Abstract In an attempt to control the mosquito-borne diseases yellow fever, dengue, chikungunya, and Zika fevers, a strain of transgenically modified Aedes aegypti mosquitoes containing dominant lethal gene has been developed by commercial company, Oxitec Ltd. If lethality is complete, releasing this should only reduce population size not affect genetics target populations. Approximately 450 thousand males were released each week for 27 months in Jacobina, Bahia, Brazil. We genotyped release...
New techniques and methods are being sought to try win the battle against mosquitoes. Recent advances in molecular have led development of new innovative mosquito control based around Sterile Insect Technique (SIT)1-3. A method known as RIDL (Release Insects carrying a Dominant Lethal)4, is SIT, but uses genetic remove need for radiation-sterilization5-8. strain Ae. aegypti was successfully tested field Grand Cayman9,10; further use planned or progress other countries world. Mass rearing...
Genetic control methods of mosquito vectors malaria, dengue, yellow fever, and Zika are becoming increasingly popular due to the limitations other techniques such as use insecticides. The sterile insect technique is an effective genetic method manage populations. However, it crucial release mosquitoes by air ensure homogeneous coverage, especially in large areas. Here, we report a fully automated adult system operated from uncrewed aerial vehicle or drone. Our system, developed tested...
Ceratitis capitata is one of the most important pests fruits for exportation, and Sterile Insect Technique (SIT) has been efficient environmental friendly technique used to control fruit fly populations around world. A key goal in achieving a successful SIT program mass rearing system producing high quality insects at low cost. Providing adults with an artificial diet containing hydrolysed protein major obstacle bio-production facilities Brazil, because it expensive be imported. Two other...
Abstract The number of mosquito populations resistant to insecticides is increasing along with the reemerging vector‐borne diseases. New technologies are under evaluation complement strategies used against these mosquitoes. Transgenic mosquitoes one approach that some countries considering and they being evaluated control wild population. Although have achieved success in population suppression A edes aegypti (L.) ( D iptera: C ulicidae), studies not demonstrated what outcomes when releases...
The sterile insect technique (SIT) application, as an alternative tool for conventional mosquito control methods, has recently gained prominence. Nevertheless, some SIT components require further development, such protocols under large-scale conditions, focusing on packing and shipping mosquitoes, considering transporting time. Immobilization of Aedes aegypti males was tested at temperatures 4, 7, 10, 14 °C, each temperature assessed 60, 90, 120 min. recovery after 24 h also studied. Chilled...
Abstract The success of the sterile insect technique ( SIT ) depends on ability males to compete effectively with wild mate females. This study compared sexual competitiveness and other behavioral parameters two strains C eratitis capitata W iedemann) D iptera: T ephritidae), tsl Vienna 8 (tsl V‐8) transgenic line OX 3864A, in competition from São Francisco Valley region Bahia, Brazil. Mating events were observed field cages containing virgin, sexually mature insects as follows: 50 females...
Studies investigating oviposition preference of Ceratitis capitata (Wiedemann, 1824) in table grapes (Vitis vinifera L.) cultivated the São Francisco River Valley can provide important information to guide control measures, therefore minimizing damage caused by this species region. The aim study was evaluate C. females for berries cv. 'Italia' collected at five different times (60, 70, 80, 90, and 100 d after production pruning [DAPP]), representing grapevine growth stages. We also assessed...

the Editors were alerted to concerns regarding interpretation of data and some conclusions.Specific include:-the title does not make it clear that authors only examined genomes specimens lacked transgenes sampled during release period;-the Abstract Introduction use language which is justified given evidence present in peer reviewed literature presented this Article.No sampling for study was conducted more than a few weeks after program, as such there no Article establish whether...
Abstract The aim was to evaluate the effect of different energy diets available in adulthood on longevity, dispersal capacity and sexual performance Aedes aegypti produced under a mass-rearing system. To effects relation survival adult male insects Ae. , six treatments were used: sucrose at concentration 10%, as positive control (sack10); starvation, negative (starvation); 20% associated with 1 g/l ascorbic acid (sac20vitC); wild honey 10% (honey10); demerara sugar (demerara10); 0.5 amino...
Sterile males (SMs) of C. capitata have been proposed as vectors entomopathogenic fungi (EF). However, they are also susceptible to virulent strains. This work evaluates the effects supplementing artificial diet with antimicrobial compounds on larvae and adults tsl Vienna-8 their resistance EF Even a lower dose methylparaben (MPB) (0.5 g kg-1) inhibited mycelial growth Metarhizium anisopliae LCB255 Beauveria bassiana LCB289. Sodium benzoate (BNZ) at 2.5 kg-1 reduced both strains by 50%,...
The Aedes aegypti (Linnaeus, 1762) (Diptera: Culicidae) is a mosquito vector of arboviruses that infect millions people around the world annually. In search for new compounds with larvicidal or insecticidal potential, in silico approaches involving computational chemistry tools have become promising methods, providing molecular viewpoint this process. Sterol Carrier Protein type 2 (SCP-2) A. has function carrying out intracellular transport cholesterol and its inhibition can cause lethal...
