“…However, more efficient male and female separation technology is the focus of further research. In addition, to obtain the most benefit, the timing of the release of the mosquitoes may also need to be considered, although there have been fewer studies along these lines ( Huang et al, 2020 ).…”

Malaria is still the most widespread parasitic disease and causes the most infections globally. Owing to improvements in sanitary conditions and various intervention measures, including the use of antimalarial drugs, the malaria epidemic in many regions of the world has improved significantly in the past 10 years. However, people living in certain underdeveloped areas are still under threat. Even in some well-controlled areas, the decline in malaria infection rates has stagnated or the rates have rebounded because of the emergence and spread of drug-resistant malaria parasites. Thus, new malaria control methods must be developed. As the spread of the Plasmodium parasite is dependent on the part of its life cycle that occurs in mosquitoes, to eliminate the possibility of malaria infections, transmission-blocking strategies against the mosquito stage should be the first choice. In fact, after the gametocyte enters the mosquito body, it undergoes a series of transformation processes over a short period, thus providing numerous potential blocking targets. Many research groups have carried out studies based on targeting the blocking of transmission during the mosquito phase and have achieved excellent results. Meanwhile, the direct killing of mosquitoes could also significantly reduce the probability of malaria infections. Microorganisms that display complex interactions with Plasmodium, such as Wolbachia and gut flora, have shown observable transmission-blocking potential. These could be used as a biological control strategy and play an important part in blocking the transmission of malaria.

In this paper, we extend existing population growth models and propose a model based on a nonlinear cubic differential equation that reveals itself as a special subclass of Abel differential equations of first kind. We first summarize properties of the time-continuous problem formulation. We state the boundedness, global existence, and uniqueness of solutions for all times. Proofs of these properties are thoroughly given in the Appendix to this paper. Subsequently, we develop an explicit–implicit time-discrete numerical solution algorithm for our time-continuous population growth model and show that many properties of the time-continuous case transfer to our numerical explicit–implicit time-discrete solution scheme. We provide numerical examples to illustrate different behaviors of our proposed model. Furthermore, we compare our explicit–implicit discretization scheme to the classical Eulerian discretization. The latter violates the nonnegativity constraints on population sizes, whereas we prove and illustrate that our explicit–implicit discretization algorithm preserves this constraint. Finally, we describe a parameter estimation approach to apply our algorithm to two different real-world data sets.

The field trial of mosquito population suppression in Guangzhou showed that the migration of wild mosquitoes to the target area were resistant to elimination. In this work, we formulate a delay differential equation model to assess the impact of migration on the suppression efficiency, and identify that the migration of wild mosquitoes from surrounding area excludes the possibility of a complete population suppression. Our analysis identifies a lower bound of the suppressed population size, and a lower bound of the suppression rate γ * , which reveals the possible maximum reduction of field mosquitoes in the peak season. For a given suppression rate target γ 0 > γ * , we identify the permitted maximum migration number D(γ 0 ), above which is impossible to reduce the field mosquito density up to (1 − γ 0 ) × 100% in peak season. To reduce more than 95% of Aedes albopictus population during its peak season in Guangzhou within six weeks, the required minimum release number climbs steeply as the migration number increasing near to D(0.05).
