...rve their action against bollworms. Therefore, the present study has been designed to observe the dual action of transgenic cotton and botanical extracts against pink bollworm during two consecutive growing years (2015 and 2016). The three local extracts such as tobacco (Nicotiana tabacium), neem (Azadirachtin indica) and datura (Datura stramonium) were used in traditional method. The overall results showed that the sprays at...

...te an extensive range of bollworms larvae in both Agricultural and Horticultural crops. Spodoptera litura is a commercial pest of diverse field crops comprising cauliflower (Brassica oleracea var. botrytis). Current inspections were carried out to determine their impact on larval mortality, pupal and adult emergence by exposing three field strains of S. litura (Faisalabad, Chiniot and Sargodha), under laboratory conditions. Both NPV...

...ids, and whiteflies) and bollworms (spotted and pink) were assessed in the experimental field of Nuclear Institute of Agriculture, Tandojam. The experiment was conducted under Randomized Complete Block Design (RCBD) with three replications. The result of overall mean revealed that NIA-M-20 had comparatively greater resistance to the attack of jassids (0.21/leaf) whitefly (0.29/leaf) and thrips (1.63/leaf). Similarly, NIA-M-16 also showed the lowest infestation...

...mental changes on cotton bollworms like Pink Bollworm (PBW), Spotted Bollworm (SBW) and American bollworms (ABW) present in Multan (Southern Punjab), Pakistan. The experimental data was collected from spring 2014 to fall 2016. Eggs and adults count of these bollworms were counted throughout the cropping season. Statistix (Version 8.1) were used to analyzed the data statistically. The mean ...

...y insect pests including bollworms. These pests are controlled by frequent use of pesticides. However, the

indiscriminate use of synthetic pesticides has disturbed agro-ecosystem and costs over US$ 195 million per year to

the nation in terms of environmental and social costs. Pathogenicity and efficacy trials of indigenous

entomopathogenic nematodes (EPNs) isolates have positive results. Four EPN isolates viz., Steinernema

Therefore, the present study was planned to work out the behavior of different cotton cultivars i.e., MNH-1086, WEAL-AG-10, SLH-CHANDI, FH-494, MNH-1050, FH-492, WEAL-AG-9, BH-224, VH-418, SLH-Afnan-II, WEAL-AL-AG-CKC3-01, FH-142, FH-414, RH-KING 20, WEAL-AG-20 1(ii), FH-ANMOL, SLH-55, BH-225, UAM-20, FH-498, and WEAL-AG-11 for insect pest infestation and cotton yield as well as its impact on fiber quality. The cultivars dif...

...he population of spotted bollworms at 1.63, 0.96, 0.89, and 0.84 were counted. Jassid infestation was recorded at 1.24, 1.02, 0.96, 0.93, and whitefly population fluctuations at 1.18, 0.95, 0.83, and 0.79. Overall maximum pest infestation of thrips was recorded at 1.29 compared to spotted bollworms at 1.08, jassid 1.04, and whitefly 0.94, respectively. Present studies are planned to carry out and collect data for the informa...

Relationship Between Damage by Cotton Bollworm Helicoverpa armigera (Hübner) and Different Plant Characteristics of Bt and Non-Bt Cotton Varieties in Pakistan

...rmigera and other cotton bollworms. However, the development of resistance in H. armigera to Bt transgenic cotton varieties is of major concern. This study assessed the H. armigera resistance to Cry1Ac expressing cotton varieties and association of plant biochemical, physico-morphic and physiological traits with boll damage by H. armigera. ELISA results revealed significantly high toxin (Cry1Ac) contents in Bt varieties particularly in PB-38, CRS-456 and PB-89...
