Fundecitrus researchers Marcelo Miranda and Wellington Ivo Eduardo participated in the recent XXIX Brazilian Congress of Entomology in Uberlândia in the state of Minas Gerais.
In a round table discussion on fruit plant pests, Miranda addressed the challenges of implementing integrated pest management in citrus for insect vectors of pathogens. This includes the leafhopper that transmits citrus variegated chlorosis and the psyllid that spreads citrus greening disease.
“Research shows that, when measures are used appropriately, it is possible to achieve more efficient and sustainable management,” Miranda said. “Carrying out correct monitoring using insecticides with adequate rotation and other control tactics, such as processed kaolin and mineral oil, are measures that help in the fight against it. New studies are underway to improve citrus pest management.”
Eduardo discussed the effect of mineral oil concentrations on the Asian citrus psyllid (Diaphorina citri), which spreads citrus greening.
“Studies carried out in the laboratory evaluated the concentrations of mineral oil to control the different life stages of the psyllid,” Eduardo said. “The results showed that topical application of mineral oil does not kill psyllid eggs, but concentrations of 0.5% and 1% control nymphs and adults.”
The main theme of the event was sustainability and biodiversity of insects. Researchers, teachers, agribusiness professionals, consultants, producers and undergraduate and postgraduate students participated in the Brazilian Congress of Entomology.
Fundecitrus is an association maintained by citrus growers and juice manufacturers from the state of São Paulo to foster the sustainable development of the citrus industry.
