Spread: This moths has a natural range across Europe, Asia, and North Africa

Characteristics: The larva is green, khaki, grey-brown or brown with dark spots. The topside is darker than the bottom side and a yellow or light brown stripe goes round the middle portion by the spots. They grow to about an inch long before pupating, As the common and scientific names suggest.

Damage: The caterpillar of this species is seen as a pest for commercial agriculture. Often referred to as the "imported cabbageworm" they are a serious pest to cabbage and other mustard family crops. It can also be a pest of cultivated brassicas and sweet peas, but it feeds on a wide range of other plants . Due to its complex life history, this species overwinters either as a larva or a brown pointed oval pupa.

Control: Organic controls for cabbage worms include handpicking, excluding them with row cover barriers, or treating with a Bt pesticide. Cabbage worms are found throughout North America, and more than one species may be found in the same garden.

Spread:The pink bollworm has spread to cotton-growing regions throughout the world.

Characteristics: The larva is green, khaki, grey-brown or brown with dark spots. The topside is darker than the bottom side and a yellow or light brown stripe goes round the middle portion by the spots.

Damage: The cotton bollworm is a moth, the larvae of which feed on a wide range of plants, including many important cultivated crops. It is a major pest in cotton and one of the most polyphagous and cosmopolitan pest species. It should not be confused with the similarly named, related species Helicoverpa zea.The cotton bollworm is a highly polyphagous species.The most important crop hosts are tomato, cotton, pigeon pea, chickpea, sorghum and cowpea. Other hosts include groundnut, okra, peas, field beans, soybeans, lucerne, Phaseolus spp., other Leguminosae, tobacco, potatoes, maize, flax, Dianthus, Rosa, Pelargonium, Chrysanthemum, a number of fruit trees, forest trees and a range of vegetable crops.

Control: Cultural controls, with the exception of the use of Bt cotton and the use of mating disruption and sprays of the Entrust formulation of spinosad are acceptable to use on organically grown cotton.

Spread:It is found in the Indo-Australian tropics. It is also established on most Polynesian islands where it occurs in a variety of island forms.

Characteristics: Adult moths measure between 15-20 mm (0.59-0.79 inches) in length and have a wingspan of 30-38 mm (1.18-1.5 inches). Forewings are gray to reddish-brown, with a complex pattern of creamy streaks and paler lines along the veins. Hind wings are grayish-white with grayish-brown margins. Males have a blue-grey band from the upper corner (apex) to the inner margin of each forewing. Larvae have bright yellow stripes along the back and the sides. Larval color varies from pale green to dark green,

Damage: Oriental Leafworm Moth Spodoptera litura is a Noctuid moth which is considered as an agricultural pest. It is also known as the Cluster caterpillar, Cotton leafworm, Tobacco cutworm, and Tropical armyworm. It has a very wide host range of over 120 plant species, including: lettuce, cabbage, beetroot, peanuts, geranium, cotton, banana, fuchsias, acacia, African oil palm, amaranth, alfalfa, strawberry, sorghum, sugarcane, tomatoes, asparagus, apple, eggplant, beet, beans, broccoli, elephants ear, horsetail she oak, corn, flax, lantana, papaya, orange, mango, leek, among many others.

Control: The use of Bacillus thuringiensis (BT) may effectively control this pest. Other forms of biological, horticultural, and cultural control that have been studied include: planting near derris and garlic plants, breeding resistant plants from wild plants for example groundnuts from wild groundnuts, breeding resistant plants using bacterium Bacillus thuringiensis genes, using a Baculovirus, using the nematode Steinernema carpocapsae, and using the fly Exorista japonica.
