“…and is considered the most noxious pest of the cotton. 5-45% of yield losses are caused by sucking complex as reported by Ahuja et al (2009). The usage of insecticides which are improper and non-selective causes resistance in insects.…”

The parents MCU 5, CO 14, CO 17, TCH 1828, KC 2, KC 3, GISV 323, GTHV 15–34 and RHC 1409 of upland cotton were used for the present study. They were obtained from the Tamilnadu Agricultural University, Department of cotton, Coimbatore. Among the 27 primers used only JESPR 154 primer showed amplified fragment at 150 bp which validates the corresponding parents with hairiness trait conferring resistance to Jassid. The hairy nature of trichome density was observed among the resistant genotypes (KC 3, GTHV 15–34, GISV 323 and RHC 1409). Hairiness confers resistance to jassids was evidence from the results and discussion which would confer breeders develop varieties with high resistance genotypes thereby reducing the jassid infestation. The trichomes were found to confer resistance to sucking pests. This henceforth reduce the pesticide consumption in cotton plants thereby paving the way for a safety environment for ecological species without harming them. Pesticide usage would be lowered with the use of tolerant genotypes. It also paves way for the improvement of future integrated pest management (IPM) programme.

“…As most organic cotton cultivation in India is under rain-fed conditions special emphasis should be put on the breeding of the neglected cotton species G. arboreum as an interesting source for natural pest and drought resistance considering the required fiber length of the textile industry. However, as the field selection is very time and resource consuming it would also be interesting to perform genome wide association studies for the different pests to pave the way for MAS, and to check for cytoplasm effects on bollworm tolerance [36]. Breeding for pest resistance gains importance for GM cotton as well.…”

Extent of Bollworm and Sucking Pest Damage on Modern and Traditional Cotton Species and Potential for Breeding in Organic Cotton

et al. 2019

Resistance against cotton bollworm is one of the main arguments for the use of genetically modified (GM) Bt cotton around the globe. The use of GM is prohibited in organic systems and thus the remunerative value of organic cotton cultivation depends on effective bollworm control. In this study, we investigated the extent of bollworm and sucking pest damage in 68 different hybrid and varietal lines of Gossypium hirsutum and varietal lines of G. arboreum at two different locations with contrasting soil fertility and water dynamics. The damage potential of bollworms was assessed from open capsules at two time points. Sucking pests were assessed at three time points using a scoring method. G. arboreum varietal lines and G. hirsutum hybrids were on average significantly more tolerant than G. hirsutum varietal lines to bollworm under fertile and irrigated situations. For sucking pests, the G. arboreum varietal lines were clearly more tolerant than G. hirsutum hybrids and varietal lines. Since, recently, pink bollworm (Pectinophora gossypiella) became resistant against Bt cotton and pressure of sucking pests severely increased, screening of genetic resources and systems-based cotton breeding for bollworm and sucking pest tolerance will improve sustainability of organic and conventional cotton production.
