Background & Aim: The plants of the greenhouse have been affected by infestation of the pest Trialeurodes vaporariorum, called greenhouse whitefly, which markedly reduced production. Synthetic insecticides have been widely developed and, their extensive use has brought about disadvantages, like environmental disturbance, pest resistance, lethal effects on non target organisms ...

background : mosquitoes transmit serious human diseases, causing millions of death every year. vector control is facing a threat due to the emergence of resistance to synthetic insecticides. insecticides of botanical origin may serve as suitable alternative biocontrol techniques in the future. nine different locally available medicinally important plants suspected to posse larvicidal property w...

INTRODUCTION The aim of the present study was to analyze the larvicidal activity of different crude extracts of Larrea cuneifolia and its most abundant lignan, nordihydroguaiaretic acid (NDGA), against Culex quinquefasciatus. METHODS Chloroform, methanol, and aqueous extracts from L. cuneifolia and NDGA were tested against larvae of Cx. quinquefasciatus under laboratory conditions. RESULTS ...

Bark of Rhamnus dispermus Ehrenb (Rhamnaceae) was collected from Ash-Shoubak, Jordan, and extracted with hexane, chloroform, acetone and ethanol, respectively. The aim of this study was to test the insecticidal activity of these extracts against the peach trunk aphid (PTA), Pterochloroides persicae (Homoptera: Lachnidae), since it has been shown that Rhamnus spp. may contain compounds that can ...

Pest insects can damage agricultural crops, consume and/or damage harvested food, or transmit diseases to humans and animals. The past 30 years has witnessed a dramatic reemergence of epidemic vector-borne diseases throughout much of the world (Atkinson, 2010).
