insect growth regulators for pest management”的學(xué)術(shù)報(bào)告,。吳楚芬教授主持學(xué)術(shù)會(huì)議，學(xué)院微分方程方向老師及研究生參會(huì),。整個(gè)學(xué)術(shù)報(bào)告精彩紛呈,，理論與應(yīng)用相結(jié)合，引起了師生熱烈的反響,。

       報(bào)告簡(jiǎn)介：Insect growth regulators (IGRs)
have been developed as effective control measures against harmful insect pests
to disrupt their normal development. This talk is to propose a mathematical
model to evaluate the cost-effectiveness of IGRs for pest management. The key
features of the model include the temperature-dependent growth of insects and
realistic impulsive IGRs releasing strategies. The impulsive releases are
carefully modeled by counting the number of implements during an insect’s
temperature-dependent development duration, which introduces a surviving
probability determined by a product of terms corresponding to each release.
Dynamical behavior of the model is illustrated through dynamical system
analysis and a threshold-type result is established in terms of the net
reproduction number. Further numerical simulations are performed to
quantitatively evaluate the effectiveness of IGRs to control populations of
harmful insect pests. It is interesting to observe that the time-changing
environment plays an important role in determining an optimal pest control
scheme with appropriate release frequencies and time instants. It is based on
joint work with Dr. Yijun Lou.
