BACKGROUND Species of Eretmocerus Haldeman develop as primary ecto-endoparasites of whiteflies (Rose and Rosen 1992). Currently, the genus Eretmocerus comprises 86 species worldwide, of which 11 species have been previously recorded from Taiwan (Shih et al. 2015). Despite having been recently revised for Taiwan, two new species are here added to the Taiwan fauna. NEW INFORMATION Two new speci...

An extensive survey of predatory Coccinellid beetles (Coleoptera: Coccinellidae) was conducted in the Chitral District, Pakistan, over a period of 7 months (April through October, 2001). A total of 2600 specimens of Coccinellids were collected from 12 different localities having altitudes from 1219.40–2651.63 m. Twelve different species belonging to 9 genera of 3 tribes and 2 sub-families were ...

The dynamics of the composition populations Adalia bipunctata L. in St. Petersburg and Yalta (Crimean Peninsula) for 4732 years has been studied. proportion black individuals them decreased by almost 2 times. Comparison with climatic features habitats (average annual temperature) showed that population negatively correlates average temperature previous year. observed change geographically remot...

The ability of a natural enemy to tolerate a wide temperature range is a critical factor in the evaluation of its suitability as a biological control agent. In the current study, temperature-dependent development of the two-spotted ladybeetle A. bipunctata L. (Coleoptera: Coccinellidae) was evaluated on Myzus persicae (Sulzer) (Hemiptera: Aphididae) and a factitious food consisting of moist bee...

The prediction of pest-control functioning by multi-predator communities is hindered by the non-additive nature of species functioning. Such non-additivity, commonly termed an emergent multi-predator effect, is known to be affected by elements of the ecological context, such as the structure and composition of vegetation, in addition to the traits of the predators themselves. Here we report mes...

Bu çalışma, Erzurum (Atatürk Üniversitesi Kampüsü)’da 2016 ve 2017 yıllarının mayıs-eylül ayları arasında Karaağaç (Ulmus glabra Hudson) bitkisinde yoğun olarak zararına rastlanan Tinocallis (sappocallis) saltans (Nevsky, 1929) (Hemiptera: Aphididae)’ın popülasyon değişimi predatörlerini tespit etmek amacıyla yürütülmüştür. Türkiye’de bu karaağaç türü üzerinde T. ilk kez çalışma ile belirlenmiş...
