Its cultivation is seriously hampered by hog- hog plum beetle or 14 spotted leaf beetle, Podontia 14-punctata L. (Chrysomelidae: Coleoptera). In most of the cases, insecticidal spray is not effective for controlling this pest as pupation occurs in the soil. Therefore current study was carried out in both laboratory and field condition to develop environment friendly management approaches against hog plum beetle as well as producing of toxic chemical pesticide free hog-plum. From laboratory test, it is revealed that spraying of spinosad (Success 2.5 SC) at hog plum leaflet and drenching with microbial pesticides, soil recharge namely Lycomax (Metarhizium anisopliae + Trichoderma harzianum + Beauveria bassiana + Trichoderma viride) causes 72.22% adults and 51.85% pupal mortality of P. 14-punctata respectively. Then some pest management modules were developed based on the laboratory result and it’s were verified in field during two fruiting season 2018-19 and 2019-20. From field study it is observed that module 1: Hand picking + trunk banding with packaging tape + soil drenching with lycomax + spraying of spinosad treated trees offered lowest leaf and fruit infestation; even though trunk banding with packaging tape did not show any effect to control this pest. Fruit yield was also increased 39.04-39.66% in module 1 imposing hog plum trees compare to control. Therefore, it is clear that without banding of the hog plum trunk, hand picking + soil drenching with microbial pesticides, lycomax + spraying of spinosad might be sustainable and environment friendly pest management module against P. 14-punctata.","PeriodicalId":15188,"journal":{"name":"Journal of Biological Control","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87056322","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 Trichoderma spp. was isolated on Trichoderma Selective Medium (TSM) and observed that the isolates differed in radial growth and colony characters such as colony colour, texture and sporulation. In vitro studies revealed the potential of Trichoderma isolates against soil borne pathogens. Isolates TRPN3 and TRPN7 exhibited no sporulation and white mycelial colour. Isolates which completed their growth at four days after inoculation include TRKR1, TRPN3, TRPN7, TRPN10 and TRPN18. Biocontrol activities against different pathogens resulted in inhibition of pathogens. Maximum inhibition percentage was observed by the isolates TRPN7, TRPN15 and TRKR2 against both the pathogens. The maximum inhibition exhibited against both the pathogens is due to the antagonistic property displayed by the isolates.","PeriodicalId":15188,"journal":{"name":"Journal of Biological Control","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79046085","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}

GC-MS study was analysed in hexane, ethyl acetate and methanol extract of S. torvum and the leaf extracts yielded around 57 compounds. In the larvicidal and adulticidal tests against A. aegypti, mortality rate increased with the increased concentrations of S. torvum extract. Highest larval mortality was obtained with ethyl acetate 100% extract at the dose of 200 ?g/ml after 48 hrs experiment, followed by methanol 64% and hexane 42% leaf extract. The LC50 values of leaf extract was observed as 159.594 ?g/mL, 182.272 ?g/mL at 24 hrs interval and 85.2833 ?g/mL, 138.472 ?g/mL 48 hrs interval for ethyl acetate and methanolic extracts, respectively. In adulticidal activity highest mortality rate was obtained in ethyl acetate extract at 92% for the dose of 2 mg/ml after 24 hrs, followed by methanol 74% and hexane 52% leaf extracts. The LC50 values were 0.453 mg/mL, 0.790 mg/mL and 1.294 mg/mL with ethyl acetate, methanol and hexane extracts at 24 hrs interval against Aedes aegypti. In control treatment, no mortality rate was observed.
