“…In Figure 1, we found that the trend of egg number during the month was very significant starting in the week 10. The rainfall received consecutively between week 11 to 18 allowing adult mosquitoes to produce eggs because the rainfall might provide the breeding sites [8]. Although, the frequency of receiving rain in the next week is low but the number of eggs continue to increase.…”

“…Et can be calculated by using the information in Table 1 obtained from our previous studies(referred [7]; [8]).

“…Using the same mathematical model, the population of adult Aedes aegypti was also simulated because the adult is the main life stage of mosquito which involved in both transmitting virus and reproducing egg. A model proposed in previous research [6]; [7]; [8] will be considered and discussed in order to achieve the objectives of this research. We focused on Shah Alam city since the reported cases of dengue are always high and only first three months in 2016 was considered because these months have high dengue cases compared to others period.…”

Aedes aegypti is primary vector of Zika virus, dengue, and chikungunya which go through four different stages of life cycle: Egg, Larva, Pupa, and Adult. The mosquito might be able to lay 100 eggs at a time. The eggs can hatch when there is water and submerged in the water, but it can survive without water almost to 8 months by sticking to the walls of a container. In this research, the trend of egg hatching was simulated by using a stage-structured Lefkovitch matrix model. The matrix model consists of a function of egg hatching which associated and depends on rainfall distribution. The purpose of the function is to identify the relationship between egg hatching and rainfall which provide water to egg. Using the same mathematical model, the population of adult Aedes aegypti has also simulated which the population related to egg simulation and rainfall. The graphical results were shown to illustrate the relationship between the rainfall, egg number and adult Aedes aegypti. We found that there was a significant relationship between the rainfall and these two stages of mosquito life cycle which are egg hatching number and adult Aedes aegypti. However, it is recommended to look for more possible factors such as the size of an opening container and humidity which possible to contribute to the development of mosquito to acquire more accurate results. Contribution/Originality:The study contributes in the existing literature which stated that both factor rainfall and temperature involved in the development of mosquito life cycle. We found that, the rainfall distribution factor is the most significant to identify the trend of development of mosquitos' population and meanwhile the factor of temperature influences more on the increase of dengue virus transmission. body and legs. The infected female Aedes aegypti can spread dengue virus mainly through the bites [2]. The transmission occurs when the mosquito bites a person who already gets infected by dengue fever and the virus will

“…The mosquito life cycle is a complete metamorphosis, comprised of four stages: egg, larvae, pupae and adult. An entire cycle will require approximately two weeks and is highly dependent on temperature and availability of water [ 9 ]. A female mosquito typically lays three to five batches of eggs throughout her lifespan of two to four weeks [ 10 , 11 ].…”

Alphaviruses are arthropod-borne viruses and are predominantly transmitted via mosquito vectors. This vector preference by alphaviruses raises the important question of the determinants that contribute to vector competence. There are several tissue barriers of the mosquito that the virus must overcome in order to establish a productive infection. Of importance are the midgut, basal lamina and the salivary glands. Infection of the salivary glands is crucial for virus transmission during the mosquito’s subsequent bloodfeed. Other factors that may contribute to vector competence include the microflora and parasites present in the mosquito, environmental conditions, the molecular determinants of the virus to adapt to the vector, as well as the effect of co-infection with other viruses. Though mosquito innate immunity is a contributing factor to vector competence, it will not be discussed in this review. Detailed understanding of these factors will be instrumental in minimising transmission of alphaviral diseases.
