Generation cycles in experimental populations of a multivoltine insect

Journal of Animal Ecology, EarlyView.
Although theory suggests various mechanisms by which environmental and ecological factors may drive generational fluctuations, our field‐cage experiment is the first to demonstrate how internal dynamics and external disturbances jointly produce synchronised, large‐scale outbreak cycles.

Coccinellidae on native and introduced spruce in central Europe: conservation implications in urban areas

Frontiers in Ecology and Evolution
The abundance and species composition of adult ladybird communities (Coleoptera: Coccinellidae) were investigated on two congeneric trees, native Norway spruce (Picea abies) and the introduced blue spruce (Picea pungens), at four locations in Slovakia ...

Ladybird (Coleoptera: Coccinellidae) dispersal in experimental fragmented alfalfa landscapes

European Journal of Entomology, 2005
Habitat fragmentation may affect the dispersal behaviour of individuals across the landscape. If there is a high boundary contrast between the remaining fragments and the matrix, individuals should tend to stay inside the fragments, but the configuration

Transcriptome responses to heat- and cold-stress in ladybirds (Cryptolaemus montrouzieri Mulasnt) analyzed by deep-sequencing

Biological Research, 2015
Changed temperature not only threaten agricultural production, but they also affect individual biological behavior, population and community of many insects, and consequently reduce the stability of our ecosystem.

‘From the Fields Into the Bars’: The Story of Israel's First Transgender Novel, The Cut (1977)

Gender &History, EarlyView.
ABSTRACT In 1977, an Israeli transgender woman, Judy Spotheim, published an autobiographical novel entitled The Cut. It describes the emergence of a trans community in the commercial‐sex areas of Tel Aviv‐Jaffa, hoping to humanise trans women (coccinelles). This article is the first to study the novel and present a biography of Spotheim.

Host plant-mediated prey preference and consumption by an aphidophagous ladybird, Menochilus sexmaculatus (Fabricius) (Coleoptera: Coccinellidae)

Egyptian Journal of Biological Pest Control, 2018
The impact of host plant-aphid combination on the prey consumption and prey preference by adult ladybird, Menochilus sexmaculatus (Fabricius) (Coleoptera: Coccinellidae) was studied, using aphid-prey, Aphis craccivora (Koch) and Lipaphis erysimi (Kalt.),

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Efficiency of three indigenous species of coccinellid predators for controlling aphids and whiteflies on cucumbers in greenhouses

Bioscience Journal
Cucumber plants can be infested with many insect pests such as aphids, whiteflies, and thrips, especially in greenhouses, resulting in significant damage to the crops.

“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

Insect 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.
