Effects of a host tree on movement and distribution of winter geometrid moths (Lepidoptera): thickness of trunks and branches

Folia Oecologica, 2019
Adult moths from an ecological group of winter geometrid species look for trees where they copulate and females lay eggs. We investigated how tree trunk and lower branch thickness affects the occurrence of females on trunks and branches and how the ...

Forests and climate change - lessons from insects

iForest - Biogeosciences and Forestry, 2008
The climate change may indirectly affects the forest ecosystems through the activity of phytophagous insects. The climate change has been claimed to be responsible of the range expansion northward and upward of several insect species of northern ...

Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems

Entomologia Experimentalis et Applicata, EarlyView.
We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

Biology of the Gall Midge Spanolepis selloanae (Diptera, Cecidomyiidae), a Candidate Biological Control Agent of the Invasive Grass Cortaderia selloana

Entomologia Experimentalis et Applicata, EarlyView.
Spanolepis selloanae (Diptera, Cecidomyiidae) infests Cortaderia selloana (pampas grass). It lays eggs in the spikelets, where larvae feed on female parts. The high prevalence of the midge and its combined impact in seed production, condition and viability strongly reduces the reproductive output of C. selloana.

Plant Growth and Arthropod Assemblage Metrics on Sapindus saponaria Fertilized With Dehydrated Municipal Sewage Sludge

Entomologia Experimentalis et Applicata, EarlyView.
Under the conditions evaluated, dehydrated municipal sewage sludge increased branches per plant and ground cover in Sapindus saponaria and increased cumulative arthropod observations and species richness in selected groups. Exploratory multivariate patterns did not demonstrate direct causal plant–arthropod relationships.

Species Composition of Phytophagous and Entomophagous Insects and Mites on Soybeans in Krasnodar and Stavropol Territories, Russia

Agronomy
Soybeans are a valuable crop in many countries of the world. To obtain stable yields, it is necessary to consider the activities of arthropods, both beneficial and destructive. The results of this study indicate high biodiversity.

Evaluating insect-host interactions as a driver of species divergence in palm flower weevils

Communications Biology, 2020
de Medeiros and Farrell test how insect-host interactions influence species divergence in phytophagous insects. Using ddRAD-seq data and hierarchical modelling, they demonstrate, surprisingly, that antagonistic interactions between insect and host do not

Genome assembly of Elcysma westwoodi provides insights into host‐plant cyanogenic glucoside detoxification and chemical defence gene evolution

Insect Molecular Biology, EarlyView.
A chromosome‐level genome of Elcysma westwoodi was assembled. The genome encodes 272 detoxification‐related genes. A single‐copy bCAS was retained for cyanide detoxification. CYP405A and CYP332A were recruited into cyanogenic defence evolution. UGT33A retained a conserved GT‐B fold and catalytic domains.

Food as a factor determining the physiological state of populations of the phytopagous pests of agricultural crops

Овощи России
Relevance. Trophic relationships along with competition and mutualism are the most basic and significant interactions in ecosystems. To develop, survive, and multiply, insects need to consume a certain amount of nutrients at a certain ratio.

Assessment of Small‐Scale Laboratory Rearing Systems for Frankliniella occidentalis (Western Flower Thrips) Using a Single Female

Journal of Applied Entomology, EarlyView.
ABSTRACT Reliable laboratory rearing of Frankliniella occidentalis is critical for experimental consistency in entomological research. This study validates and optimises three small‐scale rearing systems initiated from a single female thrips using various organic fruits, flowers and pollen as feed, along with moist cotton, blotting paper and ...
