The numbers of male and female wheat midges from each trap were recorded. A 5% interspersed refuge produces wheat midge larvae which damage seeds. In addition, amino acid residues did not differ between the ivy fruit gall midge and the soybean pod gall midge. The matings of midges in the separate blocks would be strongly assortative for virulence against crop resistance genes. Chapter 5 is perhaps the focus of the book - the author's own research on pollination, largely by midges. The wheat midge and its parasitoid oviposited throughout the plots, and parasitism was density independent. Occasionally, however, they will take long-continued flights, when the course is more or less direct and distinctly midge-like. Inside some skins of dead, parasitized midge larvae, fully-fed parasitoid wasp larvae could be observed. Applying this technology, raspberry cane midge damage and the consequent disease problems could be controlled more adequately. The remaining galls were not dissected but kept in plastic containers (10 cm in diameter, 6 cm in depth) to rear adult midges. Without this deterrence, the ratio of production of midges would have been 14:1 instead of 41:1 in susceptible versus resistant wheat. This resistant wheat also deterred midge oviposition, reducing egg densities by 65% compared with susceptible wheat. The proportions of midge-affected seeds in harvested wheat were estimated at 10-15 magnification. Three haplotypes (haplotype 1, 2 and 3) were found in the sequential variations of the soybean pod gall midge (table 7). These examples are from corpora and from sources on the web.
