Therefore, reduced transpiration would lead to less absorption of the active ingredient by the roots, thus less active ingredient would be translocated throughout the plant, resulting in less control or regulation of citrus mealybug populations. They cause damage by sucking the juice from their host plants. Second, citrus mealybugs may be less susceptible to systemic insecticides than aphids and whiteflies, which could be affiliated with their feeding behavior that is different in the number and length of time of intracellular punctures and stylet mobility during the phloem-searching process. Less toxic alternatives such as insecticidal soap or horticultural oils can be effective, but must be applied to the hard-to-reach places the mealybugs inhabit to kill the insects.

Treating with neem oil will kill mealybugs on contact at any stage of the life cycle—without harming any beneficial bugs, such as honeybees, that are also in the area. In conclusion, feeding behavior may impact the effectiveness of systemic insecticides in regulating populations of the citrus mealybug. Therefore, we conducted a number of experiments to assess the effectiveness of systemic insecticides against the citrus mealybug and to also quantify the feeding location (plant stem, leaf top and leaf bottom) on coleus (Solenstemon scutellarioides) plants. A homemade spray of rubbing alcohol and dish soap, however, solves that problem. Neem oil is another safe insecticide that can be directly to active infestations. £7.95. Step 3.

Mealybug populations are difficult to mitigate with insecticides because they spend some or all of their life cycle in inaccessible areas on plants such as leaf junctures and on the underside of leaves, which may be extremely difficult to reach with sprays of contact insecticides especially when plants have complex plant architectures (many branches and leaves) (Figure 2).

For the experiments with neonicotinoid insecticides imidacloprid, dinotefuran and thiamethoxam, citrus mealybug mortality was highest 21 and 28 days after treatment for all three systemic insecticides with thiamethoxam and dinotefuran providing the highest mortality (more than 60 percent); however, mortality declined substantially 35, 42 and 49 days after treatment (Figure 5).
