“…The mealybug citrus lodges in the roots during the dry season of the year and with the beginning of the rains and irrigations to induce flowering they rise to the aerial part of the coffee tree, attacking the flowers, pellets and the base of the fruits (Fornazier et al, 2018;Fornazier et al, 2019;Santa-Cecília et al, 2007). In addition, a downward migration of citrus mealybug has been reported in conditions of low air temperatures, with a predominance of nymphs in the coffee root system at temperatures close to 15 ºC, while with the temperature rise at levels close to 30 ºC, insects demonstrate a predominance of infestation in the upper part of the plants (Santa-Cecília et al, 2011). Similarly, in citrus crops in the Arizona-USA region, citrus mealybugs such as P. citri hibernate in the upper roots, trunks and lower branches of the tree, where they lay eggs that hatch in April and infest the reproductive parts (Kerns;Wright;Loghry, 2001).…”
