Bemisia tabaci; biotypes; cotton; cryptic species; cytochrome-c oxidase; genetic markers; geographical distribution; mitochondria; pest management; pests; population dynamics; sympatry; vegetables; Benin; Burkina Faso; East Asia
Abstract:
... Bemisia tabaci Gennadius is a major pest on cotton and vegetable plants in Africa. It is considered as a cryptic species complex. Identification of the most damaging species such as the Middle East–Asia Minor 1 (B biotype) and Mediterranean (MED) (which contains the Q and Africa silverleaf (ASL) biotypes) species represents an important step towards the management of B. tabaci. Some data on the ge ...

Abstract:
... Lysiphlebus testaceipes (Cresson) (Hymenoptera: Braconidae, Aphidiinae) is a newly discovered species alien to Benin (West Africa) and the dominating aphid primary parasitoid in vegetable agroecosystems. A study on the preference of this parasitic hymenopteran for three key aphid pests of vegetables (Aphis craccivora Koch, Aphis gossypii Glover and Lipaphis erysimi (Kaltenbach) (Homoptera: Aphidid ...

Abstract:
... Experiments were conducted in the laboratory to screen the leaf extract of Dracaena arborea (Willd.) Link for the presence of chemical groups with insecticidal activity against Sitophilus zeamais (Motsch.) and Callosobruchus maculatus (Fab.). The plant materials were collected, dried, ground to fine powder and extracted with 90% ethanol. Phytochemical screening involved the use of thin layer chrom ...

Abstract:
... Indian siris, Albizia lebbeck (L.) Benth., is a useful tree that is being widely planted for shade in the Ahwaz region of southwest Iran. The tree is, however, severely attacked by the citrus red mite Eutetranychus orientalis Klein. Seasonal population dynamics of the mite were investigated on A. lebbeck in Ahwaz during 2010–2011. Eutetranychus orientalis had two population peaks on A. lebbeck. Th ...

Abstract:
... With the advent of transgenic Bacillus thuringiensis (Bt)-cowpea, there is a need to identify the feeding preferences of Maruca vitrata Fab. to determine in which component of the plant the expression of the toxin needs to be the highest to ensure the greatest efficacy of insecticidal Bt proteins. In the current study, we examined the feeding preferences of M. vitrata larvae in a naturally infeste ...

Abstract:
... In the present study, we aimed to assess the suitability of predatory parameters, namely voracity, consumption index, conversion efficiency and growth rate, as measures of prey suitability. For this purpose, fourth-instar larvae and 10-day-old adult females of four co-occurring ladybirds, namely Coccinella septempunctata (L.) (C7), C. transversalis F., Cheilomenes sexmaculata (F.) and Propylea dis ...
