Control of green peach Aphid Myzus persicae (Sulzer, 1776) (Hemiptera: Aphididae) on Brassica plants


Diabaté Dohouonan, Tano Yao

The green peach aphid Myzus persicae (Sulzer) is an economically important pest of crucifer. We evaluated the efficacy of aqueous extracts of powder of grains and leaves neem Azadirachta indica (A. Juss) and a powder of jatropha curcas (Jatropha curcas L.) on the number of Myzus persicae (Sulzer) (P = 0.001) and on the cabbage yield (P = 0.001) in open field. All aqueous extracts of neem and of jatropha, and the insecticide Cypercal 50 EC (50 g / L of cypermethrin) have the same efficacy against Myzus persicae. Furthermore, only the aqueous extracts of neem grain powders 41.5 g / L increased yield (73 T/ha) compared to Cypercal 50 EC (45.5 T/ha). The aqueous extracts of neem leaf 67 g/ L (47.5 T/ha) had a similar efficacy to Cypercal 50 EC (45.5 T/ha). In addition, the aqueous extracts of jatropha grain powders 59.1 g/L gave a lower yield (39.25 T/ha) than that of the insecticide Cypercal (45.5 T/ha). Thus, aqueous extracts of neem grain powders 41.5 and neem leaf pulp 67 g/L can replace the insecticide Cypercal against Myzus persicae in cabbage farm.
