Effect of liquid nutrients on the development and reproduction of the predacious mite, Amblyseius gossipi.
MetadataShow full item record
The facultative predacious mite, Amblyseius gossipi El-Badry was able to develop, survive and reproduce on molasses, royal jelly and yeast hydrolysate diets. Compared with a palm tree pollen grain diet, the maximum number of individuals attaining maturity was on royal jelly or a combination of royal jelly and molasses. The duration of the development time, from larva to adult, was twice as long as that on pollen grains. The maximum reproduction/female/day was recorded on royal jelly and molasses or their combination and the minimum on yeast hydrolysate. Individuals neither developed nor reproduced on clean plant leaves.
