Larviposition Responses of Aedes Aegypti Mosquito On Fermented Rice Wash (Oryza Sativa) and Fresh Milk

Abstract

INTRODUCTION

Aedes aegypti is a mosquito known as the vector of dengue, a neglected tropical disease ranked by the World Health Organization (WHO) as the most important viral disease transmitted by mosquitoes worldwide. To date, there is no specific vaccine or antiviral drug for the treatment of dengue and only supportive treatment is given to dengue patients. Thus, the search for selective treatment of dengue is still in progress so vector control is the best strategy. To solve this problem, chemical insecticides may be used to control mosquitoes, but most of them are not selective, and harm beneficial insects and humans. For these reasons, the use of organic mosquito attractants must be promoted. Studies have found that Rice wash, mainly composed of carbohydrates and fresh milk containing lactic acid bacteria species when it has undergone carbohydrate fermentation will produce Lactic Acid, a compound commonly found in the human body that naturally attracts mosquitoes.

METHODS

A specific amount of rice wash and fresh milk was fermented one after the other for a total of 14 days. The produced mixtures were then placed inside black plastic cups with lawanit paddles and placed securely inside the classrooms of LNHS -Indang Annex. The attractants were monitored for five (5) days to determine the number of positive attractants and time of attraction.

RESULTS

Treatment 3 was proven the most effective in terms of number of attractants with mosquito larvae and the time it took for an attractant to have mosquito larvae with 69 positive responses and average time of attraction of 2.17 days.

DISCUSSIONS

In terms of characteristics as number of mosquito attractants with mosquito larvae, Treatment 3 was the most effective. Treatment3 was also proven effective in terms of the time it took for an attractant to have mosquito larvae. There is a significant difference in the effectiveness of the mosquito attractants and the treatments in terms of number of attractants with mosquito larvae and the time it took for an attractant to have mosquito larvae.
