Descrição: A long-term survey of Lygus populations was carried out on 8 field crops in southern Finland. Weekly samples were taken with a sweep net throughout the growing season in 16 successive years. The dominant species on all crops was L. rugulipennis Poppius, constituting 92% of the total number of adults. L. gemellatus (Herrich-Schaeffer), L. pratensis (L.), L. punctatus (Zetterstedt), and L. wagneri Remane occurred in small numbers. Bugs were most abundant on wheat. Development of the nymphs was highly dependent on the temperature in June. The total numbers varied considerably from year to year and were generally highest after warm preceding summers and dry autumns and springs. Multiregressional models were developed to forecast numbers of Lygus bugs
