of Entomology, 2008
In a laboratory experiment, we investigated the preference of larvae and adults of Coccinella septempunctata (Coleoptera: Coccinellidae) for three aphid species: two essential prey, Acyrthosiphon pisum and Aphis philadelphi, and a toxic prey Aphis ...
