After day 10, developmental progress was again markedly slower, and on day 12 the average stage of this treatment group was significantly behind that of the control group (P < ). Larvae fed on Anemia en- riched with the highest dose of MF showed significantly slower development to advanced stages than the control group, starting on day 5 (P < ); this effect lasted till the end of the experiment, and only a small progres- sion of larval stages was recorded from that day onward. Effect of metlivl farnesoate on metamorphosis Metamorphosis—which takes place after the 11th lar- val stage—was delayed in a dose-dependent manner in larvae treated with MF, but survival was similar to that in the control. In summary, the three experiments showed that among the surviving control individuals, 28 (58%) reached the postlarval stage at the end of the experiment. In the low MF concentration 20 (31%) normal post-larvae were found, and as higher MF concentrations were used, significantly fewer post-larvae were found—only 8 (14%) and 5 (8%), respectively.
