Abstract

Bird cherry-oat aphid is the principal pest of spring barley in Denmark. The time of arrival in the fields is an important element in deciding whether chemical control is needed. This paper describes a regression model managed by climate variables, which incorporate the biology of the bird cherry-oat aphid on its primary host, the bird cherry (Prunus padus L.). In the period 1987-1998, three to nine spring barley fields were monitored annually for the first occurrence of bird cherry-oat aphid. Different climatic variables were analysed in relation to the time of arrival, with a view to constructing a model. The analysis showed good correlation between the date of arrival into the fields after 1 May (D), day-degrees (DD) in February (TF), DD in March (TM), DD in April (TA), precipitation in April (PA) and precipitation in May until 15th (PM) according to the following model: D = 0.61TF - 0.17TM + 0.30TA - 0.46PA + 1.85PM (r 2=0.98, P<0.001, df=51). DD were calculated with a threshold temperature of 3°C. It...

春季天气对春大麦中鸟樱蚜(Rhopalosiphum padi L.)到达时间的影响字段

鸟樱桃燕麦蚜虫是丹麦春大麦的主要害虫。到达田间的时间是决定是否需要化学防治的一个重要因素。本文描述了一个考虑鸟樱桃蚜对其主要寄主鸟樱桃(Prunus padus L.)生物学特性的气候变量管理的回归模型。1987-1998年，每年监测3 ~ 9块春大麦田首次发生鸟樱蚜。分析了不同的气候变量与到达时间的关系，以期建立一个模型。分析结果表明，5月1日后入田日期(D)、2月日度(DD)、3月日度(TM)、4月日度(TA)、4月降水量(PA)和5月至15日降水(PM)具有良好的相关性，模型为:D = 0.61TF - 0.17TM + 0.30TA - 0.46PA + 1.85PM (r 2=0.98, P<0.001, df=51)。DD在阈值温度为3℃时计算。它……
