Libyostrongylus douglassii is a gastrointestinal nematode parasite of ostriches that can cause up to 50% mortality in young birds. The objective of this study was to compare the predatory capacity of two isolates of the predatory fungi Duddingtonia flagrans (AC001 and CG722 isolates) and one of Arthrobotrys cladodes (CG719) on infective larvae (L3) of L. douglassii under laboratory conditions, ...

The larvicidal effect of secondary metabolites Verticillum lecanii,Pencillium chrysogenum and Aspergillus niger against filaria vector Cx.quinquefasciatus was investigated. efficacies have been tested at four different concentrations mentioned fungi (25,50,75,100)ppm .larvicidal efficacy demonstrates that larval mortality related to concentration, exposure time age. Higher observed high moreove...

This study determined the efficacy of Beauveria bassiana (Balsamo-Crivelli) Vuillemin (Hypocreales: Cordycipitaceae) alone or combined with diatomaceous earth DEA (a mixture DE + abamectin) against adults and larvae Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). was evaluated at 50 ppm while fungi 1.6 × 105, 106, 107 conidia/kg wheat). Mortalities were assessed after 7 14 days exposu...

Abstract Background The fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is an important pest of tomatoes that reduces yield and fruit quality resulting in losses up to 100%. has developed resistance chemical insecticides, therefore necessitating alternative control measures. entomopathogenic fungi (EPF) Beauveria bassiana Metarhizium anisopliae have been exploited e...

Parasitic helminths eggs released into the environment through defecation of definitive hosts are affected by various environmental factors [1]. It is believed that these eggs are also invaded and eliminated by different biological agents including fungi [2]. Nematophagous fungi are potential agents for biocontrol of helminths eggs; these fungi, divided into predators, endoparasites, and ovicid...

Examining dead insects from different locations in Mazandaran, Gilan and TehranProvinces, specimens with fungal outgrowth were selected for further investigations. After isolation and purification of fungi they were identified as follows:Beauveria brongniartii (Sacc.) Petch*On Coccinella septempunctata, Tehran Prov., Varamin, Ghara-Aghaj mountains, M.H. Ghassemi (IRAN 1025 C). Paecilomyces tenu...
