| Abstract: | This paper is a study on the economical control index of Englishgrain aphids. Based on the results obtained and the allowable damagerate of 5%, we consider that it is reasonable to control their damage bychemical methods once during the period from late flowering stage to earlymilky ripe stage. The index is follows: 300 aphids per 100 spikes of wheatat the output level of 250 kg per mu; 250 aphids per 100 spikes of wheatat the output level of 300 kg per mu; 200 aphids per 100 spikes of wheatat the output level over 350 kg per mu. |
