VARIOUS CROPS IMPROVEMENT OF BIOPESTICIDES AGAINST COMMON PESTS

Bacillus thuringiensis – Based Biopesticides Against Agricultural Pests in Latin America

Utilization of biopesticides as sustainable solutions for management of pests in legume crops: achievements and prospects

Grain legumes remain important to meet the projected targets relating to food and nutritional security worldwide. The complementation of cereal-based food with grain legumes is a vegetarian diet with high-quality protein. However, the performance of these crops is severely influenced by a number of biotic and abiotic stresses, of which pests and pathogens remain the crucial affecting plants at ...

Comparative virulence of Beauveria bassiana isolates against lepidopteran pests of vegetable crops.

Forty-three isolates of the entomopathogenic fungus Beauveria bassiana were screened for virulence against second-instar larvae of diamondback moth (Plutella xylostella) (DBM), European corn borer (Ostrinia nubilalis) (ECB), corn earworm (Helicoverpa zea) (CEW), and fall armyworm (Spodoptera frugiperda) (FAW); 30 of these isolates were tested against beet armyworm (Spodoptera exigua) (BAW). Hig...

Air War Against Pests

T. HE AIRPLANE holds a bright new hope in the farmers' uphill struggle with insects. Since 1922, when Department engineers and entomologists developed a practical method for dusting cottonfields with calcium arscnatc to protect the crop against the boll weevil, commercial airplane dusting has become routine, particularly in cultivated fields that spread over a wide area unbroken by trees or shr...

Cover crops and control of arthropod pests of agriculture

Cover crops can harbor both harmful and beneficial arthropods (1, 3). Damage to cover crops themselves is rarely of concern; more important is the possibility that pests harbored amid cover crops may disperse to adjoining cash crops [see Kennedy and Margolies (31) for a discussion of the dynamics of such mobile pests]. Here, I explore the roles that cover crops play in the life cycles and popul...
