Bioactivity of Locally Available Plants on Cotton Whitefly, Bemisia tabaci and the fungus isolated from cotton

Bioactivity of Indigenous Medicinal Plants against the Cotton Whitefly, Bemisia tabaci

Forty-one methanol extracts of 28 indigenous medicinal plant species were tested for their insecticidal bioactivity against cotton whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), adults and second nymphal instars under controlled conditions. This study is within a bioprospection context, in the form of utilizing local plant species as an alternative in sustainable agriculture dev...

Efficacy of Some Insecticides Against Whitefly (Bemisia tabaci Genn.) Infesting Cotton under Field Conditions

Seven insecticides, viz. Megamos 20SL, Actara 25WG, Polo 500SC, Sitara 25WP, Nighaban 20EC, Thiodan 35EC and Confidor 200SL were evaluated at their field recommended doses for their efficacy against whitefly (Bemisia tabaci Genn.) on cotton, at the farmer’s field in Dera Ghazi Khan during 2007. The insecticides were applied at ETL’s of whitefly. All the test insecticides caused significant mort...

DNA Barcoding of Bemisia tabaci Complex (Hemiptera: Aleyrodidae) Reveals Southerly Expansion of the Dominant Whitefly Species on Cotton in Pakistan

BACKGROUND Although whiteflies (Bemisia tabaci complex) are an important pest of cotton in Pakistan, its taxonomic diversity is poorly understood. As DNA barcoding is an effective tool for resolving species complexes and analyzing species distributions, we used this approach to analyze genetic diversity in the B. tabaci complex and map the distribution of B. tabaci lineages in cotton growing ar...

pathogenicity of beauveria bassiana and lecanicillium muscariumon cotton whitefly(bemisia tabaci (homoptera: aleyrodidae)) in simultaneously use

pathogenicity of beauveria bassiana strain debi001, lecanicillium muscarium strain daom 198499 and their combination was investigated on 2nd nymphs and adults of b. tabaci in lab condition (in a germinator, 23±1ºc, 95±5% and 16:8 l:d). five concentrations of each fungi were sprayed on undersides of young eggplant leaves that involved 2nd nymphs. experiments were carried out on adults with the s...
