Comparison of nonchemical, organic and synthetic Varroa destructor control strategies in honey bee colonies: effects on parasite load, colony strength and health

open access: yesPest Management Science, EarlyView.
Combining intensive drone‐brood removal with brood interruption provided the most effective and consistent seasonal Varroa control. Abstract BACKGROUND Varroa destructor remains the most significant biotic threat to honey bee colonies, and increasing resistance to synthetic acaricides necessitates alternative control strategies.

Patterns and Mechanisms of Niche Partitioning Between Related Parasitoids (Hymenoptera) Sharing the Same Host Species

open access: yesInsects
Related species of parasitoid Hymenoptera often coexist on a certain host, but many details of interactions between these organisms remain unclear. The present review summarizes the main existing concepts and facts and suggests principal patterns and ...

Erythro-6-Acetoxy-5-hexadecanolide, the major component of a mosquito oviposition attractant pheromone

open access: yes, 1982
The major component of the oviposition attractant pheromone from the apical droplet of eggs of the mosquito Culex pipiens fatigans is shown by g.l.c.–mass spectrometry, microchemical methods, and synthesis to be erythro-6-acetoxy-5-hexadecanolide (1 ...

The potential global distribution of Drosophila suzukii, including consideration of irrigation and Australian host cropping areas

open access: yesPest Management Science, EarlyView.
This CLIMEX model of Drosophila suzukii fits the global distribution very well and includes irrigation effects. It indicates that D. suzukii could threaten all Australian berry and cherry production areas if introduced. Abstract BACKGROUND Spotted wing drosophila, Drosophila suzukii (Matsumura), is a major fruit fly pest of cherries and berries across ...

The functional significance of fruit exocarp on host selection and oviposition by Queensland fruit fly, Bactrocera tryoni (Froggatt) (Tephritidae: Diptera) [PDF]

open access: yes, 2014
Queensland fruit fly is Australia's most serious insect pest of horticulture. The fly lays its eggs into fruit, where they hatch into maggots which destroy the fruit.

Proteo‐transcriptomic insights into the venom composition of the ectoparasitoid Eupelmus urozonus

open access: yesPest Management Science, EarlyView.
Integrated venom‐gland transcriptomics and venom proteomics of Eupelmus urozonus identified 316 venom proteins, including 75 secreted candidates, revealing diverse hydrolases, proteases/inhibitors and many uncharacterized effectors. Abstract BACKGROUND Ectoparasitoid venoms are ‘cocktails’ of bioactive molecules injected during oviposition to paralyze ...

Genetic variation for oviposition behavior inDrosophila melanogaster. II.:Oviposition preferences and differential survival

open access: yes, 1990
Several behavioral traits connected with oviposition were studied inDrosophila melanogaster strains which had been kept on regular and ethanol-supplemented food. All strains preferred food with a low agar content for oviposition, though this tendency was
