Varieties were evaluated for density of caterpillars, extent of feeding damage and percentage of marketable heads. Twelve out of 39 (31%) varieties that showed the least DBM caterpillar damage and produced high percentage of marketable ...
متن کاملEffect of Plant Age on Survival of Diamondback Moth on Two Cabbage Genotypes
Table 1. Percentage of larvae surviving on cabbage cultivar Round Up and diamondback moth-resistant glossy-leafed cabbage NY 2518, and relative resistance of NY 2518 (survival on NY 2518 expressed as a percentage of that on ‘Round Up’) at five plant ages and two inoculation schemes. Knowledge of age-dependent expression of resistance is critical for evaluation of breeding lines and for effectiv...
متن کاملEffect of parasitoid elimination on populations of diamondback moth in cabbage

In field trials conducted at Rietondale, Pretoria, Gauteng Province and Brits, North-West Province, South Africa, a selective organophosphate pesticide, with systemic and contact action, dimethoate, ...
متن کاملThe Control of Diamondback Moth with Thuricide
Thuricide, a Bacillus thuringiensis formulation, is active against more than 200 lepidopterous species in their larval stage. Best efficacy is obtained when Thuricide is applied at hatching time and/or on 1st to 3rd larval instars during their intensive feeding period. Since Thuricide must be eaten by the insect to be effective, thorough leaf coverage is essential for best results. Thuricide HP...
متن کامل16 Biological Control of Diamondback Moth

In some countries, however, it is effectively suppressed by parasites. These are critically examined as are the various attempts to import parasites and to release them. The appraisal reveals that the parasites of P. xylostella are a valuable control component an...
