Diamondback moth: Feeding preference among commercial varieties of head cabbage
Thirty-nine commercial varieties of head cabbage were evaluated for feeding preference of the diamondback moth (DBM), Plutella xylostella, at Kula, Hawaii, USA. 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 کاملFitness of Bt‐resistant cabbage loopers on Bt cotton plants
Development of resistance to the insecticidal toxins from Bacillus thuringiensis (Bt) in insects is the major threat to the continued success of transgenic Bt crops in agriculture. The fitness of Bt-resistant insects on Bt and non-Bt plants is a key parameter that determines the development of Bt resistance in insect populations. In this study, a comprehensive analysis of the fitness of Bt-resi...
متن کاملEffect of parasitoid elimination on populations of diamondback moth in cabbage
An insecticidal exclusion method was used to assess the effect of parasitoids on level of infestation by the diamondback moth (DBM), Plutella xylostella (L.) (Lepidoptera: Plutellidae), 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 کاملGlucosinolate Profiles in Cabbage Genotypes Influence the Preferential Feeding of Diamondback Moth (Plutella xylostella)
Diamondback moth (DBM), Plutella xylostella L., is a devastating pest of cabbage worldwide whose feeding attributes are influenced by glucosinolate profiles of the plant. Identifying the specific glucosinolates associated with plants' resistance mechanism can provide cues to novel points of intervention in developing resistant cultivars. We studied the DBM larval feeding preference and extent o...
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...
