A Detailed Guide to the Latest Control Methods for Wheat Aphids
Wheat aphids are one of the main pests of wheat, commonly known as oil insects, greasy insects, honey insects, etc. They pierce and suck the sap of wheat, affecting wheat photosynthesis as well as nutrient absorption and translocation. After wheat heads out, they gather on the spikes to cause damage, forming shriveled grains, reducing the thousand-grain weight and causing

How to control wheat aphids? Three measures to improve control effectiveness
Wheat aphids are one of the main pests currently harming wheat. In recent years, due to changes in climatic conditions, a decrease in the number of natural enemies, and improper control measures in wheat fields, the harm caused by wheat aphids has become increasingly serious, resulting in reduced wheat yield and declining quality. In response to farmers' situations in controlling wheat aphids, taking the following three measures can improve the control effectiveness of wheat aphids. Determine whether to control based on the control threshold. The control threshold for wheat aphids is 500 aphids per 100 ears. As long as a field reaches the control threshold, pesticide control should be applied immediately. Controlling according to the control threshold not

How to control wheat aphids more scientifically? A detailed guide to practical methods

Although wheat aphids occur and cause damage year after year, farmers still have some misunderstandings in their control. How can wheat aphids be controlled more scientifically? It is recommended to pay attention to the following three points: 1. The appropriate time to start control. In general years, the appropriate time to start controlling wheat aphids (when the number of aphids per 100 plants rises to 500) is after wheat flowering (before grain filling), generally around May 5. Starting control at this time is best. As long as the right pesticide is used and the dosage meets the requirements, generally one control treatment can solve

Chinese scientists discover that the dominant wheat aphid species is changing due to climate change
Recently, a team led by researcher Ma Chunsen of the Institute of Plant Protection, Chinese Academy of Agricultural Sciences, after 6 years of research, found that climate change has broken the original balance of agricultural pest communities, changed the relative dominance among species in pest communities, and caused succession of the dominant species. It can
