RESUMO
ABSTRACT Background: Egg collection traps have been studied to assist in the integrated control of arbovirus vectors. Many enhancements have been made over the years. Methods: This study evaluated the use of a hydrated superabsorbent polymer (SAP) in the egg collection of Aedes aegypti and Aedes albopictus in ovitraps. An experiment was conducted in the laboratory to determine the minimum concentration of the product to be used in traps in the field to prevent the development of larvae into adults. In the field, the use of polymers has been evaluated using a traditional model of ovitraps. The positive ovitrap index and mean number of eggs per trap indicator were calculated. Results: In the laboratory, the larvae did not successfully develop to the adult stage, even at the lowest SAP concentration. In the field, the results showed that ovitraps with SAP proved to be effective for egg collection from both species. It was possible to identify sites with the highest concentration of species and expose the ovitraps for a longer period without larval development. Conclusions: There is a need for studies on the adequacy of this technology for control programs. However, the results showed that ovitraps with hydrogel were potentiated to capture eggs, configuring themselves as another tool for vector control.
RESUMO
ABSTRACT Aedes aegypti is the mosquito that has been most successful in adapting to the anthropic environment and transmitting several viruses to humans as well. The species has three subspecies that can identified by the variations in the color of the abdominal scales. Each subspecies possesses a distinct scale color pattern. Herein, it is described the first register of Ae. aegypti queenslandensis in São Paulo State, Brazil. Both the scale color pattern, and factor involved in the emergence of the local population are discussed, as well as possible epidemiological implications.
