Figure 3. Limnocoris submontandoni testis with clomazone 162 in Ecotoxicological effects of commercial herbicides on the reproductive system of aquatic arthropod Limnocoris submontandoni (Hemiptera: Naucoridae)
Figure 3. Limnocoris submontandoni testis with clomazone 162 mg / L, (A) Apparent enlargement of the testicular interstice and degeneration of some spermatoids (SPTI), with normal concentrations of spermatozoa (SPTZ) in the outer regions, (B) spermatocytes (SPTO) with normal appearance and sperm (SPTZ) with slight alteration of spermatids (SPTI), C) profusion of sperm (SPTZ) with a high degree of compaction, indicating high rates of spermatogenesis and integrity of tubular cells (arrowhead). Dye: Toluidine Blue.
