Abstract:
Introduction: Emergence of insecticide resistant mosquitoes emphasize on new tools for control of mosquitoes. An innovative method in adult mosquito control is Attractive Toxic Sugar Bait (ATSB). In order to evaluate behavioral responses of mosquitoes to different fruit-based attractive sugar baits (ASB) and various ASB station (resting sites) was conducted in a confined semi-field in Kazerun, south of Iran.
Methods
A mosquito house (270×430×250 cm) with artificial breeding places was developed under the mulberry tree to prevent the direct sunlight. Four types of ASB stations crock pottery, earthenware pot, pit shelter, and wet black box, were settled inside the mosquito house. The ASB consisted in either brown glucose, or juices of dates, peach, mango, cucumber, and plum. Culicidae larvae (Anopheles spp. and Culex spp.) were collected from field and transferred to the artificial breeding places in the mosquito house. They were reared and developed to adult stage. Then the mosquito behaviors, attractiveness to different fruit juices and resting sites were evaluated. Data were subjected to analysis of variance with Tukey’s Test, and where P≤0.05 was significant.
Results and Discussion: The adult mosquitoes were flying freely throughout the mosquito house’ space, their activities started at the beginning of sunset and followed at dark period. All the artificial resting sites were attractive due to suitable and lower changes of ambient conditions but the pit shelter was found the most attractive site (P≤0.05). Sugar feeding activity started with beginning of sunset and reached to peak in early of evening (20-21 p.m) significantly (P≤0.05). We found that fresh dates and peach juices were highly attractive for the mosquitoes (P≤0.05). In conclusion, the shelter pit with dates or peach juices as an ASB looks promising to disseminate toxic compounds including insecticides to mosquitoes. This ASB also can be applied to distribute transgenic bacteria to mosquitoes for paratransgeneisis approach. However, further efforts are needed to improve the ASB with toxicants or transgenic bacteria for mosquito control.
