Abstract Background Insecticidal proteins from the Bacillus thuringiensis ( Bt ) marks genetically modified cotton crop that was commercialized in India March 2002 for control of lepidopteron bollworms. Despite organized initial control, pink bollworm (PBW), Pectinophora gossypiella (Saunders), adapted itself to cry toxins resulted field failures 2016 and 2017. The present study designed unders...

The cotton bollworm Helicoverpa armigera occurs as a major pest in many economically important crops, including cotton, pigeon pea, chickpea, cowpea, sunflower, tomato, sorghum, pearl millet and other crops. Intestinal microorganisms play role the degradation of diet components insects. In order to know gut bacteria insecticide resistance five insecticides Chlorpyriphos (20% EC), Cypermethrin (...

The impact of a tapioca-based artificial diet on the developmental rate, life history parameters, and fertility was examined over five consecutive generations for the cotton bollworm, Helicoverpa armigera Hubner (Lepidoptera: Noctuidae), a highly polyphagous pest of many agricultural crops. The study showed that when fed the tapioca-based artificial diet during larval stage, larval and pupal de...

influence of 13 soybean cultivars (356, m4, m7, m9, clark, sahar, jk, bp, williams, l17, zane, gorgan3 and dpx) on the life table parameters of the cotton bollworm, helicoverpa armigera (hã¼bner) was studied at 25 â± 1â°c, relative humidity of 65 â± 5% and a photoperiod of 16: 8 (l: d) h. the survival rate (lx) of individuals developed to adults from the initial cohort on the mentioned cultivar...

Cluster Frontline Demonstrations using IPM technologies were conducted on farmer fields’ during two consecutive years of both kharif (June-November 2017 and 2018) by Krishi Vigyan Kendra, Kampasagar, Telangana State, India. The results revealed that, 16.9% increased cotton yield was observed in demonstration plot (2234.0 kg ha-1) against farmers practice (1910.5 ha-1). average gross returns, ne...

Abstract Background After the commercialization of insect-resistant transgenic Bt cotton Bollgard I & II, India ranks first in world production. Cotton insecticide consumption was drastically reduced as nearly 95% area replaced with II. However, benefits appear to have been diminished pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae) developed field resistance Cr...
