The histopathological changes of the second instar nymph of the mealybug Phenacoccus fraxinus infected with Lecanicillium lecanii strain 3.4505 were investigated using light, scanning and transmission electron microscopy. The results demonstrated that L. lecanii 3.4505 could infect P. fraxinus in a short period. At 24 h post-inoculation, the conidia of L. lecanii 3.4505 adhered to the indented ...

Abstract Background The study was focused on identifying the pathogenic potential of native entomopathogenic fungi (EPF) viz . , Metarhizium anisopliae (Metsch.) and Lecanicillium longisporum (Zimm.) against adult tea mosquito bug (TMB), Helopeltis theivora (Waterhouse) under in vitro conditions. Results Four EPF were isolated sequence has deposited to NCBI Genbank with accession numbers MZ9303...

The occurrence of entomopathogenic fungi isolated from stored grain insect pests sampled from various geographical regions of Punjab, Pakistan, was investigated. In total, 25,720 insects from six different species were evaluated, and 195 isolates from 24 different fungal species were recovered. These included the Ascomycetes Beauveria bassiana sensu lato (Balsamo) Vuillemin (Hypocreales: Clavic...

Abstract: There are certain saprophytic fungi in the soil able to develop an antagonistic effect against eggs of parasites. Some of these fungal species are ingested by animals during grazing, and survive in their feces after passing through the digestive tract. To identify and isolate ovicidal fungi in the feces of wild captive animals, a total of 60 fecal samples were taken from different wil...

The growth of entomopathogenic fungi Lecanicillium lecanii is strongly related to the media in increasing sporulation, enhancing its effectiveness infecting target pests. This study aims obtain L. propagation with highest conidia production, and increased virulence on Cylas formicarius . first stage alternative selection consists of: Potato Dextrose Agar; maize, rice; bran. second infectivity b...

The current study was conducted to evaluate the efficiency of entomopathogenic fungus Lecanicillium lecanii (1×106) spore per gram control Dacus ciliatus on summer squash cucurbita pepo in two different stations ( Tanjaro and Tainal ) Sulaymaniyah, Kurdistan Region-Iraq, greenhouses during July November, 2021, Set up a yellow sticky trap both sides from each greenhouse determine time appearance...

Soil biochemical properties and microbial communities are usually considered as important indicators of soil health because of their association with plant nutrition. In this study, we investigated the impact of long-term application of bioorganic fertilizer (BOF) on soil biochemical properties and microbial communities in the apple orchard soil of the Loess Plateau. The experiment included thr...

Paraguay tea is a native crop of southern Brazil and is also socioeconomically important in Paraguay and Argentina. One of the main pests of this crop is Gyropsylla spegazziniana (Hemiptera: Psyllidae). As there are no registered insecticides for this pest in Brazil, the use of entomopathogenic fungi is an alternative method for its control. This study aimed to evaluate and characterize isolate...

The sweetpotato whitefly Bemisia tabaci (Gennadius) was challenged with different combinations of matrine (insecticide) and Lecanicillium muscarium (entomopathogenic fungus). Our results revealed a synergistic relationship between matrine and L. muscarium on mortality and enzyme activities of B. tabaci. To illustrate the biochemical mechanisms involved in detoxification and immune responses of ...
