Cotton red fang moth - Pectinophora gossypiella

Japanese: ワタアカキバガ(綿赤牙蛾) - ワタアカキバガ（英語表記）Pectinophora gossypiella

An insect of the Lepidoptera family Gelechiidae. Wingspan is about 1.5cm. The wings are long and slender, with the outer edge of the forewings inclined and the tip of the hindwings slightly pointed. The forewings are reddish brown with irregular dark markings. It is believed to have originated in India, but has spread to cotton-growing areas around the world and become a major pest. The larvae, also known as pink cotton bugs, cause great damage by feeding on the seeds in cotton buds, flowers, and capsules. Under good conditions, one generation is completed in one month, but under adverse conditions such as low temperature, dryness, and lack of food, the larvae go into hibernation.

鱗翅目キバガ科の昆虫。翅の開張1.5cm内外。翅は細長く，前翅外縁は傾斜しており，後翅頂はややとがりぎみ。前翅は赤みをおびた褐色で，不規則な暗色紋がある。原産地はインドと推定されるが，世界中のワタ作地に広がり，最悪の害虫となってしまった。幼虫はワタアカミムシとも呼ばれ，ワタのつぼみ，花，蒴果（さくか）内の種子を食べるため，被害がきわめて大きい。条件がよければ1ヵ月で1世代を完了するが，低温，乾燥，食餌欠乏などの悪条件下では幼虫は休眠する。
