As the foliage dies back the mites wander along it and so cross to adjacent bulbs.
The aphid produces large quantities of honeydew which cover the foliage and provide an ideal substrate for the growth of sooty moulds.
In an agricultural field it is usually easy to take recordings above the foliage canopy.
Biochemical aspects and significance of rapidly induced changes in birch foliage.
Given these facts, we believed our treatments would expose nymphs to foliage of significantly different quality.
In order to capture a sufficient number of seeds to follow temporal patterns, we avoided setting traps and quadrats under dense palm foliage.
We examined 100 terminals of foliage per block at two intervals during the season for aphids, and sampled leafhopper adults on sticky traps.
Throughout the experiment, larvae always received foliage from the same trees.
