Background <p>The use of pesticides as contaminants is well documented. Non-target life might be severely hurt. One of these lives is locust embryos that spend their life in egg pods just beneath the soil surface.</p> Results <p>In the present work, authors described the embryonic development of the Egyptian locust <i>Anacridium aegyptium</i> as well as some effects of a low dose of a nerve poison abamectin. Here, the authors used the percent development (%D) to describe the rate of development and to make comparison with previously studied insect’s embryos. Development as fertilization, zygote formation, early cleavage, blastoderm, gastrula, inner layer, membranes, and organongy were described. Abamectin was applied topically to eggs and the LC₅₀ recorded was 31.641 ppm. The main organs that were affected were the brain and the compound eyes as well as little effects on the cuticle and the pleuropodia. The brain was smaller than usual, the optic lobe shrinkage and malformed. The compound eyes and optic nerves were abnormal.</p> Conclusions <p>Locust and grasshoppers’ embryos can be used as an example of subterranean life that might be affected by pollutants such as pesticides. Malformation during embryogenesis especially the brain and compound eyes, might document this assumption.</p>
