“…Until recently year, the use radioisotopes (gamma-rays) in male mosquito sterilization process of the SIT still being developed. BELLINI et al [52,53] reported mating competitiveness of Aedes albopictus in Rimini, Italy, after gammairradiation on variety dose. The study states that mating competitiveness of Aedes albopictus decreasing on 30 to 60 Gy gamma-irradiation.…”

Filariasis as part of the neglected tropical disease is one of the health problems in the world. Filariasis divided into onchocerciasis (river blindness) and lymphatic filariasis or elephantiasis. This disease caused by filarial nematode parasites Onchocerca volvulus, Wuchereria bancrofti, Brugia malayi and Brugia timori. Filariasis transmitted by several mosquito genera as the vector. Indonesia as endemic filariasis, agreed on plays a role on World Health Organization (WHO) global filariasis elimination in 2020. Sterile insect technique (SIT) is a potential method which can be applied to filariasis elimination program by controlling the mosquito population. Basic principles of SIT involve mass rearing of species target, sterilization process using gamma-rays and releasing sterile male insect into a target area. SIT combined with other methods under one management as Area-wide Integrated Pest Management (AW-IPM) to increasing effectiveness and successful filariasis elimination program in Indonesia. Filariasis elimination program in Indonesia has several challenges and needed public participation to achieve program goals. Key words : filariasis, Indonesia, sterile insect technique (SIT) ABSTRAKFilariasis sebagai bagian dari penyakit tropis yang terbengkalai merupakan salah satu masalah kesehatan di dunia. Filariasis dibagi menjadi onchocerciasis dan filariasis limfatik atau kaki gajah. Penyakit ini disebabkan oleh parasit nematoda filarial Onchocerca volvulus, Wuchereria bancrofti, Brugia malayi dan Brugia timori. Filariasis ditularkan oleh beberapa genera nyamuk sebagai vektor. Indonesia sebagai endemik filariasis, sepakat memainkan peran dalam eliminasi filariasis global yang diagendakan oleh world health organization (WHO) pada tahun 2020. Teknik serangga mandul (TSM) adalah metode potensial yang dapat diterapkan pada program eliminasi filariasis dengan mengendalikan populasi nyamuk. Prinsip dasar SIT melibatkan pembiakan populasi target secara massal, proses sterilisasi menggunakan sinar gamma dan melepaskan serangga jantan steril ke daerah sasaran. TSM dapat dikombinasikan dengan metode lain di bawah satu manajemen terpadu, yaitu area-wide integrated pest management (AW-IPM) untuk meningkatkan efektivitas dan keberhasilan program eliminasi filariasis di Indonesia. Program eliminasi filariasis di Indonesia memiliki beberapa tantangan dan kebutuhan partisipasi masyarakat untuk mencapai tujuan program.

“…In addition to [23], we consider a parameter λ s that indicates the level of fertility of sterile males. In fact, depending on the radiation dose, the sterile male is not necessarily fully sterilized [5,7]: only for doses greater or equal to 40 Gy, Aedes males become fully sterile, i.e. λ s = 0.…”

The aim of this paper is to develop a mathematical model to simulate mosquito dispersal and its control taking into account environmental parameters, like wind, temperature, or landscape elements. We particularly focus on Aedes albopictus mosquito which is now recognized as a major vector of human arboviruses, like chikungunya, dengue, or yellow fever. One way to prevent those epidemics is to control the vector population. Biological control tools, like the Sterile Insect Technique (SIT), are of great interest as an alternative to chemical control tools which are very detrimental to environment. The success of SIT is based on a good knowledge of the biology of the insect, but also on an accurate modeling of the insect's distribution. We consider a compartmental approach and derive temporal and spatio-temporal models, using Advection-Diffusion-Reaction equations to model mosquito dispersal. Periodic releases of sterilized males are modeled with an impulse differential equation. Finally, using the splitting operator approach, and well-suited numerical methods for each operator, we provide numerical simulations for mosquito spreading, and test different vector control scenarios. We show that environmental parameters, like vegetation, can have a strong influence on mosquito distribution and in the efficiency of vector control tools, like SIT.keyword Advection diffusion reaction equation, impulse differential equation, mosquito dispersal, sterile insect technique, operator splitting, nonstan-

“…Subsequently, a more extensive trial took place from 1977 to 1979 on the Pacific coast of El Salvador [32] with up to 0.5 million sterile males or 1.25 million sterile male pupae being released every day. Recently (2007) in Italy, Bellini [10], released sterile males, which contributed to reduce the wild population of aedes albopictus and to fight the Chikungunya virus [17] (see [15,16] for further details about Chikungunya). Furthermore, mosquitos genetically modified by using the RIDL (Release of Insects carrying a Dominant Lethal) Technique, were released in the Caïman Island and in Malaysia, by the Oxitec Company to fight Dengue Fever (see [25] for an overview on RIDL approach for Aedes aegypti ).…”

The Sterile Insect Technology (SIT) is a nonpolluting method of control of the invading insects that transmit the disease. The method relies on the release of sterile or treated males in order to reduce the wild population of anopheles mosquito. We propose two mathematical models. The first model governs the dynamics of anopheles mosquito. The second model, the SIT model, deals with the interaction between treated males and wild female anopheles. Using the theory of monotone operators, we obtain dynamical properties of global nature that can be summarized as follows. Both models are dissipative dynamical systems on the positive cone R 4 + . The value R = 1 of the basic offspring number R is a forward bifurcation for the model of the anopheles mosquito, with the trivial equilibrium 0 being globally asymptotically stable (GAS) when R ≤ 1, whereas 0 becomes unstable and one stable equilibrium is born with well determined basins of attraction when R > 1. For the SIT model, we obtain a threshold numberλ of treated male mosquitos above which the control of wild female mosquitos is effective. That is, for λ >λ the equilibrium 0 is GAS. When 0 < λ ≤λ, the number of equilibria and their stability are described together with their precise basins of attraction. These theoretical results are rephrased in terms of possible strategies for the control of the anopheles mosquito and they are illustrated by numerical simulations.
