Inhalt:

The objective of the study was to increase rice production by screening three (03) NERICA (New Rice for Africa) rice varieties against African rice midge (Orseolia oryzivora) attack and to integrate efficient biological control in rainfed rice cultivation.During the rice cropping cycle, each phenological stage of the plant is sampled every two weeks using the D-VAC aspirator and mowing net throughout the cropping season, as this sampling frequency corresponds to a specific phenological stage. White hearts were sampled during the bolting stage of the plant. NERICA 3 is more susceptible than the other two varieties because it has a higher AfRGM population. The abundance of the AfRGM population varies according to the collection method (Sweep-Net and D-VAC). Collection using the D-VAC was more efficient than Sweep-Net.Only 5 live AfRGM individuals were recovered out of 38 observed.
