The CHCs act as sex pheromones, cell communicators, inhibits dissection, and chemotaxonomic cues. The CHCs were isolated from non-Drosophila species Phorticella striata (Sajjan and Krishnamurthy, 1975) (Diptera, Drosophilidae) by employing whole body extract through GCMS method. Among the identified organic compounds, a total of 38 compounds were obtained from male flies and 68 organic compounds were isolated from female flies, Majority of the CHCs identified were methyl branched alkanes, some of them were esters and alcohols. Male flies exhibit 15 specific CHCs in which tetradecane, 2, 6, 10-trimethylwas dominant with a relative abundance (15.60%) and cyclopropane tetradecanoic acid was the least found CHCs with a relative abundance (RA) of 0.75 per cent. The flies exhibit 28 female specific CHC‘s, among them tetradecane was dominant (r value of 19.20%) and Iodomethyl undecane was the least (RA=0.70%). Both male and female flies shared 23 CHCs, but the ratio among them showed great variance. Among the shared CHCs 3-Trifluoroacetoxy dodecane was dominant in female (RA=14.50%), the male exhibited RA of 4.66 per cent. In male flies 3-Trifluoroacetoxy pentadecane was most abundant CHC (RA=10.90%), than female (4.31%).","PeriodicalId":87603,"journal":{"name":"Entomon; internationale Zeitschrift fur die gesamte Insektenkunde","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84951125","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}

Results revealed that cultivars having indeterminate growth, yellow flower, light green and short pods as well as long peduncle recorded lower pod borer population. Correlation between different plant morphological characters and the larval population were found non-significant. The cultivars having low protein, high phenol and low total soluble sugars in flowers and immature pods recorded lower the larval population. The correlation between biochemical components of flowers and larval population were found to be non-significant. Biochemical components of immature pods revealed that phenol exhibited significant negative relationship with larval population, whereas, correlation of total soluble sugars of immature pods exhibited significant positive association with larval population. Among the cultivars screened, GC-6 and GC-1605 were found to be consistently resistant based on different morphological and biochemical factors and pod borer infestation. Relatively GC-1609, GC-1611 and GC-2 showed lesser pod borer infestation. GC-1606 was found to be highly susceptible.","PeriodicalId":87603,"journal":{"name":"Entomon; internationale Zeitschrift fur die gesamte Insektenkunde","volume":"89 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83441658","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}

Nine insecticide formulations, either solely or in combinations were applied in the rice (var. Lalat) field for two consecutive seasons during 2019-2021 to assess their efficacy to suppress YSB population and to stabilize yield. The combination of flubendiamide (480 SC) @80 g a.s.ha-1 on 45 DAT and deltamethrin (1%) + triazophos (35%) @300 g a.i.ha-1 on 80 DAT, treated the rice crop, recorded minimum YSB incidence (4.14 egg clutches, 4.78 larvae and adults 3.17/5 hills) and damage (2.12% dead hearts (DH) and 1.47 white ear (WE). This treatment gave significantly higher grain yield (3.63 t ha-1), an increase of 45.78 per cent over control. The incidence (12.21 egg clutches, 14.12 larvae and adults 11.76/5 hills) and crop damage (14.83 DH and 11.10% WE) was maximum in the treatment, neem seed kernel extract (5%) @50 ml L-1 at 15 day intervals after transplanting and neem leaf extract (5%) @7 ml a.s.
