THE MAIN SUCKING INSECT PESTS AND THEIR ASSOCIATED PREDATORS ON OKRA PLANTS

Insect Pests and Arthropod Predators Associated with Tree-Turf Landscapes

Persistence of new insecticides and their efficacy against insect pests of okra.

Persistence and efficacy of bifenthrin (25 and 50 g ai ha(-1)), fipronil (50 and 100 g ai ha(-1)) and indoxacarb (70 and 140 g ai ha(-1)) has been studied in okra fruits. The initial deposits varied from 0.259-0.382 microg g(-1) at low and 0.461-0.688 microg g(-1) at high rate of application. The residues persisted upto 10 days with half-life of 1.32-1.58 days for bifenthrin, 0.65-1.12 days for...

Novel Genes for Control and Deterrence of Sucking Insect Pests

Current GM crops are thus far the almost exclusive domain of herbicide and insect resistance traits. The Bt toxins used for insect control have a narrow specificity against lepidopteran and coleopteran pests only. Yet, aphids and thrips are highly important pests worldwide, causing severe direct losses and transmitting devastating viruses such as Tomato Spotted Wilt Virus (TSWV). So far, few us...

Insect pests of tea and their management.

Globally, 1031 species of arthropods are associated with the intensively managed tea Camellia sinensis (L.) O. Kuntze monoculture. All parts of the plant, leaf, stem, root, flower, and seed, are fed upon by at least one pest species, resulting in an 11%-55% loss in yield if left unchecked. There has been heavy use of organosynthetic pesticides since the 1950s to defend the plant against these p...

Survey Studies on Insect-pests Associated with Important Medicinal Plants in Himachal Pradesh

Indian Himalayan region is one of the richest sources of biodiversity in the world, having a wide range of medicinal and aromatic plants. The present studies were undertaken to record the insect-pest complex of some important medicinal plants. In all fifteen insect species belonging to four orders were observed to be associated with ten medicinal plants in different parts of Himachal Pradesh. A...
