AbstractMetopolophium dirhodum (Walker), a grain aphid, contained 25.58% dry matter, of which 31.65% was fat, 2.58% sugar, and 39.44% protein. Foliage of the host for M. dirhodum, oats (Avena sativa L.), contained one-third the amount of dry matter, less than one-third as much fat, slightly less sugar, and about three-fifths the amount of protein as M. dirhodum. Phosphorus content was the same in M. dirhodum and its host, whereas oat foliage contained five times as much potassium, and twice as much calcium and magnesium as M. dirhodum. The limiting amino acid in both grain aphid and oat foliage was methionine. Protein scores, which are estimates of protein quality, were slightly lower for oat foliage than for M. dirhodum but both are valuable sources of food for predatory insects and other animals.

SummaryIntroduction:Rose grain aphid (Metopolophium dirhodumWalk.) is one of the most important pests on cereals in Poland. The economic importance of this pest has increased in recent years due to the increase in the area of maize cultivation.M. dirhodumis an oligophagic aphid feeding also on different rose species.Objective:The purpose of the present study was to evaluate the dynamics of population ofM. dirhodumon the saltspray rose.Methods:The studies were conducted on saltspray rose stands at Aleksandria Park in Siedlce in 2005–2009. At each selected stand, 50 rose shoots were observed every 7 days from March to spring migration of the aphid.Results:First fundatrices of theM. dirhodumon theR. rugosawere observed at the end of March. The rose-grain aphid population development on the primary host during May, and reached maximum population in the middle of May. During autumn, the aphid backed for overwintering on the primary host.Conclusion:While theM. dirhodumpopulation outbreaks, the aphid might be a serious pest of the saltspray rose.

AbstractMetopolophium dirhodum (Walker) is occasionally a pest of cereals in the UK. A simulation model was developed to study its population dynamics and damage potential. The model was initiated by the aphid immigration as measured by 12·2-m suction trap samples and with temperature as the major driving variable. It was validated with field observations from three contrasting years, 1979, 1985 and 1986. The model accurately predicted aphid populations and yield loss in a major outbreak year (1979) but was less accurate when densities were lower (1985 & 1986). Possible reasons for these discrepancies are discussed.
