The genus Helopeltis (Hemiptera: Miridae) includes some of the major pests of cashew (Anacardium occidentale L. [Anacardiaceae]). Helopeltis species severely damage tender shoots, inflorescences, immature cashew nuts and associated cashew apples (pseudocarps). In India cashew crop losses of more than 40% caused by Helopeltis species are often reported. One of ...

Leptoglossus occidentalis (Heidemann, 1910) and Cydalima perspectalis (Walker, 1859) are alien insect species which have invaded Turkey. Leptoglossus occidentalis was recorded for the first time in Istanbul (Turkey) in 2009 and Cydalima perspectalis was recorded there for the first time in 2011. We examined the distribution of these two invasive ...

The behavioral inhibitory effect of methanol extracts from neem leaves (Azadirachta indica A. Juss) at different concentrations (0, 10,000, 18,000, 32,000 and 56,000 ppm) was evaluated using naive and experienced medflies (Ceratitis capitata (Wied.)) ovipositing on the fruits of grape cv. 'Italia'. The grapes were immersed in the specific treatments ...
