Advances in the study of latitude gradient patterns of non-target effects of biological control.

In recent years, the non-target ingress of biological control have gradually attracted people's attention.
agasicles hygrophila is an effective natural enemy insect that can prevent invasive plant serogos, which also attacks a native plant lotus grass(
temperature is an important factor that limits the distribution of the lotus grass straight-chested armor-jumping population and wintering, and can affect the non-target effect of insects.
study the dynamic changes of insect populations that are not targeted due to climate change can provide a more accurate basis for risk assessment of biological control.
, Under the guidance of researcher Ding Jianqing, Dr. Wang Yan of Wuhan Botanical Garden of the Chinese Academy of Sciences conducted a continuous follow-up survey of the conditions and growth of hollow lotus grass and lotus grass, as well as the population dynamics of jumpers in two plant communities, in three different latitude climate-like areas (Kaifeng, Wuhan and Guilin).
researchers found seedlings of one-year-old lotus grass in Kaifeng, while Wuhan and Guilin had both one-year-old and perennial lotus grass seedlings, but only the survival of lotus grass individuals were found in Guilin in winter.
Guilin's armor-jumping population can maintain the population and successfully winter on the lotus grass, while in the other two sample points, although the jumping armor in the growth season can maintain the population on the lotus grass, but not successful winter.
these results show that in different latitude climate zones, temperature differences can directly (affect winter) or indirect (affecting plant conditions) affect the non-target effect of the jump.
therefore, it is of great theoretical significance and practical value to explore the changes in plant-insect interaction caused by climate differences to guide the prediction of the potential non-target ingenuity of biological control.
research projects, funded by national key research and development projects, are based on Population Dynamics and Overwintering of the a thorace sauer, Agasicles hygrophila, on a nontarget plant alternanthis, long a latitudinal gradient, published in the Journal of The Journal of The Journal of The Journal.
