Host Sex Discrimination by an Egg Parasitoid on Brassica Leaves

open access: yesJournal of Chemical Ecology, 2011
Egg parasitoids are able to find their hosts by exploiting their chemical footprints as host location cues. In nature, the apolar epicuticular wax layer of plants that consists of several classes of hydrocarbons serves as the substrate that retains these contact kairomones. However, experiments on chemical footprints generally have used filter paper as

Rainfall shapes the physiological condition, but not the body size, of an introduced dung beetle in Brazilian pastures

open access: yesEcological Entomology, EarlyView.
Understanding rainfall‐driven physiological shifts in dung beetles is crucial to predict how climate change may affect the fitness and persistence of key insect species in tropical pastures. We compared body size, dry, lipid and muscle masses of Digitonthophagus gazella collected during dry and rainy seasons in Brazilian pastures to assess the effects ...

Efisiensi pemarasitan parasitoid Trichogramma chilotraeae nagaraja & nagarkatti (Hymenoptera:Trichogrammatidae) pada berbagai jumlah inang dan kepadatan parasitoid.

open access: yesJurnal Entomologi Indonesia, 2017
The objective of the research was to study behaviour and parasitism efficiency of the egg parasitoid Trichogramma chilotraeae in relation to host and parasitoid density under laboratory condition.

Reduced Fecundity Associated with Wolbachia Infection in a Neotropical Drosophilid Redução da fecundidade associada à infecção por Wolbachia em um Drosofilídeo Neotropical

open access: yesEcological Entomology, EarlyView.
Using multiple infected and uninfected Drosophila sturtevanti lines, we investigated (i) the impact of Wolbachia on fecundity and (ii) its effects relative to antibiotic treatment. Based on over 1680 dissected ovaries, fecundity was similar between infected and uninfected flies.

Plant architecture and vegetation structure: Two ways for insect herbivores to escape parasitism

open access: yesEuropean Journal of Entomology, 2008
Interactions between herbivorous insects and their parasitoids occur in highly structured and complex environments. Habitat structure can be an important factor affecting ecological interactions between different trophic levels.

Temperature Effects on Development of Three Cereal Aphid Parasitoids (Hymenoptera: Aphidiidae) [PDF]

open access: yes, 2017
Temperature is an important climatological variable that influences the biology and ecology of insects. Poor climatic adaptation can limit the effectiveness of parasitic insects in biological control.

Using citizen science as a research prioritization tool to detect co‐occurrences of the invasive species Harmonia axyridis

open access: yesInsect Conservation and Diversity, EarlyView.
We studied co‐occurrences and potential novel interactions between the invasive ladybird Harmonia axyridis and local biota (plants, arthropods and fungi) across Argentina using citizen science records. We detected co‐occurrences (mainly Asteracea and Aphididae) and previously unreported interactions (predation, parasitism, interspecific mating and ...

Natural Enemies of Cranberry Fruitworm, \u3ci\u3eAcrobasis Vaccinii\u3c/i\u3e, (Lepidoptera: Pyraudae) in Michigan Highbush Blueberries [PDF]

open access: yes, 2017
A two-year study was conducted in Michigan highbush blueberries to determine the complex of parasitoids attacking cranberry fruitworm, Acrobasis vaccinii. Eight parasitoid species and one fungal pathogen were collected.

Toward a global repository of insect traits (GRIT)

open access: yesInsect Conservation and Diversity, EarlyView.
Biodiversity loss is accelerating, yet insect conservation is hindered by the absence of a centralised, comprehensive trait database. We propose the GRIT, a FAIR, open‐access platform uniting datasets and collaborators worldwide. GRIT will harness advanced computational tools for trait acquisition and imputation, enabling large‐scale ecological ...

Floral resource strips enhance parasitoid abundance and diversity in apple orchards and promote agroecological advances in a South African biosphere reserve

open access: yesInsect Conservation and Diversity, EarlyView.
Floral resource strips within apple orchards increased parasitoid abundance and influenced community composition, enhancing local biodiversity in the Kogelberg Biosphere Reserve's transition zone. Ruderal and natural fynbos habitats supported higher parasitoid richness and abundance, emphasising the importance of conserving semi‐natural habitats ...
