The evolutionary effects of crowding on male courtship behavior were studied using wild and mass-reared medflies. Mass-reared strains had been raised under highly crowded conditions in mass-rearing facilities for approximately 75, 180, and 238 generations. Pre-mounting courtship was facultatively shortened in both wild and mass-reared males under conditions of greater crowding. The courtship be...

In this study we describe the structure and composition of ant communities in the endemic Moroccan Argan forest, using pitfall traps sampling technique throughout the four seasons between May 2006 and February 2007. The study focused on two distinct climatic habitats within the Essaouira Argan forest, a semi-continental site at Lahssinate, and a coastal site at Boutazarte. Thirteen different an...

Variation in diet can influence the timing of major life-history events and can drive population diversification and ultimately speciation. Proximate responses of life histories to diet have been well studied. However, there are scant experimental data on how organisms adapt to divergent diets over the longer term. We focused on this omission by testing the responses of a global pest, the Medit...

Ceratitis capitata (Wiedemann), başta turunçgiller olmak üzere birçok meyve türünde önemli bir dış karantina zararlısıdır. Bu çalışma, 2016-2019 yılları arasında Çanakkale’de yürütülmüştür. Akdeniz sineğinin popülasyon değişimlerini tespit etmek amacıyla kayısı bahçelerine Trimedlure içeren delta tipi feromon tuzaklar yerleştirilmiştir. Çalışma sonucunda, popülasyonunun 2016 ve 2018 yıllarında ...

Symbiosis in fruit flies (Dipt.: Tephritidae), despite its long history of study, is still a relatively poorly understood aspect of the life history of these insect pests (reviewed by Drew and Lloyd 1991; Lauzon 2003). Many tephritid species are uniquely adapted for housing large quantities of bacteria in their digestive tract (the oesophageal bulb in adults and gastric caeca in larvae) and som...

Studies were conducted in Honduras to determine effective sampling range of a female-targeted protein-based synthetic attractant for the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae). Multilure traps were baited with ammonium acetate, putrescine, and trimethylamine lures (three-component attractant) and sampled over eight consecutive weeks. Field design consiste...

Forced infestation studies were conducted to determine whether northern or southern highbush blueberries, Vaccinium corymbosum L., are hosts for the invasive tephritid fruit flies in Hawaii. Fruit were exposed to gravid female flies of Bactrocera dorsalis Hendel (oriental fruit fly), Ceratitis capitata (Wiedemann) (Mediterranean fruit fly), or Bactrocera cucurbitae Coquillet (melon fly) in scre...

Basil oil and its three major active constituents (trans-anethole, estragole, and linalool) obtained from basil (Oscimum basilicum L.) were tested on three tephritid fruit fly species [Ceratitis capitata (Wiedemann), Bactrocera dorsalis (Hendel), and Bactrocera cucurbitae (Coquillett)] for insecticidal activity. All test chemicals acted fast and showed a steep dose-response relationship. The le...

The digestive system of Ceratitis capitata was characterized during its larval development and in the insect stage. Disaccharidases against maltose and sucrose were more evident in the 2nd and 3rd day of larval development and in the adult stage, respectively. Glycosil-hydrolyses with higher specific alpha-galactosidasic and beta-galactosidasic activities were detected in the 2nd and 3rd day of...
