“…The highest population of jassid was observed during 46 th MW (5.76 jassids/3 leaves). The trends of jassid infestation were more or less similar to those reported by earlier researchers like Patel and Radalia (2018) [17] who reported that the cotton jassid was observed throughout the cropping period during both seasons. The peak population of jassid was recorded in 43 rd MW (37.22 jassids/3 leaves) and 46 th MW (38.48 jassids/3 leaves) during 2015-16 and 2016-17, respectively.…”

A field experiment conducted over Kharif seasons of 2020 and 2021 at All India Coordinated Cotton Improvement Project, MPKV, Rahuri, examined the impact of weather factors on sucking pest populations in Bt cotton. The data reveal that aphids were predominant, ranging from 4.60 to 120.86/3 leaves in 2020 and 0.64 to 63.60/3 leaves in 2021. Jassids ranged from 2.04 to 11.46/3 leaves in 2020 and 0.52 to 5.76/3 leaves in 2021. Thrips ranged from 0.26 to 13.78/3 leaves in 2020 and 0.18 to 57.46/3 leaves in 2021. Whiteflies varied from 0.24 to 8.32/3 leaves in 2020 and 0.04 to 5.82/3 leaves in 2021 with peak activity recorded in the 42 nd SMW of 2020 and the 46 th SMW of 2021. Natural predators like lady bird beetles, green lace wings and predatory spiders were observed throughout the cropping season, showing peak activity in specific weeks.

“…1101-2 BG II were on par with it whereas, higher incidence was recorded on VBCH 1545 BG II (7.61 per 3 leaves). Patel and Radadia [20] recorded peak population of jassid in the susceptible cotton cultivar GSB-21 i.e. 37.22 jassids/3 leaves and 38.48 jassids/ 3 leaves during kharif seasons of 2015-16 and 2016-17, respectively.…”

Host plant resistance is an important component of integrated pest management strategy for jassid resistance. Evaluation of germplasm to identify the stable source of resistance is a predominant step in any resistance breeding programme. In this study, screening of Gossypium hirsutum cotton varieties/genotypes against jassid, Amrasca biguttula biguttula (Ishida) was carried out under rainfed conditions during kharif seasons of 2016-17, 2018-19 and 2019-20 at Regional Cotton Research Station, Navsari Agricultural University, Maktampur farm, Bharuch, Gujarat. Among thirteen cotton varieties/genotypes screened, none of variety/genotype was categorized as resistant by considering jassid population as well as Jassid Resistance Index. Six cotton varieties/genotypes viz., NH-615, GBHV-201, GBHV-209, GBHV-204, G.N.Cot-26, GBHV-206 and two checks i.e. DHY-286 and NDLH-1938 were categorized as moderately resistant based on maximum jassid population ranged from 4.40 to 7.40 jassids/3 leaves. Three cotton varieties/genotypes viz., Suraj, Bunny BG II and Bunny Non Bt were categorized as susceptible with population of 12.50 to 13.70 jassids/3 leaves. The cotton variety G.Cot-16 (16.70 jassids/3 leaves) and check DCH-32 (24.60 jassids/3 leaves) were categorized as highly susceptible to jassids. Five cotton varieties/genotypes viz., NH-615, GBHV-201, GBHV-204, GBHV-209, G.N.Cot-26 and two checks i.e. DHY-286 and NDLH-1938 were categorized as moderately resistant based on maximum Jassid Resistance Index in range of 1.10 to 2.00. Only the genotype GBHV-206 was found susceptible with 2.20 JRI. Four cotton varieties/genotypes viz., G.Cot-16, Bunny BG II, Suraj, Bunny Non Bt and check DCH-32 were categorized as highly susceptible to jassid based on maximum JRI of 3.10 to 4.00. Overall five varieties/genotypes of G. hirsutum cotton viz., NH-615, GBHV-201, GBHV-209, GBHV-204 and G.N.Cot-26 were found moderately resistant to jassids under rainfed conditions.

Various insect pests can damage crops to different extents, reducing both their quality and quantity. Cotton and sugarcane are particularly vulnerable to sucking complex pests and borer complex pests, which cause damage in different ways. Complex pest sucking sap from delicate plant components, while borer complex pests bore into the crop. These pests have the potential to cause significant damage to the agricultural sector, leading to a considerable loss in yield and quality. The haphazard use of insecticides and pesticides to manage these pests has become a global problem, resulting in harmful effects on human health, plant systems, and the environment. To regulate pest populations, different integrated pest management techniques are followed, including physical, mechanical, cultural, and biological methods. These strategies, which are both sustainable and environmentally sound, attempt to keep pest populations below the economic threshold level. This paper gives an introduction to the invasive pest, biology, lifecycle, and integrated management of cotton and sugarcane pests.
