abstract = "Adzuki bean beetle (Collosobruchus chinensis L.) is one of the devastating storage pests of field pea (Pisum sativum L.) crop that serves as a stable food in Ethiopia. In direct increments of insect pest due to an application of organic and in organic fertilizers for yield increment also another challenge. This study was focuses on resistance potential of field pea genotypes across location and different fertility levels. The reaction of 35 field pea genotypes were evaluated with no choice condition to C. chinensis infestation in the laboratory with RCBD with three replications 2017/18 growing season. The  combined ANOVA over the two locations  showed significant difference at (P0.01 and P0.05) for most characters regardless of the soil fertility levels, genotypes except for thousand seed weight and proportion of seed coat weight (Tables 3). Traits like; number egg, date of adult emergency, number of adult emerged, adult recovery, mean number of hole per seed, susceptibility index and thousand seed weight, proportion of seed coat, percentage of seed weight loss showed highly significant (p  0.01) differences due to  the application of  fertility levels (table 5).  The regressions among seed weight loss (%) and considered field pea genotypes based on fertility levels were showed similar distribution even if it was vary in magnitude. Interrelations between the traits revealed strong associations in a number of cases both in positive and negative directions across location and fertility levels. Nearly all traits were responsive to the location difference (table 5) because of daily temperature variation. Genotypes with better seed size revealed shortest media development; while the longest media developments were recorded for small seeded one. This insect had the capacity to infest and develop on all field pea genotypes tested, however with significant differences among locations and fertility levels that stemmed the existence of moderately resistance field pea genotypes those can be used with other integrated pest management practices in breeding system.",
