【摘要】：梨小食心虫是一种林果生产上的重要害虫。做到科学防治梨小食心虫,就要在预测预报环节上做到及时准确,准确估计虫口数量是测报的基础。然而当前梨小食心虫的诱捕统计工作费时费力,测报工作容易发生滞后,各地植保相关部门对梨小食心虫的预测预报工作缺乏成熟有效的预测预报系统,因此,为了减轻梨小食心虫调查的难度,提高调查的效率和准确性,本研究通过带有性诱芯和自动计数系统的诱捕器采集目标昆虫,结合相关模型的预测特点,建立基于We系统,该系统实时快速上报梨小成虫虫口数据,并完成对梨小食心虫成虫的自动采集、统计、查询、测报功能,从而提高其测报效率与水平。本研究最终同时对保定一桃园梨计数系统的监测数据对当地梨小食心虫的发生期计算出初步预测值。主要结论如下:(1)水盆式和桶型诱捕器的诱捕效果好于蓝色粘虫板和自制水瓶诱捕器,四种诱捕器依次按序诱捕到:1 293头、949头、489头和153头;(2)水盆诱捕器和桶型诱捕器不仅可以作为梨小发生动态的指示,而且可以减轻梨小对果园的危害程度。(3)发生规律:保定满城坨南地区2014年梨小1年出现3个危害高峰分别是六月下旬、七月中下旬、八月下旬;(4)诱捕自动计数系统统计结果与实际调查结果有一定误差,个别调查数据因服务器异常及下雨天气影响导致与实际差别较大,但其显示的动态变化与实际结果基本一致,二者的发生变化率无显著性差异;(5)本系统采用的诱捕计数数据管理系统应用方便快捷,使梨小食心虫成虫的监测数据得以有效查询与管理,并且二次开发简单高效。
[Abstract]:Pear borer is an important pest in forest and fruit production. In order to control it scientifically, it is necessary to be timely and accurate in the prediction and forecast. Accurate estimation of the number of insects is the basis of forecasting. However, at present, the trapping and statistical work of Pear minnow is time-consuming and laborious, and the work of monitoring and forecasting is prone to lag behind. In order to reduce the difficulty of the investigation and improve the efficiency and accuracy of the investigation, the local plant protection departments lack a mature and effective forecasting system for the prediction and prediction of Pear minnow. In this study, the target insects were collected by a trap with a sex trap and an automatic counting system. Based on the prediction characteristics of the related models, we established a real-time and fast data reporting system for small adult pear insects. And complete the automatic collection, statistics, inquiry and forecasting functions of the adults of Pear small heart-eating insects. In order to improve the efficiency and level of its forecasting. Finally, the preliminary prediction value of the occurrence period of local pear borer was calculated from the monitoring data of Baoding-Taoyuan pear counting system at the same time. The main conclusions are as follows: water basin type and bucket type. The trapping effect of the trap was better than that of the blue armyworm plate and the self-made water bottle trap. The four kinds of traps were sequentially entrapped to 1 293, 949, 489 and 153, respectively.) the basin trap and the bucket trap can not only be used as indicators of the dynamics of pear. Moreover, it can reduce the damage degree of pear to orchard. (3) the occurrence rule: in 2014, the peak of pear damage in 2014 was in late June and middle and late July in Baoding Mancheng Tuonan area. In late August, there was a certain error between the statistical results of the trap automatic counting system and the actual survey results, and the difference between the individual survey data and the actual results was quite large due to the abnormal server and rain weather. However, the dynamic change of the system is basically consistent with the actual results. There is no significant difference in the rate of change between the two systems. 5) the trapping and counting data management system used in this system is convenient and fast. So that the monitoring data of adults of Pear fruit-eating insects can be queried and managed effectively, and the secondary development is simple and efficient.
