Effects of four host plants, tobacco, Chinese cabbage, cowpea and sweet potato, on larval and pupal development and survival, and longevity and fecundity of adults of Spodoptera litura (F) (Lepidoptera: Noctuidae), were studied under laboratory conditions (26 degrees C, 60-80% RH), as was the utilization of the four host plants and adaptation on tobacco. All of the biological parameters include...

J. Econ. Entomo!. 75: 492-494·(1982) Studies conducted to determine Thrips tabaci Lindeman damage and contamination in sauerkraut revealed that both occur at detectable levelsin processedcabbage, althoughsuch levelsare much lower than predicted from examination of fresh cabbage. Addition of the chemical preservativessodium benzoate (0.1%) and potassiummetabisulfite (0.05%) had no effect on plan...

Utilization of a novel plant host by herbivorous insects requires coordination of numerous physiological and behavioral adaptations in both larvae and adults. The recent host range expansion of the crucifer-specialist diamondback moth (DBM), Plutella xylostella L. (Lepidoptera: Plutellidae), to the sugar pea crop in Kenya provides an opportunity to study this process in action. Previous studies...

The present study was carried out to investigate the microbiological quality and incidence of pathogenic bacteria found in green chilli and cabbage from different shops in Dhaka city. A total of 20 samples, 10 green chillies (Capsicum annuum) and 10 cabbages (Brassica oleracea var. capitata) were randomly collected from 20 sampling sites in central Dhaka. The numbers of total heterotrophic bact...

The mutualistic symbiont Piriformospora indica exhibits a great potential in agriculture. The interaction between P. indica and Chinese cabbage (Brassica campestris cv. Chinensis) results in growth and biomass promotion of the host plant and in particular in root hair development. The resulting highly bushy root phenotype of colonized Chinese cabbage seedlings differs substantially from reports...

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...

This study was conducted to evaluate the effect of pulsed electric field (PEF) treatment on anthocyanin extraction from red cabbage using water as a solvent. Mashed cabbage was placed in a batch treatment chamber and subjected to PEF (2.5 kV/cm electric field strength; 15 micros pulse width and 50 pulses, specific energy 15.63 J/g). Extracted anthocyanin concentrations (16 to 889 microg/mL) wer...

Genistein (GNT), an isoflavone, is used in the clinical treatment of various health disorders. GNT is found in primary food source plants and some medical plants. However, studies on the functions of GNT in plants are rarely reported. In this study, we demonstrated that GNT plays an important role in promoting anthocyanin accumulation in red cabbage. GNT solutions (10, 20, 30, 40, and 50 mg/L) ...

Following the 2011 Fukushima Daiichi Nuclear Power Plant accident, the preservation of the food chain from radionuclides contamination has become of crucial importance. The potential of Dark septate endophytic fungi in the management of Cs accumulation in plants under contaminated environments was investigated using Chinese cabbage and tomato plants. Four endophytic fungal isolates of different...

Use of non-glossy collards as a trap crop for control of the diamondback moth, Plutella xylostella (L.), in commercial fields of cabbage in New York was unsuccessful because it neither reduced the number of larvae on cabbage nor concentrated the insects on collards. In laboratory and outdoor screenhouse experiments, P. xylostella preferentially laid its eggs on the glossy-type Barbarea vulgaris...
