1. Quality control and characterization of the testicles and ovaries of irradiated Anastrepha obliqua from Brazil
ABSTRACT: With the aim of making the application of the Sterile Insect Technique (SIT) feasible in the management of the West Indian fruit fly in Brazil, Anastrepha obliqua (Macquart) (Diptera: Tephritidae), a number of quality parameters required by the SIT were investigated in this study. The aim was to verify the influence of a range of doses of gamma rad

2. Viruses vector control proposal: genus Aedes emphasis
Abstract The dengue fever is a major public health problem in the world. In Brazil, in 2015, there were 1,534,932 cases, being 20,320 cases of severe form, and 811 deaths related to this disease. The distribution of Aedes aegypti, the vector, is extensive. Recently, Zika and Chikungunya viruses had arisen, sharing the same vector as dengue and became a huge

3. Adding guarana powder to medfly diets: an alternative for improving the Sterile Insect Technique
ABSTRACT Ceratitis capitata (medfly) is a globally important horticultural pest that can be controlled using the sterile insect technique (SIT), but the success of SIT depends on the sexual performance of mass-reared males when released into the field. We added “guarana” (Paullinia cupana) powder (derived from an Amazonian fruit that is considered to be

4. Large scale artificial rearing of Anastrepha sp.1 aff. fraterculus (Diptera: Tephritidae) in Brazil
Some species of the genus Anastrepha (Diptera: Tephritidae) are successfully managed by matching the sterile insect technique with parasitoid releases. Such strategies used in integrated pest management can be implemented only where insect mass-rearing programs are feasible. In this study, we show the process of domestication, rearing technology and quality

5. Large indoor cage study of the suppression of stable Aedes aegypti populations by the release of thiotepa-sterilised males
The sterile insect technique (SIT) is a promising pest control method in terms of efficacy and environmental compatibility. In this study, we determined the efficacy of thiotepa-sterilised males in reducing the target Aedes aegypti populations. Treated male pupae were released weekly into large laboratory cages at a constant ratio of either 5:1 or 2:1 steril

6. Mass-rearing of Mediterranean fruit fly using low-cost yeast products produced in Brazil
Ceratitis capitata is one of the most important pests of fruits for exportation, and Sterile Insect Technique (SIT) has been the most efficient and environmental friendly technique used to control fruit fly populations around the world. A key goal in achieving a successful SIT program is a mass rearing system producing high quality insects at low cost. Provi

7. Chilled packing systems for fruit flies (Diptera: Tephritidae) in the sterile insect technique
We evaluated three packing systems (PARC boxes, "GT" screen towers and "MX" screen towers) for the emergence and sexual maturation of sterile fruit flies, at three adult fly densities (1, 1.2 and 1.3 fly/cm²) and three food types. At the lowest density, results showed no significant differences in the longevity and flight ability of adult Anastrepha ludens

8. Criação massal em dieta líquida e radioesterilização da mosca-sul-americana Anastrepha sp.1 aff. fraterculus (Wied., 1830) (Diptera: Tephritidae) / Mass production in liquid diet and radioesterilização of South American fruit fly Anastrepha sp.1 aff. fraterculus (Wied., 1830) (Díptera: Tephritidae)
Tanto as técnicas de controle biológico quanto a Técnica do inseto estéril (TIE), são utilizadas em vários países para o controle, supressão e até mesmo erradicação de moscas-das-frutas e outras pragas da agricultura, pecuária e saúde publica. O uso de tais técnicas minimiza o emprego contínuo de inseticidas, protege o ambiente e se adequa aos

9. Influência da recópula de fêmeas selvagens de Ceratitis capitata (Wied., 1824) (Diptera: Tephritidae) na eficiência da técnica do inseto estéril / Influence of wild Ceratitis capitata (Wied., 1824) (Diptera: Tephritidae) females remating on the efficiency of the sterile insect technique
The sterile insect technique (SIT) aim at the induction of sterility in wild females by mating with sterile males released in great amounts in the field. These released males must compete with wild ones being able to attract and mate wild females, fertilize their eggs and avoid remating with a wild male that would lead to fertile eggs and consequently reduce

10. Sterilization of fruit flies (Diptera: Tephritidae) with X-rays for Sterile Insect Technique Programs / Esterilização de moscas-das-frutas (Diptera: Tephritidae) com raios-X para Programas de Técnica do Inseto Estéril
Recent fear of acts of terrorism provoked an increase of delays and denials in the shipment of radioisotopes. This truly represented a menace to sterile insect production projects around the world. In order to validate the use of a new kind of low-energy X-ray irradiator, a series of radiobiological studies on Ceratitis capitata (tsl-VIENNA 8 strain) (Wied.,

11. Controle genético de mosquitos Culex quinquefasciatus / Genetic control of Culex quinquefasciatus mosquitoes
The Culex quinquefasciatus mosquitoes are considered urban plague and are able to grown in polluted water achieving high density. This specie are important vectors in the transmission of parasites and arbovirus. Chemical control methods shown to be ineffective and highly hazards to the environment. In this way, new technologies of control have been developed

12. Optimal control theory applied to assess the control of Aedes aegypti by sterile insect technique and insecticide / Controle otimo aplicado na estrategia de combate ao Aedes aegypti utilizando inseticida e mosquitos estereis
O ciclo de mosquitos é dividido em dois estágios: fase aquática (ovos, larvas e pupas) e fase alada (mosquitos adultos). Apresentamos um modelo de controle ótimo de mosquitos que consiste na introdução de mosquitos machos estéreis obtidos pela técnica de irradiação. Nosso modelo é baseado em equações diferenciais ordinárias que descrevem a din�
