They produce a sticky substance that attracts ants and promotes the growth of sooty mold. To manage mealybugs, prune the heavily infested parts and apply insecticidal soap or horticultural oil according to the instructions on the label.
2. Scale insects: Scale insects are small, immobile insects that attach themselves to the plant's stems, leaves, and fruits, sucking out the sap and subsequently causing yellowing, leaf drop, and twig dieback. To manage scale insects, prune heavily infested parts and apply horticultural oil or insecticidal soap according to instructions on the label.
3. Caterpillars: Caterpillars are the larvae of butterflies and moths that feed on the plant's leaves and fruits, causing defoliation and fruit damage. To manage caterpillars, handpick them and destroy them. Applying Bacillus thuringiensis (Bt) according to instructions on the label can also be an effective management option.
In conclusion, the management of diseases and pests in Boscia suaveolens Gilg & Gilg-Ben. involves good cultural practices and the use of chemical control methods.
