The boll weevil (Anthonomus grandis) is a species of beetle in the family Curculionidae.The boll weevil feeds on cotton buds and flowers. Thought to be native to Central Mexico, [1] it migrated into the United States from Mexico in the late 19th century and had infested all U.S. cotton-growing areas by the 1920s, devastating the industry and the people working in the American South.
Dysdercus cingulatus is a species of true bug in the family Pyrrhocoridae, commonly known as the red cotton stainer. [1] It is a serious pest of cotton crops, the adults and older nymphs feeding on the emerging bolls and the cotton seeds as they mature, transmitting cotton-staining fungi as they do so.
Many weevils are considered pests because of their ability to damage and kill crops. The grain or wheat weevil (Sitophilus granarius) damages stored grain, as does the maize weevil (Sitophilus zeamais), among others. The boll weevil (Anthonomus grandis) attacks cotton crops; it lays its eggs inside cotton bolls and the larvae eat their way out ...
Oxycarenus laetus is a polyphagous insect, feeding on the seeds of a number of plants in the Malvaceae family. As well as being a pest of cotton (Gossypium spp.) crops, this insect is found on Abutilon indicum (Indian mallow), Sida acuta (common wireweed) and Thespesia populnea (portia tree). On these plants, populations are at their highest ...
They chew through the cotton lint to feed on the seeds. Since cotton is used for both fiber and seed oil, the damage is twofold. Their disruption of the protective tissue around the boll is a portal of entry for other insects and fungi. The pink bollworm is native to Asia, but has become an invasive species in most of the world's cotton-growing ...
Many species of owlet moths are considered an agricultural problem around the world. Their larvae are typically known as "cutworms" or "armyworms" due to enormous swarms that destroy crops, orchards and gardens every year. The Old World bollworm (Helicoverpa armigera) produces losses in agriculture every year that exceed US$2 billion. [30]
The three main crops that Adelphocoris lineolatus show the most attraction for are flowering alfalfa, cotton, and mung bean crops. [13] Biologists have observed a relationship between three chemosensory proteins found in the antennae of A. lineolatus and the semiochemicals released by flowering alfalfa, cotton, and mung bean crops resulting in ...
Spodoptera litura, otherwise known as the tobacco cutworm or cotton leafworm, is a nocturnal moth in the family Noctuidae. S. litura is a serious polyphagous pest in Asia, Oceania, and the Indian subcontinent that was first described by Johan Christian Fabricius in 1775. [1] Its common names reference two of the most frequent host plants of the ...
