Although D. longicaudata has been released in Kenya through the Africa Fruit Fly Programme, the extent of its dispersal and subsequent economic benefits have not yet been established. This paper models the spatio-temporal dispersal of the parasitoid using the fuzzy cellular automata approaches and estimates the net benefit from each dollar invested in the CBC approach. We calculated the return on investment based on funding into the programme between 2006 and 2015 and the result of the dispersal range of the parasitoid predicted using an artificial intelligence algorithm. The investment yielded a significant net present value of US$42.8 million over the 16 years. Besides, the cost–benefit ratio showed that for every US$1 invested, the return benefit was US$93 , confirming the profitability of the CBC program. The economic gains are significant considering that there is no environmental contamination and possible adverse effects from the CBC intervention. The study findings support investment in biological control strategies for the eco-friendly and area-wide management of B. dorsalis.","PeriodicalId":8878,"journal":{"name":"BioControl","volume":"24 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135973434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the application of Bacillus velezensis PHP1601 (Bacillales: Bacillaceae) treatments (10 5 and 10 10 endospore g −1 ) to pig manure slurries was evaluated as a means of controlling fly reproductive cycles. Two cycles of fly emergence were evaluated over a 33 days period for each replicated trial. For both treatments, the first emergence event resulted in a significant reduction in the percentage of flies emerging compared to an un-treated control. Extended monitoring of the biocontrol containers revealed that fly emergence was completely eliminated by the time that a second round of fly emergence was observed for the control. A B. velezensis -specific real-time PCR method was developed and used to assess the population dynamics of the applied biocontrol agent over the course of the experiment. Strain PHP1601 remained viable in the manure and cell numbers increased by several orders of magnitude. REP-PCR fingerprinting was used to confirm the clonality of endospores recovered from the manure. Fly species recovered from the trials were identified by cytochrome oxidase gene barcode sequencing. Several species of veterinary and medically significant flies were identified. They were all deemed to be susceptible to treatments with PHP1601 and constituted part of the strain's host range. The study demonstrated the effectiveness of B. velezensis PHP1601 as a promising biocontrol agent for controlling fly infestations under conditions similar to its intended use.","PeriodicalId":8878,"journal":{"name":"BioControl","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136068506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
