Traditionally, brown soft scale has been controlled by the use of pesticides, but these have the disadvantage that other insects, friends and foes alike, are also killed. Another approach in citrus is to eliminate ants from the trees, either by preventing the ants from climbing the trunks or by destroying their nests.
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no ...

Another research study conducted in the field found a positive correlation between the presence of ants on host plants and the success of green scale insects. On coffee trees from which ants had been excluded the number of scale insects had declined after fifty days and after seventy days, none remained, whereas scales had thrived on ant ...

Pseudaulacaspis pentagona, the white peach scale [1] or mulberry scale, is a species of armoured scale insect in the family Diaspididae. [2] This scale infests over 100 different genera of plants including many fruit trees and ornamentals.
The scale insects excrete honeydew on which bees, wasps, ants and other insects feed. Sooty mould fungus often grows on the honeydew and this decreases the area of leaf available for photosynthesis, spoils the appearance of the plant and reduces the marketability of fruit. [4] It is especially damaging to young trees after transplanting. [5]
