Trichogramma brassicae (Bezdenko) is the most important species of Trichogramma parasitoids in Iran. The cotton bollworm, Helicoverpa armigera (Hubner) is a polyphagous insect pest that attacks many crops including cotton, maize, soybean, tomato, etc. The bollworm egg is a suitable target for many Trichogramma species. Factitious hosts such as eggs of the flour moth, Anagasta kuehniella (Zeller...

To enhance biological control of insect pests in greenhouses, facilities and procedures for mass production of the parasitoids, Eretmocerus sp., Encarsia formosa, and Trichogramma brassicae, and the predator, Aphidoletes aphidimyza were successfully developed in Hengshui, Hebei province, China. Mass production of the aphelinid wasps was achieved by using different plant varieties and host insec...

Alternaria brassicae is a necrotrophic fungus causes blight disease in oilseed mustard crop. There 47% loss of the crop due to disease. To control this disease, various chemical fungicides have been used till date which are harmful our environment. Zinc oxide (ZnO) nanoparticles synthesized from Terminalia bellerica reported significant antifungal potential against A. at 200 ppm concentration. ...

The development of indigenously isolated entomopathogenic nematodes as biological control agents was investigated. The study involved three nematode species (Heterorhabditis indica, Steinernema thermophilum and S. glaseri) and their pathogenicity against larvae of cabbage butterfly, Pieris brassicae, under laboratory conditions. Nematodes of different concentrations (0, 10, 25, 50, 75, and 100 ...

Several 2,6-bis-(un)substituted phenoxymethylpyridines were synthesized and evaluated in vitro against Fusarium graminearum, Helminthosporium sorokinianum, Alternaria brassicae, Alternaria alternata, and Fusarium oxysporum f. sp. vasinfectum. Among all derivatives, compound 3a exhibited a broad-spectrum antifungal activity against the five phytopathogenic fungi.

Received: October 27, 2016 Revised: December 23, 2016 Accepted: January 04, 2017 Abstract: Aims: Lettuce and broccoli are high value vegetable crops in California. The western flower thrips, Frankliniella occidentalis on lettuce, and the cabbage aphid, Brevicoryne brassicae and the green peach aphid, Myzus persicae on broccoli are important insect pests that are frequently managed with chemical...

Camalexin has been reported to play defensive functions against several pathogens in Arabidopsis. In this study, we investigated the possible role of camalexin accumulation in two Arabidopsis genotypes with different levels of basal resistance to the compatible eH strain of the clubroot agent Plasmodiophora brassicae. Camalexin biosynthesis was induced in infected roots of both Col-0 (susceptib...
