Mentha piperita L. and Salvia officinalis L., as green pesticides were incorporated into Poly Lactic Acid (PLA) solution about 14%wt which were successfully electrospun into mats with ∼58 nm fiber diameters. The contact toxicity of essential oils (EOs) was tested on first instar larvae of Plodia interpunctella after 72-h to evaluate the effect of PLA nanofibers loaded with the EOs versus the pure essential oils (PEO)s on the mortality of the larvae over one month. The comparison between LC50 of the formulated essential oils (NFO)s and PEOs showed a significant difference (p< 0.05). The NFOs showed higher contact toxicity than the PEOs to control this pest for a longer time with slow release efficiency. Moreover, M. piperita showed more toxicity than S. officinalis. The nanofibers cause surface tension. Therefore, it is evaluated that this formulation increases the contact toxicity efficiency of essential oils as green contact pesticide.

There is a dire need of research regarding species composition, distribution pattern so that their role in controlling insect pests could be ascertained. Present study examined a novel approach for documenting the diversity of spider fauna in arid and semi- arid (Ajmer and Jodhpur) region of Rajasthan, India. A regular survey of spider faunal complex was conducted in four major habitats namely, woodland, wetland, pasture and caves/crevices/rocky area. Maximum number of spiders was found in woodland habitat and the minimum number of spiders were collected and identified from caves/crevices/rocky area with 31.86 and 17.61 relative abundance, respectively. Similarly, diversity indices viz., richness, evenness, Shannon-Weiner and Simpson indexalso indicated the maximum species richness in woodland and minimum in caves/crevices/rocky area. In woodland, Araneidae and Oxyopidae were found as most abundant families with 41.44 and 15.78 percent of total spider fauna while Lycosidae wasfound as the most abundant family in wetland but was at par with Araneidae in pasture habitats. In Caves/crevices/rocky area, family Pholcidae was found as the most abundant.","PeriodicalId":15069,"journal":{"name":"journal of biopesticides","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44893458","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}

Wiltshire. This disease is one of the most significant destructive pathogens to vegetable crops in Thailand and Southeast Asia. Disease management of these pathogens is done by using synthetic fungicides which are expensive and harmful to the environment. This study aimed to investigate the efficacy of the extracts from five plants, Hydnocarpus anthelminthicus Pierre ex Laness., Crateva magna (Lour.) DC., Caesalpinia sappan L.,Xanthophyllum lanceatum J. J. Sm., and Carallia brachiata (Lour.) Merr. to control the Chinese kale leaf spots caused by A. brassicicola in in vivo condition. In an in vivo test, we found that the plant extracts of C. brachiata, H. anthelminthicus, X. lanceatum and C. magna showed a potential in control efficacy against brassica dark leaf spots caused by A. brassicicola. The four plant extracts effectively suppressed the development of leaf spots at a concentration of 10,000 ppm and 50,000 ppm at 30 DAT. However, at 40 DAT the C. magna and H. anthelminthicus extracts strongly inhibited A. brassicicola at concentrations of 10,000 ppm and 50,000 ppm respectively when compared with the water control. This is the first report demonstrating that the plant extracts collected from riparian forest can provide control against brassica dark leaf spots disease. Based on our study, we demonstrated that the ability of plant crude extracts can be used as natural fungicides to control Chinese kale leaf spots and replace synthetic fungicide.","PeriodicalId":15069,"journal":{"name":"journal of biopesticides","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45488033","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 survival, development and multiplication of the immature stages are determined by different interdependent factors. The application of manures and fertilizers in agro-ecosystem is one of the important factors. A laboratory study was conducted to evaluate the impact of inorganic fertilizer (DAP and UREA 1:1/2 ratio), organic fertilizer (cow dung) and green algae (Spirogyra) against immature An. gambiae. The experiment includes three doses of inorganic fertilizer, cow dung and green algae in 1 L of deionised water prepared in a square tray and 1 L of deionised water alone was considered as control. In the experiment and control group twenty five I, II, III and IVth instar larva was released into individual tray and monitored every 24 h till the completion of their life cycle. The numbers of surviving larval stage was recorded continuously until all the larvae died or emerged into adults. The experimental result revealed that in the case of the tray mixed with 0.75g/L of inorganic fertilizer, the number of adults that emerged from four different larval instar stages was statistically significant (p < 0.05). The number of adults that emerged in high turbidity green algae filament treatment was 95.61 ± 3.86, 93.85 ± 3.30, 90.5 ± 5.43 and 86.84 ± 4.78 from I, II, III and IVth instar larvae respectively.
