Early blight can be caused by two different closely related fungi, Alternaria tomatophila and Alternaria solani.Alternaria tomatophila is more virulent on tomato than A. solani, so in regions where A. tomatophila is found, it is the primary cause of early blight on tomato. However, if A. tomatophila is absent, A. solani will cause early blight on. Pest breeds throughout the year. Moths are active at night. Adults live for 7-10 days. Total life cycle takes 32-60 days.

stored grain pests In India, post-harvest losses caused by unscientific storage, insects, rodents, micro-organisms etc., account for about 10 per cent of total food grains.

Pickleworms (on most cucurbits) and squash vine borers (on squash) can cause serious damage to field-grown cucurbits. In the greenhouse, cucumbers are likely to be infested with aphids, spider mites, leafminers, and cucumber beetles, which are common outdoors and in greenhouses, are vectors of the bacterial wilt organism. The most common pest species­—such as greenhouse whitefly (Trialeurodes vaporariorum) and sweetpotato whitefly (Bemisia tabaci)—have a wide host range that includes many weeds and crops. These species breed all year round in warmer parts of California, moving from one host to another as plants are harvested or dry up Pests. Scale insect (Saissetia nigra Nietn.)

In this section, different ways in which insect pests are harmful to us are classified. 1. Destroying crops and valuable plants Early blight: biology. Early blight is an endemic disease - it exists in virtually every potato field in Canada and can lead to yield losses if not treated. First, infected leaf tissue reduces the crop's photosynthetic capacity which on its own reduces yield, but then it also erodes the crop's ability to bulk up its tubers leading to.

Thrips, order Thysanoptera, are tiny, slender insects with fringed wings. They feed by puncturing the epidermal (outer) layer of host tissue and sucking out the cell contents, which results in stippling, discolored flecking, or silvering of the leaf surface. Thrips feeding is usually accompanied by black varnishlike flecks of frass (excrement) Late blight, also called potato blight, disease of potato and tomato plants that is caused by the water mold Phytophthora infestans. The disease occurs in humid regions with temperatures ranging between 4 and 29 °C (40 and 80 °F). Hot dry weather checks its spread. Potato or tomato plants that are infected may rot within two weeks Farmers lose an estimated average of 37% of their rice crop to pests and diseases every year.

The squash beetle feeds upon the leaves of cucurbits. The other species, the Mexican bean beetle (Epilachna varivestis), a close relative of the squash beetle, is a serious bean pest. The adult of the squash beetle overwinters in crop debris. All other lady beetles are beneficial because they feed on insect pests, such as aphids and scale insects Propagation Yams are propagated vegetatively from small tubers. Land should be prepared for planting by plowing and harrowing. Tubers should be planted in trenches to a depth of 15 cm (6 in) allowing at least 30 cm (12 in) between individual plants and 1.5 m (5 ft) between rows.
