Insects have a variety of defense mechanisms against infectious diseases, namely phenoloxidase, hemocytes, detoxification and antioxidant enzymes.The instinctive immune system of insects is highly advanced and depends on humoral and cellular elements. In this study, five haemocytes types were found in fifth nymphal instar and adults of green bug, Nezara viridula (Heteroptera: Pentatomidae) namely; prohaemocyte (pr),granulocyte (gr), spherulocyte (sp), plasmatocyte (pl), coagulate cells (co) and oenocytoid (oe). Infection with Beauveria bassiana significantly decreased the different haemocytes count in both fifth nymphal instar and adults, especially after 72h post-infection. The haemocytes’ response against fungi was also investigated. A significant increase in Alpha esterase (EST), Acid phosphatise (ACP) and Alkaline phosphatise (ALP) were observed after 72h post infection in the haemolymph of N. viridula adults. In contrast, phenoloxidase activity significantly decreased in adults’ hemolymph after the same period of infection. Results indicated that infection with B. bassania affects the number of circulating haemocytes and decreases phenoloxidase activity.","PeriodicalId":15069,"journal":{"name":"journal of biopesticides","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45040851","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}

In view of the known antifungal properties of plant extracts, an attempt has been made in the present investigation to explore the Antifungal Activity of Plant extracts against growth of A. flavus by some wild plants of family Asteraceae, viz., Ageratum conyzoides, Carthamus oxycantha, Eclipta alba, Echinops echinatus, Launea nudicaulis, Lactuca dissecta, Parthenium hysterophorus, Sonchus aspera, Vernonia cinerea and Xanthium strumarium have been studied against growth of toxigenic strain of A. flavus by standard cup method on solid medium. The diameter of zone of inhibition was measured in mm and percent inhibition in growth was calculated. Out of three concentrations viz., 10, 15 and 20 per cent of leaf extracts, the 20 per cent concentration was found most effective. Further, hot water extract of leaf was adjudged more inhibitory as compared to cold water extract of plants. The maximum inhibition (70%) in growth of test fungus was caused by hot water leaf extract of A. conyzoides. It also can be concluded that leaf extract of different experimental plants have antifungal activity to varying extents.","PeriodicalId":15069,"journal":{"name":"journal of biopesticides","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46060631","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}
