Matsucoccus matsumurae (Kuwana) (Hemiptera: Coccoidea: Matsucoccidae) is an invasive alien species and a destructive pest of two native Chinese pines, Pinus tabulaeformis Carr. and P. massoniana Lamb., throughout the eastern regions of China. The pathogenicity of three entomopathogenic fungi, Lecanicillium lecanii strain V3.4504 and V3.4505, Fusarium incarnatum-equiseti strain HEB01 and Lecanic...
The fungus Lecanicillium is belonging to the order Hypocreales and is described as anamorphic Cordycipitaceae. This genus is known by its ability to infect other species of fungi such as Agaricus spp., Sphaerotheca spp. [1], Puccinia spp. [2]...etc. On the other hand, it was recorded as entomopathogenic fungus as it can parasitize some species of insects like Mosquito larvae [3]&[4] Bombyx mori...
The entomogenous fungus, Lecanicillium lecanii is hyperparasitic on Hemileia vastatrix , the cause of coffee leaf rust in the laboratory, and has frequently been observed attacking it in the field. The existence of a complex ecological web involving the spatially clustered mutualism of an ant ( Azteca instabilis ) with a scale insect ( Coccus viridis ), where the scale insect was infected by L....
To supply essential information for improving mass production and biocontrol effi cacy, two-stage cultivation on agar plates was used to evaluate the environmental conditions affecting mycelial growth and sporulation of seven biocontrol fungi. Maximum growth and sporulation occurred on acid media for Paecilomyces (Pa.) lilacinus IPC-P, Pochonia (Po.) chlamydosporia HSY-12-14, and Lecanicillium ...

The entomopathogenic fungus Lecanicillium lecanii persists in a highly dynamic network of habitat patches (i.e., a metapopulation) formed by its primary host, the green coffee scale Coccus viridis. Lecanicillium lecanii is an important biological control of both C. viridis and the coffee rust, Hemileia vastatrix. Successfully managing this biocontrol agent will depend on an increased understand...
Recent studies have shown that the spatial pattern of nests of an arboreal ant, Azteca instabilis (Hymenoptera: Formicidae), in a tropical coffee agroecosystem may emerge through self-organization. The proposed self-organization process involves both local expansion and density-dependent mortality of the ant colonies. We explored a possible mechanism for the density-dependent mortality involvin...
اثرات قارچ بیمارگر lecanicillium lecanii و عصاره ی میوه citrullus colocynthis روی ملخ chrotogonus trachypterus (orth: pyrgomorphidae) چکیده در این بررسی، تاثیر کشندگی قارچ lecanicillium lecanii (zimm.) viegas و عصاره ی میوه citrullus colocynthis (linn.) schrad روی ملخ chrotogonus trachypterus (orth: pyrgomorphidae) در شرایط آزمایشگاهی (دمای 2±24 درجه سانتیگراد، رطوبت نسبی 5±40، و دوره ی نور...
در این تحقیق، تاثیر دو حشره کش شیمیایی و دو قارچ بیمارگر روی حشرات کامل شته ی رز، macrosiphum rosae linnaeus در شرایط آزمایشگاهی(1± 25 درجه ی سیلسیوس، رطوبت نسبی5 ± 80 درصد برای قارچ ها و رطوبت نسبی 5±60 درصد برای حشره کش ها، دوره ی نوری 12ساعت تاریکی و 12 ساعت روشنایی) مطالعه شد. برای زیست سنجی حشره کش ها، برگ های رز به مدت 10 ثانیه در هر غلظت غوطه ور شدند و اجازه داده شد به مدت 15 دقیقه خشک ش...
The entomopathogenic fungi Beauveria bassiana, Metarhizium anisopliae, Lecanicillium lecanii and Isaria fumosorosea were tested for their efficacy in managing the exotic spiraling whitefly Aleurodicus dispersus (Hemiptera, Aleyrodidae) on cassava (Manihot esculenta) during 2 seasons (2011-2012 and 2012-2013). The fungi I. fumosorosea and L. lecanii exhibited promising levels of control (> 70% m...
