Table 2 Egg-laying and larval survival of A. obtectus on artificial seeds incorporated with bean seed coat powder

From: How the seed coat affects the mother’s oviposition preference and larval performance in the bean beetle (Acanthoscelides obtectus, Coleoptera: Chrysomelidae, Bruchinae) in leguminous species

Artificial seed treatment1 Number of eggs laid/female (mean ± SE) Dead L1 outside (%) Dead larvae inside (%) Adults emerged (%)
2.5% seed coat 8.6 ± 2.1a 14.3 85.7 0
5.0% seed coat 4.5 ± 1.6a 28.9 71.1 0
10.0% seed coat 6.6 ± 1.2a 12.9 87.1 0
Control 7.6 ± 2.3a 2.7 2.7 94.6
  1. 1Artificial seeds (balls) consisted of 80% cotyledon powder plus 20% water-soluble potato starch powder. A portion of the latter was substituted with 2.5–10% seed coat powder. Control balls contained only cotyledon and starch powders. The Brown-Forsythe test indicated homogeneity of variances of the number of eggs laid/female: F3,48 = 1.5344, p = 0.2176, and one-way ANOVA (F3,48 = 0.8445, p = 0.4763), as-well-as the Scheffé post-hoc test were not significant at p < 0.05 (means signed with the same small letters)
