Abstract:

The abundance and reduction of Colorado beetle and the consumption of potato leaves were compared in conditions of chemical control and without. The last larval stage (L4) attains 6-8% of the initial number of eggs in the years with chemical control applied, and 15-31% in the years without chemical control. The consumption of potato leaves is also high in the years with chemical control which does not decrease the tuber crop. The energy consumed by the Colorado beetle larvae and energy returning into the habitat in the form of faeces is determined. The profit due to the presence of the shelterbelt is about 60 kcal/m2 during the season. The ratio of the faeces to consumption is about 50% on the average.
