小麦在5月份时就进入抽穗期-灌浆期，也同样进入了红蜘蛛的侵害期。小麦红蜘蛛是一种对农作物侵害很大的昆虫，如何做好防治工作，农业人需要重视的。那么红蜘蛛发生的规律是什么？又如何防治呢？

小麦红蜘蛛的发生规律

①麦蜘蛛也同样是螨虫，主要通过吸收小麦汁液危害小麦。被红蜘蛛危害的小麦，首先从下部叶片开始受害，随后逐渐向中、上部分蔓延。受害叶片会出现黄白色斑点，并随虫害加重，逐渐出现红色斑点，并出现叶片局部卷缩的现象。被危害的小麦，植株发育不良、矮小，甚至导致全株枯萎，随之产量减少，乃至绝产。

②小麦红蜘蛛分两种，一种是麦长腿蜘蛛，一种是麦圆 spiders. 麦长腿 spider喜温暖喜干旱，最适宜的温湿度为气温18°左右, 湿度50%以下；而麥圓 spider则与之相反, 喜阴暗潮湿，最适宜发生温湿度为气温12°, 湿度80%以上。

Small-maize red spider's preventive measures

Control water supply and artificial control of the red spider.

Keep field hygiene by timely weeding and use appropriate herbicides to eliminate weeds that harbor insect pests.

Implement crop rotation with stubble retention and strengthen field management.

Ensure adequate base fertilization combined with rational application of phosphorus and potassium fertilizers to enhance the resistance of wheat plants.

The recommended pesticide for killing red spiders is avermectin, which has a good effect, easy to use, stable in nature, and has dual effects of contact poisoning and stomach poisoning, benefiting in controlling red spiders.

By following these guidelines for preventing small-maize red spider damage can ensure safe planting of grains crops like wheat.

This article will provide you with an overview on how small maize (wheat) is affected by the Red Spider pest during its growth cycle as well as offer tips on how to prevent this problem from happening in your fields so that you can grow healthy crops without any negative impact from pests like the Red Spider.

Red Spiders are known for causing significant damage to cereal crops such as wheat due to their feeding habits where they suck plant sap leading eventually into reduced crop yields or even total loss if not properly managed. The key here is early detection followed up by prompt action using integrated pest management techniques including biological controls along chemical treatments when necessary but always ensuring safety standards are met at all times while managing these pests effectively within agricultural settings especially those involving cereals like maize (wheat).

To make sure your farm stays protected against harmful insects it's crucial you stay updated about current best practices when dealing with specific pest threats such as Red Spiders affecting your maize (wheat). This includes learning more about their life cycles patterns behaviors etc., being proactive through preventative measures mentioned above; knowing what tools chemicals pesticides work best suited towards each species' unique needs & vulnerabilities - this knowledge allows farmers manage risks effectively reducing losses caused by unwanted visitors inside farms most importantly maintain food security levels globally!
