The Chinese species Cryptococcus ulmi Tang & Hao is found to be distantly related to other sampled Cryptococcus species based on both molecular and morphological study. A new felt scale genus, Macroporicoccus Nan & Wu gen. n., is erected therefore for C. ulmi. The new genus differs from other eriococcid genera due to the presence of large simple pores, here referred to as macrodisc pores. The a...

The systematic and long-term use of pesticides in fruit plantations leads to the formation resistant pest populations. purpose this work was evaluate effectiveness entomophages acariphages for protection apple orchards. Against dominant Cydia pomonella (Linnaeus), Habrobracon hebetor (Say) used, which caught Krasnodar Territory using cassettes with caterpillars attractive H. hebetor. To determi...

AIMS   For Ophiostoma (Ceratocystis) ulmi, the ability to undergo morphological change is a crucial factor for its virulence. To gain an understanding of quorum-sensing activity in O. ulmi as it relates to yeast-mycelium dimorphism control, this study examines the effects of branched-chain amino acids as well as their fusel alcohols and fusel acids as quorum sensing molecules. METHODS AND RES...

The first checklist of spider mites (Tetranychidae) Transcarpathia, Ukraine is compiled based on the revision collection materials stored in I.

Putrashik, and authors were studied, thus covering a 45 year-long period research study region. includes 28 species 10 genera tetranychid mites, which about 40...

The effects of three sulfur products (calcium polysulfide [= lime sulfur], dry flowable sulfur, and ammonium thiosulfate, a plant nutrient), were tested in bioassays against a predatory mite, Galandromus occidentalis (Nesbitt), and two species of tetranychid (pest) mites, twospotted spider mite (Tetranychus urticae Koch) and European red mite [Panonychus ulmi (Koch)]. Calcium polysulfide and am...
