Defining Effects of Insect Test Report Lamps on Prevention and Control Indicators
2019-07-17 09:02:29
The determination of the indicators for the detection and control of the insect report light should be adjusted according to the weather, rice growth period and growth conditions. The growth and development of rice leaf roller require moderate temperature and high humidity. It is generally considered that the suitable temperature is 22 to 28°C and the relative humidity is 80% or more. Due to different weather conditions during the year, there are large fluctuations in the mating rate, egg production, hatching rate of eggs, and survival rate of newly hatched larvae. For example, if the weather is rainy, the damage will be aggravated. From tight, in case of high temperature and drought, the prevention and control indicators can be appropriately relaxed.
When determining the specific prevention and treatment time, based on the occurrence period of the moth derived from the reference insect report lamp, we must focus on the investigation of the amount of eggs in the field, and pay attention to the development of the eggs, and investigate once, if necessary, 2 to 3 days. It is more reliable to control the time for eggs. The developmental progress method and period distance method can be used to predict the beginning and end of the moths of the next generation adult moth, and the peak period of the moths.

Impact of insect report lamp on climatic conditions in the growth and development of rice leaf roller . The growth and development of rice leaf roller requires moderate temperature and high humidity. It is generally considered that the suitable temperature is 22 to 28°C and the relative humidity is 80% or more. Adults have temperatures above 29°C and relative humidity below 80%. The hatching rate of larvae is also affected. The occurrence of rice leaffolders has not been substantially affected, and the field still shows the phenomenon of “more moths, more eggs, and more insectsâ€. This remains to be further studied in the future.
The detection of the insect report light indicates that the same insect amount is different for different rice growing stages. During the tillering stage, rice grows vigorously and its compensation ability is strong. If the yield loss of the flag leaf is large during the spike stage, the later rice leaves become hard, and the young larvae are difficult to roll leaves, and the damage is lighter. Therefore, when the control index is determined, the tillering period is broad. From the booting to the full heading period, the width is wide after full heading. In addition, some of the prevention and control indicators for small fields, excessive use of nitrogen fertilizer, green leaf color, and late-maturing late-maturing crops should be tight.
