Abstract
The uncontrol using of pesticides, harmful to the environment, health, and it would have impact to non-target animal as earthworm. This study describes the effect of the Dicofol to cocoon production and viability of earthworm Pontoscolex corethrurus Fr. Mull., has been done in-July - Augustus 2016 at the zoology laboratory of Biology Department of Universitas Negeri Padang. The experiment used the Completely Randomized Design (4 treatments 6 replications). The treatments are with 0 g / l (P1), 0.002 g / L (P2), 0.004 g / L (P3), and 0.006 g / L (P4) and 0.008 g / L of Dicofol that diluted to water. The Data of production and viability of earthworm cocoons Pontoscolex corethrurus Fr. Mull collected during 30 days in alternate day. Data analyzed by ANOVA and Duncan New Multiple Range Test at p <0.05. The results Showed that the average number of cocoons production at P1 30 cocoons (the highest), 16 cocoons P2, P3 7 cocoons, and the P4 and P5 0 cocoons (the Lowest). The average percentage of cocoons viability were highest in P1, and P2 (100%); P3 (10%) and the cancel at P4 and P5 (0%). It can conclude that the pesticide Dicofol decreased the production and viability of the earthworm cocoons Pontoscolex corethrurus Fr. Mull.
