Based on the importance of using low-risk compounds to protect beneficial agents, present study evaluated acute toxicity lethal and sublethal concentrations insecticides thiacloprid, pyriproxyfen, chlorantraniliprole adults Aphelinus mali (Haldeman), main parasitoid woolly apple aphid, Eriosoma lanigerum (Hausmann). Similarly, acetamiprid, buprofezin, cyantraniliprole were Acerophagus flavidulu...

This study was conducted in a commercial apple orchard (Malus domestica) with high woolly aphid (Eriosoma lanigerum) incidence, which is highly harmful to culture and infects the trunk, branch, roots, shoot, fruit. Although fungus Beauveria bassiana widely reported as control agent, there no evidence of its action against this pest. case under natural infestation conditions evaluate effective B...

Entomopathogenic fungi (EPF) are cosmopolitan soil borne pathogens that cause epizootics in various insect orders. EPF isolates of Metarhizium brunneum and M. pinghaense have shown the potential for use as biological agents important agricultural pests. The aim current study was to test persistence on apple bark over a period three weeks, under laboratory conditions. Apple sprayed with conidial...

Prociphilus fraxinifolii (woolly ash aphid) is a pest of trees (Fraxinus spp.). This species, which native to North America, was first recorded in Europe 2003, Budapest, and then began spread quickly. In 2019–2021, we detected P. Belarus (Brest) eight regions European Russia, namely Astrakhan, Nizhny Novgorod, Samara, Saratov, Smolensk, Tambov, Volgograd Voronezh regions. By 2021, has over vast...

Understanding woolly mammoth ecology is key to understanding Pleistocene community dynamics and evaluating the roles of human hunting and climate change in late Quaternary megafaunal extinctions. Previous isotopic studies of mammoths' diet and physiology have been hampered by the 'mammoth conundrum': woolly mammoths have anomalously high collagen δ(15)N values, which are more similar to coeval ...

Eriosoma lanigerum (Hausmann) (Hemiptera: Aphididae), woolly apple aphid (WAA) is an important pest on apples globally and a key of production in South Africa. The has developed some level resistance against several chemical insecticides. Entomopathogenic fungi (EPF) have been identified as promising biological control agents wide array insect pests. main aim this study was to conduct survey lo...
