Effect of actinomycin-D on the fat body RNA content in Dysdercus koenigii (Heteroptera: Pyrrhocoridae)

The effect of actinomycin-D on the RNA content of the total fat body was studied on day 3, 4, 5 and 6 of the first reproductive cycle in the females. Actinomycin-D exhibited its highest inhibitory effect in insects injected on day 4 and a lower degree of the effect was seen in insects injected on da...

Summary:The effect of actinomycin-D on the RNA content of the total fat body was studied on day 3, 4, 5 and 6 of the first reproductive cycle in the females. Actinomycin-D exhibited its highest inhibitory effect in insects injected on day 4 and a lower degree of the effect was seen in insects injected on day 5. These results suggest that by the end of day 4, a major quantity of DNA-dependent RNA, necessary for vitellogenin synthesis, has already been synthesised and accumulated.
