Local adaptation at fine spatial scale through chromosomal inversions and mito-nuclear epistasis: Findings in Drosophila subobscura (Diptera: Drosophilidae)

European Journal of Entomology, 2019
To explore local adaptation in wild populations at a fine spatial scale we characterized the genetic variability of eight closely located populations of Drosophila subobscura and its associations with microhabitat environmental conditions.

Rhythmic oscillations of α-amylase protein and its enzymatic activity levels in Drosophila melanogaster (Diptera: Drosophilidae)

European Journal of Entomology, 2009
In this report, we show that α-amylase activity is rhythmic in the wild-type fruit fly Drosophila melanogaster, and that this rhythm exhibits the properties of a clock output. Moreover, the rhythm of amylase activity is accompanied by fluctuations in the

Development of an eco‐friendly RNAi yeast attractive targeted sugar bait that silences the shaker gene in spotted‐wing drosophila, Drosophila suzukii

Pest Management Science, EarlyView.
This study discusses a promising new attractive targeted sugar bait (ATSB) technology using yeast that expresses shRNA targeting essential genes in the fruit pest spotted‐wing drosophila (SWD). The yeast, which is delivered using soda as a sugar bait, could one day be an effective component in integrated SWD control programs.

Texture features explain the susceptibility of grapevine cultivars to Drosophila suzukii (Diptera: Drosophilidae) infestation in ripening and drying grapes

Scientific Reports, 2020
Grapevine is a well-known host plant of the invasive pest Drosophila suzukii, but its susceptibility to pest oviposition and development greatly depends on the cultivar.

Winter fruit contribution to the performance of the invasive fruit fly Drosophila suzukii under different thermal regimes

Insect Science, EarlyView.
Highlights: The contribution of winter and early spring‐available fruit (Aucuba japonica, Elaeagnus ×submacrophylla, and Viscum album) to the performance of D. suzukii depended on their P:C ratio and biophysical properties Even though D. suzukii performance was the lowest in A.

An unexpected discovery of the drosophilid fy Gitona distigma Meigen, 1830 (Diptera: Drosophilidae) in the nests of the sand martin Riparia riparia (Linnaeus, 1758), with notes on morphology and distribution [PDF]

Кавказский энтомологический бюллетень
During excavations of the nests of the sand martin Riparia riparia (Linnaeus, 1758), large numbers of adults of the drosophilid fy Gitona distigma Meigen, 1830 (Diptera: Drosophilidae) were found.

Morphometric criteria to differentiate Drosophila suzukii (Diptera: Drosophilidae) seasonal morphs

PLoS ONE, 2020
Temperate insect species often enter diapause in preparation for overwintering. One such species is the invasive vinegar fly, Drosophila suzukii (Matsumura), which has seasonal polymorphisms, considered winter and summer morphs.

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

Insect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Occurrence of invasive species and seasonal dynamics of fruit flies (Diptera: Drosophilidae) species in Uşak province, Turkey

, 2020
In Turkey, studies on Drosophilidae species, which are not considered agriculturally harmful, have not been deepened about their presence, diversity and seasonal population changes, until Drosophila suzukii began to spread worldwide. As a result of this,

Temperature is a common climatic descriptor of lachryphagous activity period in Phortica variegata (Diptera: Drosophilidae) from multiple geographical locations

Parasites & Vectors, 2020
The drosophilid Phortica variegata is known as vector of Thelazia callipaeda, the oriental eyeworm native to Asia that has become an emergent zoonotic agent in several European regions.
