“…ences between the mean percentage of loss per larva for the measured isoline losses, measured non-Bt lead losses, and model predictions ( Table 4). The percentage of yield loss measured in this study corresponds well with estimates in numerous other studies conducted across the United States (Deay et al 1949;Patch et al 1951;Chiang et al 1954Chiang et al , 1960Everett et al 1958;Chiang and Holdaway 1959;Kwolek and Brindley 1959;Jarvis et al 1961;Pesho et al 1964Pesho et al , 1965Guthrie et al 1975;Barry and Campbell 1978;Ghidiu et al 1979;Lynch 1980). Yield loss estimates from these studies varied from 1 to 12% but generally averaged Ϸ3.0% per borer per plant.…”

“…A review of early research to establish damageÐloss relationships indicated that yield loss per larva of second generation European corn borer was Ϸ1Ð3% (Deay et al 1949, Patch et al 1951. Additional studies found yield losses from European corn borer to be variable, probably due to regional differences (Chiang et al 1960, Everett et al 1958, Kwolek and Brindley 1959, Lynch 1980, Showers et al 1983).…”

Field studies in Pennsylvania and Maryland were conducted during 2000, 2001, and 2002 to test the applicability of published yield loss relationships developed in central Pennsylvania for European corn borer, Ostrinia nubilalis (Hübner), management in warmer, longer season corn, Zea mays L., grain production regions of the northeastern United States. Both isoline hybrids and non-Bt lead hybrids were compared against Bacillus thuringiensis (Bt) hybrids to measure effects of the pest on yield. The European corn borer economic analysis model was used to make site-specific predictions of loss per European corn borer larva for comparison with measured yield loss per larva. Although the model did not predict loss per larva at a field level, it did predict loss at a regional level. The model predicted an overall percentage of yield loss per larva of 2.69+/-0.12% over the region, which was similar to the measured yield loss per larva of 2.66+/-0.59% for isoline hybrids and 3.08+/-0.51% for lead hybrids. The model, on average, provided a good prediction of percentage of yield loss per larva within the climatic zones of 1100-1700 degree-days (DD) (base threshold 12.5 degrees C). Our results suggest that the yield loss relationship developed in Central Pennsylvania, when matched to the timing of third instar second generation European corn borer stalk tunneling is adequate for major corn grain production zones of the northeast United States.

“…He emphasised that, although the line was possibly curved for very low or very high populations of borers, it was straight for the range of populations that was of practical concern. Many other authors have calculated linear regressions of yield on pest numbers, injuries or injured plants (e.g., Bardner, Maskell & Ross, 1970;Buckley & Burkhardt, 1962;Deay et al, 1949;Gould & Graham, 1969;Kinzer & Henderson, 1968;Rautapaa, 1966Rautapaa, , 1968aRautapaa, ,6, 1969Rautapaa, , 1970Wilson et al, 1969). It is common practice to estimate the yield of unattacked crops by extrapolating the regression on yield to the point of zero infestation, but this can be seriously misleading if there is an unsuspected threshold level, or the upper part of the line is markedly curved.…”

A knowledge of the often complex relationship between insect populations and their effects on the yield-forming processes of crops is useful for assessing pest status and for devising methods of minimising the effects of infestation on yield. After a preliminary section on definition of terms, consideration is given to ways in which insects injure plants and crops, particularly annual crops. Investigations into the yield-forming processes of unattacked crops can often provide useful insights into the likely effect of insect injuries on yield. The differences between the characteristics of individuals and populations are discussed, both of insects attacking plants, and plants responding to the attacks of insects. The distribution of insects on plants and on crops and the effect that this has on damage is considered, as is the time and duration of the attack in relation to the growth cycle of the crop. The components of plant resistance to insect attack are then discussed, especially tolerance and the various ways in which plants and crops compensate for injury. The review concludes with an examination of the quantitative relationships between numbers of insects or injuries and their effects on yield. The generalised response is a sigmoid curve relating an upper and lower plateau of yield where changes in the numbers of insects or injuries have little effect. Most relationships conform to some part of this curve, though few show all its features.
