results significant differences were observed in the results of co-culture of nematodes larva and fungi after seven days. the most effective fungi against the nematodes larvae were cladosporium sp., trichoderma sp., fusarium equisetti, after seven days of incubation. materials and methods sheep feces were employed to provide the required third stage larvae source for the experiments. the nemato...

background the brown-banded cockroach supella longipalpa (f.) as a mechanical vector of pathogens and source of allergens has recently become widespread in the city of ahvaz, southwestern iran. objectives this research was done to evaluate the efficacy of a dust-formulation of metarhizium anisopliae isolate iran 437c, as a common entomopathogenous fungus, against s. longipalpa. materials and me...

cardaria draba is an important, troublesome weed in the sustainable production of wheat. inthe first step of this study, 100 actinomycete isolates were purified from soil samples collectedfrom the rhizosphere and phyllosphere of plants in different provinces of iran. all isolates weresubjected to primary screening by assaying the fermentation broth of the sterile surfaces of c.draba leaves. con...

parasitoids of the genus, trichogramma are the most widely used natural enemies for biological control of pests worldwide. the presence of flowering plants can improve efficiency of biological control agents by supplying sugar resource for parasitoids. in this study, two experiments were performed under laboratory condition (at 25±1ºc, 60±10% rh and a photoperiod 16l:8d), to evaluate the effect...

a suitable diet and oviposition substrate are two basic needs for successful mass rearing of orius spp. and this may reduce their production costs. the effect of various foods containing eggs of ephestia kuehniella and sitotroga cerealella with various pollens were investigated on the biological parameters of o. albidipennis in the laboratory. moreover, survival, hatching rate and fecundity of ...

background: chemical control method using different acaricides as spray, dipping solution or pour-on is routinely used for controlling ticks. biological control agents are favorable due to their safety for animals and environment. entomopathogenic fungi such as beauveria bassiana are well known for controlling ticks. in this study, two iranian indigenous strains of b. bassiana ( b. bassiana 519...

nasonovia ribisnigri (mosely) is one of the most important pests of the lettuce plant and it was reported for the first time in ahvaz in 2008. in order to investigate the dominant species of its natural enemies and their population fluctuations, sample were taken arbitrarily from fifty plants twice a week during the growing season in 2010-2012. in this study, ten species of predators, three spe...

fusarium solani wasisolated from diseased roots of common bean (phaseolus vulgaris) grown in fields which were severely infected with fusarium root rot of bean in markazi province of iran. specific pcr primer pairs were used for the identification and verification of f. solani (mart.) f.sp. phaseoli (burkholder) w.c. snyder and n.h. hans. spore suspensions of f. solani f.sp. phaseoli were subje...

effects of induced mutation via gamma irradiated with 250 gy dose (in nuclear agriculture research school- nuclear science and technology research institute) on trichoderma harzianum conidiaon chitinase activity by sts molecular marker have been evaluated in this study. among 20 irradiated mutants which selected via improved antagonistic capability against rhizoctonia solani, pcr amplified chit...

among fungi, species of the genus paecilomyces are considered as promising biological control agents with high potential to reduce root-knot nematode (rkn) and other nematode populations. in this research we investigated a soil hyphomycetes, paecilomyces marquandii and its pathogenicity on eggs of rkn in vitro. in greenhouse test, root weight, plant length, fresh weight and dry weight of plants...
