It can develop on multiple grass hosts but only appears to survive winter temperatures in Texas near the Mexican border, Florida and Louisiana. Because survival and reproduction of aphids is dependent on access to appropriate nutrition and temperatures at which metabolic processes are maintained, we evaluated the growth, reproduction and survival of sugarcane aphids at constant temperatures (5°C,10°C,15°C,20°C,25°C,30°C,35°C) on three known hosts, sorghum, Johnsongrass, and Columbus grass. Longevity, fecundity, number of female nymphs/d, reproductive period in d, and intrinsic rate of increase were measured at 24 h intervals. At temperatures below 10°C and above 30°C, reproduction did not occur on any of the hosts. Longevity was maximal at 15oC and thereafter decreased with increasing temperatures. The intrinsic rate of increase was highest between 15oC and 25°C on all host plants, while maximum fecundity differed by host plant and was greatest on sorghum. For aphids feeding on sorghum, the Weibull and Natural models were used to estimate lower and upper thresholds for development based on daily fecundity. The lower threshold for fecundity was 9oC, while the upper threshold for fecundity was 32oC. These results suggest that sugarcane aphid can use alternate hosts for survival and reproduction, but both low and high temperatures limit its reproductive capacity. Higher temperatures may trigger dispersal, while lower temperatures should limit sugarcane aphid fecundity and survival in most of the US.","PeriodicalId":203930,"journal":{"name":"Current Trends in Entomology and Zoological Studies","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131092756","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}

Currently, vector control remains the most effective method for preventing diseases, particularly carried out with chemical pesticides leading to insecticide resistance in most mosquito populations’ worldwide objective. We evaluated the larvicidal activity and persistence of tablet formulation of the biolarvicide spinosad (NatularTM DT) in ovitraps placed in shade and sunny environments, which established the basis for monitoring. Furthermore, the influence of spinosad on the choice of trap as an oviposition site and the potential of inhibition of hatchability in eggs were assessed methods. Three concentrations 0.21, 0.43 and 0.87 g/L-were used in ovitraps installed and surveyed weekly for immatures results. Spinosad provided 8-17 weeks of control of Aedes spp. larvae. Ovitrap colonization (>90%) and egg density were recorded, indicating no repellent effect of the spinosad conclusion. The results provide evidence that the spinosad tablet formulation has a high persistence and larvicidal activity, particularly under unshaded conditions. Furthermore, the product does not interfere with the choice of the ovitrap as oviposition site by Aedes spp. female and may be indicated as an alternative for use in ovitraps.","PeriodicalId":203930,"journal":{"name":"Current Trends in Entomology and Zoological Studies","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122757571","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}
