4.In this paper, predator-prey systems with periodic impulsive effect concerning pest control are proposed through biological control and chemical control.
5.In this paper,a classical periodic two prey and a predator predator-prey system with impulsive effect is investigated.The boundedness of system and the local stability of trivial or semi-trivial periodic solution are proved by using comparative theorem and multipliers theory of impulsive differential equation.A set of sufficient conditions are derived for the existence of at least one positive periodic solution,by using the method of coincidence degree.
6.This note studies two-species metapopulations dynamics com mon model considering of the affect of interspecific interaction to colonization and extinction rate and rescue effect,demostrates the conditions of two specie s capable of coexistence in the competitor,predator-prey or mutualist system.
7.Both Oxyopes sertatus and Harpactor fuscipes are important predators of common cutworm (Spodoptera litura) on tobacco.The effect of several interference factors on the predations of O.sertatus and H.fuscipes on the larvae of S.litura were examined in laboratory.The results indicated that there were significant mutual interferences on their predations with the existence of other individual in the same/different species.As the number of the predator increased,the predation rates decreased significantly.The interference coefficients (m) within H.fuscipes and within O.sertatus were 0.7278 and 0.6911,respectively,while the interference coefficient (m) between O.sertatus and H.fuscipes was 0.9464.These results showed that the effect of mutual interference on predation in interspecies was more obvious than that in intraspecies.The number of prey captured and the predation rate of predator dropped with increasing the number of tobacco stalks.This result suggested that spatial heterogeneity was also an important factor affecting the predation of predator on prey.
