Caterpillars of the second - third instars hibernate; their emergence from diapause occurs in early April. The timing and duration of development of each of the three generations of the boxwood firefighter in the conditions of the Crimea were determined, the lifespan of the imago was determined, averaging about two weeks, with some individuals living for more than 20 days. The sex index in adults varies in different generations, depending on the living conditions. Thus, in the central foothill region in the first generation, the ratio of females and males reaches 2: 1, and in the second generation, both the proportion of males and melanistic individuals increases in comparison with typically colored butterflies. In each of the three generations, males emerged from pupae 3-5 days earlier than females. The fertility of melanistic females is higher than that of the typically colored. A spring-summer diapause was observed in caterpillars of II-III instars in the overwintered, first and second generations.","PeriodicalId":20414,"journal":{"name":"PLANT PROTECTION NEWS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81815026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under arid conditions of 2019, the high level of potato tubers damage by wireworms has been recorded in July only. Over dry seasons a short-time contacts of wireworm larvae with food and water sources in the dry soil and their migrations to the deeper and more humid levels are most possible. Under such conditions, the larvae could not be observed during the attractive baits changing or the dig-upping of potato samples, despite the damaged tubers presence. Thus, in case of dry spring the evaluation of the wireworm population density before the potato planting using the standard method of “sample plots” could give the biased results. In this case, it is necessary to undertake the entire complex of preventive measures independently from the results of pest number evaluations over the spring season. It has been shown that the larvae of A. lineatus developed the food preferences for the tubers of different potato varieties during entire vegetative period starting from the potato planting. As a result of the numerous field evaluations over 2015-2019 the resistant varieties Alyi Parus, Liga, Nayada, Sirenevyi Tuman has been distinguished. Preliminary data of the 2019 have shown that the varieties Red Fantasy, Gala, Gusar, Manifest, Rubin and others are also resistant to wireworms.","PeriodicalId":20414,"journal":{"name":"PLANT PROTECTION NEWS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83614054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two other strains of species L. psalliotae and A. muscarius did not affect the behavioral responses and fecundity of whitefly. All studied strains showed high virulence against whitefly larvae at concentration of 5 mln spores/ml causing mortalily rate between 76 and 98 % on the 7th day after treatment. The virulence of species L. dimorphum and L. pissodis was comparable with the virulence of the species A. muscarius, they are traditionally used to produce biopreparations against whitefly.

The basis for the maps was the online resource “Interactive Agricultural Ecological Atlas of Russia and Neighboring Countries. Economic Plants and their Diseases, Pests and Weeds” published twelve years ago. New data on the distribution of these species as well as recent publications were used in the verification of the distribution of these species in Russia. Corrections and additions were made based on the analysis of published information about the species’ distribution in certain areas and regions, therefore new maps are more reliable and detailed. The data for each region were used to merge areas of occurrence rates designated as “very frequent”, “frequent” and “common” into one “frequent” occurrence zone. Similarly, areas of occurrence rates of “rare”, “very rare”, “infrequent” and “sporadic” were merged into one “infrequent” occurrence zone. Area with “frequent” occurrence rate is identified as the zone of harmfulness. It was shown, that for Siberian lettuce there is no harmfulness zone since this species has habitats in coasts and forest margins and rarely occurs in ruderal and segetal habitats. Its distribution can be classified into zones of “frequent” and “infrequent” abundance.","PeriodicalId":20414,"journal":{"name":"PLANT PROTECTION NEWS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81900129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The systems of digestive hydrolases of phytophagous insects have been established during their long-term co-evolution with plants. This is also true for herbivorous bugs, including a dangerous pest of wheat, the Sunn bug (also known as the Sunn pest). Proteases are the main economically significant damage factor of representatives of the genus Eurygaster and other bugs harmful to the wheat grain. Proteases disrupt the structure of gluten and seriously impair the baking qualities of flour. α-Amylases provide assimilation of starch, the main source of energy for these insects. The data on digestive α-amylases and proteases of the Sunn pest remain fragmentary. Little is known regarding the enzymes involved in bugs’ feeding by the vegetative parts of cereals. There are many ways to strengthen gluten damaged by bugs, though not all of them are safe. Proteinaceous inhibitors of proteases and other hydrolases are considered as promising elements to develop safe for health and ecofriendly means to control wheat bugs and reduce their damage to the grain quality. The reduced sensitivity of the Sunn pest proteases to protein inhibitors can be overcome by constructing novel inhibitors based on their known forms, as well as by involving other highly specific approaches, including the use of antibodies to active enzyme centers or RNA interference. The bugs’ proteases themselves can be used in the diagnosis of grain damage, in food technologies and in medicine.","PeriodicalId":20414,"journal":{"name":"PLANT PROTECTION NEWS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87283623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To identify the resistance genes ( Sr2, Sr24, Sr25, Sr26 , Sr28, Sr31, Sr32, Sr35, Sr36, Sr38, Sr57 , and Sr1A1R ), specific primers were used. Among the bread wheat varieties analyzed, those with high resistance to stem rust and known resistance genes were identified: Astarta ( Sr31 ), Vekha ( Sr31 ), Obskaya Ozimaya ( Sr31 ), Leonida ( Sr31 ), Karavan ( Sr31 ), Alekseich ( Sr31 ), Step’ ( Sr31 ), Bezostaya 100 ( Sr31+Sr57 ), Zhiva ( Sr31+Sr57 ) Vanya ( Sr31+Sr57 ) and Velena ( Sr31+Sr28 ). The latter four varieties possessed combinations of the Sr31 gene, effective against Russian populations of P. graminis f. sp. tritici , and Sr28 and Sr57 genes, effective against the Ug99 race group.
