The number of hosting plants for the Carambola fruit fly (Bactrocera carambolae) in Brazil has jumped to 21, with over four species infested in the state of Amapá (the only one with occurrence in the country).
This was pointed out in a study by the Brazilian Agricultural Research Company (Embrapa), conducted in support with the National Program of Eradication of the Carambola Fruit Fly, in coordination with the Ministry of Agriculture, Livestock, and Supply.
This time, tangerine, guava-araçá or araçá, cashew, and orange were added to the list. In relation to the latter, this is the first time that infestation by the Carambola Fruit Fly in South America has been reported.
According to Embrapa researchers, the knowledge of potential hosting plants of the Carambola fruit fly is crucial for the biological safety and zoo-phytosanitary defense of the Brazilian agricultural production because it gives subsidies to the establishment and allows success in actions of control.
Considering the major phytosanitary barrier for Brazilian fruit exports, due to the imposed barriers by importing countries, the Carambola fruit fly originated in Southeast Asia. According to Mapa, if the plague escapes control, it can generate a potential loss of US$ 30.7 million in the initial year and nearly $92.4 million in the third year of infestation in Brazil.
At present, the 21 vegetable hosting species are: Cashew, Mango, Taperebá, Biribá, Ajuru, Licania sp., Acerola, Muruci, Araçá-boi, Pitanga, Guava, Guava-araçá, Plum-purple, Jambo-red, Carambola, Sapotil (sapoti), Abiu, Cutiti, Mandarin, Ground Orange and Black Pepper.
