METHOD FOR LONG-TERM LIMITATION OF HAZARD OF PHYTOPHAGE FLIES

摘要

A method for long-term limitation of hazard of phytophage flies includes technique of settling laboratory cultures of entomophages onto plants. In autumn under-winter ploughing is carried out for a depth not less than . In addition seedlings of vegetables are planted into unprotected area 10-12 days prior to the beginning of egg laying of females of cabbage root fly and other flies. In 10-12 days after planting of the seedlings double foliar fertilizing of the plants is carried out with an interval of 14-16 days, with an aqueous solution of the organic fertilizer Riverm in an equivalent of 5 and of the fertilizer per . In the period of the beginning of egg laying of females of the flies double settling of the predator insect Aleochara (Aleochara bilineata Gyll.) is carried out with an interval of 10-11 days. In doing so a settling rate is 180-200 imagoes per and settling is carried out on not less than 20 points on area of .
