Purification and characterization of myrosinase from the cabbage aphid (Brevicoryne brassicae), a brassica herbivore.
Aphids are among the most serious insect pests of agricultural crops in the world. They often have specific hosts, and the cabbage aphid (Brevicoryne brassicae) is a specialist on Cruciferae. It has previously been described that certain insects contain the enzyme myrosinase (EC 3.2.3.1), which is considered an important defence enzyme of crucifers. Myrosinase was purified to homogeneity from c...
متن کاملPurification and characterisation of a non-plant myrosinase from the cabbage aphid Brevicoryne brassicae (L.).
Plant myrosinases and glucosinolates constitute a defence system in cruciferous plants towards pests and diseases. We have purified for the first time a non-plant myrosinase from the cabbage aphid Brevicoryne brassicae (L.) to homogeneity. The protein was N-terminally blocked and protease (trypsin and lys c) degradation gave peptides of which five were sequenced. The protein is a dimer with sub...
متن کاملEvaluation of Entomopathogenic Fungi Against Chilli Thrips, Scirtothrips dorsalis
Commercial strains of entomopathogenic fungi were evaluated for control of chilli thrips, Scirtothrips dorsalis Hood (Thysanoptera: Thripidae), an invasive pest of ornamental and vegetable plants in the Caribbean and southeastern United States. In laboratory assays, LC50 values against adult S. dorsalis were 5.1 × 10(4) CFU/mL for Beauveria bassiana GHA, with higher values 3.1 × 10(5) for Metar...
متن کاملEntomopathogenic Fungi Screening against Fruit Fly in Thailand
The screening of entomopathogenic fungi, 7 isolates of Metarhizium spp., 12 isolates of Beauveria spp., and 1 isolate of Hirsutella citriformis against fruit fly was performed in Lampang Agricultural Research and Training Centre, Lampang, Thailand. The efficacy test was done by spraying suspension of 10 spores per ml of fungus on Bactrocera dorsalis in completely randomized design experiments. ...
متن کاملFactors Affecting Abundance and Damage Caused by Cabbage Aphid, Brevicoryne brassicae on Four Brassica Leafy Vegetables: Brassica oleracea var. Acephala, B. chinense, B. napus and B. carinata
Resistance of four brassica leafy vegetables: kale, Chinese cabbage, rape and Ethiopian mustard to cabbage aphid, Brevicoryne brassicae (L.) was studied in cage experiments at the Botswana College of Agriculture, Gaborone, Botswana. A completely randomised design with cultivars as treatments and four replicates per treatment was used. One newly laid nymph was placed on each of the four potted p...
