Abstract


In the last three decades, there has been a four fold increase of dengue incidence globally. Up till now, the control of the disease depends heavily on controlling the vector. Therefore, it is necessary to develop an ecological data of vector to identify the population density of the mosquitoes. One method to study the density and presence of the mosquitoes is through the use of ovitrap. The aim of this research is to identify the effect of two different types of ovitraps: natural and artificial ovitrap on the willingness of mosquitoes to lay eggs and the rate of which the eggs are hatched. One hundred and eighty ovitrap consist of coconut shell (90) and glass (90) ovitrap were placed in three different subdistricts which was selected based on the Incidence Rate of Dengue Haemorrhagic Fever (DHF) in the district of Purwokerto City. The container indices and
eggs density were compared between two types of ovitrap. Research was conducted using experimental quasy and the data were analyzed with the Mann-Whitney test. The total amount of eggs from coconut shell ovitrap were 9328 of eggs were obtain from 51.33 of (57%) ovitrap while the total amount of eggs from glass ovitrap only 1858 of eggs were obtain from 29 (32%) ovitrap. Statistical test showed significant difference between the amount of eggs of coconut shell higher than the glass with p = 0001. Mosquitoes prefer natural coconut shell ovitrap compared with artificial ovitrap so we recommended that to eradicate the mosquitoes nest (PSN) with 3M (closed, drain, bury) should not only artificial containers but also natural container to be managed in order to control the dengue vector.

KEY WORDS: Natural, artificial ovitrap, preference to hatch Aedes sp.
eggs.
