Development of the European Ladybirds Smartphone Application: A Tool for Citizen Science

Frontiers in Ecology and Evolution, 2021
Wildlife observations submitted by volunteers through citizen science initiatives are increasingly used within research and policy. Ladybirds are popular and charismatic insects, with most species being relatively easy to identify from photographs ...

Differences in the phenology of Harmonia axyridis (Coleoptera: Coccinellidae) and native coccinellids in Central Europe [PDF]

, 2019
Harmonia axyridis (Pallas), an invasive non-native species in central Europe, can outcompete other aphidophagous species. The distribution and abundance of H.

Population dynamics of aphid and coexisting predators in tomato agroecosystem

Journal of Agrometeorology, 2021
Aphids generally attack vegetative plant parts, preferably leaves, and devitalize the plant by sucking the cell sap. Thorough knowledge of pest-predator ecology and their interaction is requisite to initiate timely pest management strategies ...

Functional response of the predator Eriopis connexa (Coleoptera: Coccinellidae) to different prey types

Brazilian Archives of Biology and Technology, 2007
This work evaluated the functional response of adult females of Eriopis connexa to different densities of Macrosiphum euphorbiae and Tetranychus evansi. When preying upon aphids, E. connexa presented a sigmoidal functional response (Type III).

Urbanization filters coccinellids composition and functional trait distributions in greenspaces across greater Santiago, Chile [PDF]

, 2019
Urbanization alters community composition, frequently leading to decline in native species abundance and richness. Nevertheless, responses might also depend on trait-based local habitat and landscape-scale filters.

Effects of habitat loss and fragmentation on the abundance and species richness of aphidophagous beetles and aphids in experimental alfalfa landscapes

European Journal of Entomology, 2008
In agro-ecosystems, habitat loss and fragmentation may alter the assemblage of aphidophagous insects, such as foliar-foraging (coccinellids) and ground-foraging predators (carabids), potentially affecting intraguild interactions. We evaluated how habitat

“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.

Reduced fertilization regimes could boost biocontrol service without reducing crop yield

Insect 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.

Abundance of Coccinellids and Their Potential Prey in Field-Crop and Grass Habitats in Eastern South Dakota [PDF]

, 2018
A rich fauna of coccinellids occurs in eastern South Dakota, but the abundance of some species has declined in association with the establishment of an exotic lady beetle, Coccinella septempunctata (L.) (Coleoptera: Coccinellidae), in the mid-1980s.

An updated checklist of the ladybird beetles (Col., Coccinellidae) of Nepal [PDF]

Journal of Insect Biodiversity and Systematics
The checklist of ladybird beetles in the coleopteran family Coccinellidae of Nepal includes 219 species belonging to 12 tribes and 55 genera. They are distributed from a wide elevation range from 81 m to 4500 m asl.
