Eretmocerus mundus Mercet is one of the key natural enemies of bemisia tabaci (Gennadius). In this study, the sublethal effects of LC25 of imidacloprid and field-recommended concentration of buprofezi...
The functional response is a behavioral phenomena defined as the relation between the parasitized host per each parasitoid and host density. This phenomenon can be useful in assessing parasitoid eff...
We constructed a general relationship between prey concentration and absorption efficiency (AE; previously termed assimilation efficiency) in the cosmopolitan calanoid copepod Acartia tonsa. The relat...
In this paper, a predator-prey model with mixed-type functional response is investigated. Sufficient conditions are derived that guarantee the permanence of the system. Meanwhile, when the system is p...
Functional responses of 2 female coccinellid predators, Scymnus levaillanti and Cycloneda sanguinea, to the cotton aphid, Aphis gossypii, at various temperatures were studied under laboratory conditi...
By using a continuation theorem of Mawhin’s coincidence degree , studied a periodic predator-prey system with dispersal and semi-ratiofunctional response, sufficient conditions are obtained for the ex...
In this paper, a class of two species predator-prey model with functional response and harvesting, we consider a stage-structured population model with two life stages, immature and mature; and assume...
We consider a predator prey system with the functional response of the form µ(x) = arctan(ax); a > 0. The main concern in this paper is the existence of limit cycles for such system. A necessa...
A mathematical model of a predator-prey model withIvlev's functional response concerning integrated pest management(IPM) is proposed and analyzed. We show that there exists a stablepest-eradication pe...
The qualitative properties of a predator{prey system with Holling-(n + 1) functional response and a fairly general growth rate are completely investigated. The necessary and sufficient condition to gu...
摘要 The stabilization problem of a kind of prey-predator model with Holling functional response is investigated. By approximate linearization approach, a feedback control law stabilizing the closed-loo...
In this paper, we study the existence and global asymptotic stability of positive periodic solutions of a delayed periodic predator-prey system with Holling II type functional response. By use of the ...
