The egg of the cotton bollworm, which is small and inconspicuous hatches into larvae. The larvae tunnels into large squares or bolls and completes the development in one structure. During this period, the larvae will shed off its skin four to five times. Mature larvae then pupate in bolls, stems or surface. The whole cycle takes place in about six weeks.
cotton bollworm, pink bollworm, thrips, cotton square borer, cotton aphids, whiteflies, fleahoppers, boll weevils, and many other occasional pests
bollworm, pink bollworm, lygus bug
Boll weevils are harmful to the cotton plant. Also birds and Spiders are harmful to them. White flies cover the cotton balls in a sticky liquid called "honeydew" that is expensive to get off. They also suck the sap out of them. Bollworm, pink bollworm, and lygus bug are some more.
The Boll weevil is the best known example - see related link for more details. Also bollworm, pink bollworm, and lygus bugs are serious problems.
Bollworm refers to the larvae of certain moth species, primarily the cotton bollworm (Helicoverpa zea), which is a significant pest in agriculture, particularly in cotton, corn, and soybean crops. These larvae feed on the flowers, bolls, and leaves of plants, causing substantial damage and affecting crop yields. Effective pest management strategies, including biological control and genetically modified crops, are often employed to mitigate their impact.

some worms and caterpillars cause damage to cotton plants like the tobacco budworm and bollworm even army worms and cutworms, cotton fleahopper, aphids there are some others but they cause less damage like stinkbugs, ants, lady beetles, damsel bugs, assassin bugs even some spiders and mites
The accepted scientific name is Pectinophora gossypiella.
pesticide Bt cotton, or Bacillus thuringiensis cotton, is used the same as any other cotton. The only difference is that it has a protein genetically added which is identical to that of B. thuringiensis bacteria which is toxic to many caterpillars, especially Lepidoptera species. Therefore it is an economically important "built-in" insecticide.
Farmers typically spend significantly less on pesticides for Bt cotton compared to non-Bt varieties, primarily due to Bt cotton's inherent resistance to certain pests, particularly the cotton bollworm. On average, the reduction in pesticide costs can range from 30% to 50%, depending on regional pest pressures and farming practices. However, the exact amount spent can vary widely based on factors such as local agricultural practices, pest infestations, and market prices. Overall, the adoption of Bt cotton often leads to improved economic outcomes for farmers, including reduced pesticide expenditures.
product lifecycle management or project lifecycle management, the former is most common.
