Bu çalışmanın amacı 2020-2021 yılları bahar ve yaz aylarında Çanakkale ili meyve bahçelerindeki yumuşak sert çekirdekli ağaçları yabancı otlarda beslenen yaprakbitleri (Hemiptera: Aphididae) üzerindeki predator syrphid türlerinin (Diptera: Syrphidae) belirlenmesidir. Toplamda 6 cinse bağlı türü 15 yaprakbiti tespit edilmiştir. En yaygın türleri 9 üzerinde belirlenen Episyrphus balteatus de Geer...

Higher cyclorrhaphan flies including Drosophila develop a single extraembryonic epithelium (amnioserosa), which closes the germband dorsally. In most other insects two extraembryonic epithelia, serosa and amnion, line the inner eggshell and the ventral germband, respectively. How the two extraembryonic epithelia evolved into one is unclear. Recent studies have shown that, in the flour beetle Tr...

Two experiments were performed in the laboratory to understand the relationships between oviposition preference and larval performance of the two predatory hoverfly species, Episyrphus balteatus de Geer and Metasyrphus corollae Fabricius. We first conducted laboratory experiments to understand the nature and relative strengths of intraguild predation between the larvae of three ladybird species...

Black elder (Sambucus nigra L.) commonly occurs throughout the country – it can be found in forests, thickets, parks, balks or in home gardens. It is a valuable reservoir of food for beneficial insects and a place of refuge or wintering. Almost every part of the elderberry plant has some uses: the fruits, flowers, leaves, roots, pith and bark. Its fruits and flowers are used in herbal medicine ...

To cope with pathogen and insect attacks, plants develop different mechanisms of defence, in both direct (physical and chemical) and indirect ways (attractive volatiles to entomophagous beneficials). Plants are then able to express traits that facilitate “top-down” control of pests by attracting herbivore predators. Here we investigate the indirect defence mechanism of potato plants by analyzin...
