• Females three to five days old, not siphoned, are introduced in sets of 11 in the cages.
• a total of 44 females are used to test each sample.
• the tests are conducted at a temperature of between 23 ° C. and 25 ° C. at 50% to 70% relative humidity.
• the observation made during the 24 hours following the introduction of mosquitoes into the cage is carried out at a temperature of 28 ° C. at 70% relative humidity.
• KD is the number of mosquitoes that respond to the effect of the insecticide. The latter show signs of weakening and are unable to sting.
• the treatment consists in applying a chemical composition containing active molecules intended for neutralization odors based on a mixture of geraniol and eugenol on a concrete support.
• the effective concentration of the mixture of geraniol and eugenol to be fixed on the support depends on the concentration of the mixture in the bath, the level of odor to be neutralized and the amount of bath deposited on the support.
• the fixing process consists of:
• a chemical odor neutralization composition is prepared containing: 1. 739 g / liter of a formulation of a mixture of geraniol and eugenol in emulsion at 30%;
• the active element is dried at ambient temperature (between 20 ° C. and 25 ° C.).
• Odor neutralization treatment has been effective for up to 10 weeks.
• the odor neutralization treatment is effective for a maximum duration of 4 to 5 days.
