Background The combination of Wolbachia -based incompatible insect technique (IIT) and radiation-based sterile (SIT) can be used for population suppression Aedes aegypti . Our main objective was to evaluate whether open-field mass-releases w AlbB-infected Ae males, as part an Integrated Vector Management (IVM) plan led by the Mexican Ministry Health, could suppress natural populations in urbanized settings south Mexico. Methodology/Principal findings We implemented a controlled...
Abstract Dung beetles provide recognised environmental services in cattle production systems, but can be negatively affected by the pharmaceutical residues found excreta, particularly macrocyclic lactones ( ML ). The diversity and seasonal abundance of dung beetle communities were measured using baited pitfall traps compared at four ranches Yucatan, Mexico, to assess possible effects residues. Cattle parasite control was performed two these . A total 93 274 from 17 species collected....

Native bee community diversity is known to vary temporally in the Neotropics, but little research has been done quantify extent of this variation. We studied monthly variation native tropical semi-deciduous forest on Yucatan Peninsula, Mexico, over a twelve-month period 2007. Hurricane Dean traversed study area August that year, causing some changes environment and community. A total 2,335 individual specimens were collected, belonging 102 species from four families. The family Apidae had...
Background The integration of house-screening and long-lasting insecticidal nets, known as insecticide-treated screening (ITS), can provide simple, safe, low-tech Aedes aegypti control. Cluster randomised controlled trials in two endemic localities for Ae . south Mexico, showed that ITS conferred both, immediate sustained (~2 yr) impact on indoor-female infestations. Such encouraging results require further validation with studies quantifying more epidemiologically-related endpoints,...
Abstract Two bioassays were conducted in parallel to assess the effects of cattle treated with either 1% ivermectin (IVM) or 3.15% IVM (dosed at 0.2 and 0.63 mg kg −1 , respectively) on reproduction survival Onthophagus landolti Harold. Adult beetles exposed 10 days faeces starting at: one day before treatment (controls), 3, 6, 14, 28 35 post-treatment. O. was not affected by two treatments. Faecal residues almost completely suppressed fecundity 6 14 post-treatment (dPT), reduced dPT (...
Scarabaeinae are sensitive to structural habitat changes caused by disturbance. We compared copronecrophagous beetle (Scarabaeinae) community structure in three differently managed zones within an agroeco-system of the northern Yucatan Peninsula, Mexico. placed dung and carrion traps once a month from June 2004 through May 2005.
