An effective dried attractive toxic bait station that acts as a lure and kill device for Ae. aegypti and other mosquitoes. The bait station is a simulated refuge at least part of which is coated with a dried mixture of poison and sugar forming a dried toxic sugar-containing bait. The simulated refuge attracts Ae. aegypti and other mosquitoes to bait station and encourages them to land on the coated portion. Once a mosquito has landed, it detects the sugar in the dried mixture of sugar and poison and ingests some of it. Once ingested, the dried mixture of poison and sugar will eventually kill the mosquito.

Within the unique Triplo-lethal region (Tpl) of the Drosophila melanogaster genome we have found a cluster of 20 genes encoding a novel family of proteins. This family is also present in the Anopheles gambiae genome and displays remarkable synteny and sequence conservation with the Drosophila cluster. The family is also present in the sequenced genome of Drosophila pseudoobscura, and homologs have been found in Aedes aegyptii mosquitoes and the honeybee (Apis mellifera), but it is not present in the sequenced genome of any non-insect species. Phylogenetic analysis suggests that the cluster evolved prior to the divergence of Drosophila and Anopheles (250MYA) and has been highly conserved since. The ratio of synonymous to nonsynonymous substitutions and the high codon bias suggest that there has been selection on this family both for expression level and function. We suggest that this gene family is Tpl, name it the Osiris family, and suggest possible functions. We also suggest that this family of proteins, due to the unique dosage sensitivity, and the lack of homologs in non-insect species, would be a good target for genetic engineering or novel insecticides. The proteins also present an excellent means to test compounds for use as possible insecticides.

The invention discloses application of an iron-containing substance to preparation of a product for inhibiting dengue virus propagation. The invention firstly discloses the application of the iron-containing substance to preparation of a product for inhibiting dengue virus propagation and / or inhibiting susceptibility of mosquitoes to dengue viruses. The invention further discloses a method for inhibiting dengue virus preparation and / or inhibiting susceptibility of the mosquitoes to the dengue viruses. According to the invention, experiments prove that hosts in different iron states, who are infected by the dengue viruses and bitten by aedes aegypti, have remarkably different virus infection rates, and the susceptibility of the aedes aegypti to the dengue viruses is remarkably negatively correlated with the iron state of the host blood. Further, the susceptibility of the aedes aegypti to the dengue viruses can be effectively reduced by supplementing iron to an iron-deficiency mouse model, which shows that the iron-containing substance can reduce the virus carrying capacity of the aedes aegypti and block propagation of the viruses in nature.
