Estudos Biológicos De Cochonilhas Do Gênero Planococcus (Hemiptera: Pseudococcidae) Em Diferentes Hospedeiros

Abstract: RESUMO Este trabalho teve por objetivo estudar o desenvolvimento de populações de cochonilhas do gênero Planococcusem diferentes espécies vegetais, visando à verificação de especificidade hospedeira. A cochonilha Planococcus minorfoi obtida de plantas de cacau (Theobroma cacaoL.) e de café (Coffea canephoraPierre), enquanto Planococcus citrifoi obtida de plantas de citros (Citrus sinensisL. Osbeck). Ovos foram transferidos individualmente para placas de Petri contendo discos foliares de cacau (T. cacaocultivar… Show more

“…However, during the reproductive phase of conilon coffee, these insects had a preference for coffee plants, demonstrating the susceptibility of the crop to the pest at this stage. Such observations corroborate the results obtained by Correa et al [14]. These authors, when studying the biology of scale insects of the genus Planococcus in different tree hosts, observed that the species P. citri and P. minor have a greater food preference for coffee plants.…”

“…Ten third instar nymphs of each mealybug species, were taken from the rearing and fasted for one hour. Soon after, the insects were released in the middle placed on the circle of filter paper (Correa;Santa-Cecília, 2008;Oliveira, 2013). So, both mealybugs species were allowed to choose between Conilon 213 and Mundo Novo leaves.…”

“…In C. arabica, several researches on the development and reproduction of these insects were carried out in Brazil (Correa et al, 2011;Santa-Cecília et al, 2009;Oliveira, 2013;Sousa et al, 2012;Costa et al, 2016). Different periods of development and reproduction of both mealybug species in these coffee plants are found in these literature but laboratory results are difficult to compare due to different experimental conditions, manipulation and above all, the host plant and the plant organ used.…”
