The pink bollworm (Pectinophora gossypiella; Spanish: lagarta rosada) is an insect known for being a pest in cotton farming. The adult is a small, thin, gray moth with fringed wings. The larva is a dull white caterpillar with eight pairs of legs [1] with conspicuous pink banding along its dorsum. The larva reaches one half inch in length.
Pectinophora is a genus of moths in the family Gelechiidae.Perhaps the best known species is the pink bollworm, Pectinophora gossypiella (Saunders). P. gossypiella is one of the world's most destructive insect pests that causes terrible damage to cotton bolls.
Pectinophora scutigera, the Queensland pink bollworm or pinkspotted bollworm, is a moth of the family Gelechiidae. It was described by Holdaway in 1926 from Australia, where it occurs in coastal and central Queensland. It has also been recorded from Hawaii, New Guinea, Micronesia and New Caledonia. [1]
It is known as the cotton bollworm, corn earworm, Old World (African) bollworm, or scarce bordered straw (the lattermost in the UK, where it is a migrant). [ 2 ] [ 1 ] The larvae feed on a wide range of plants, including many important cultivated crops.
Groundcover: Delosperma (Delosperma), also known as ice plant, is a low-growing succulent with flowers that appear from spring to fall in brilliant neon colors, including hot pink, orange, and purple.
Since it is polyphagous (feeds on many different plants) during the larval stage, the species has been given many different common names, including the cotton bollworm and the tomato fruitworm. It also consumes a wide variety of other crops. [2] The species is widely distributed across the Americas with the exception of northern Canada and Alaska.
The hypothesis was that sterile males mating with the few surviving females, who had developed resistance, would lead to a decrease in pests in the following generation. There was a dramatic reduction in pink bollworms, with only two pink bollworm larvae being found by the third year of the study. [17]
