The live will be broadcast on 26/06, from 18h to 20h, on embrapa Youtube channel
Continuing the series of online debates on topics of agricultural development in the Amazon, Embrapa Amapá and Embrapa Roraima will hold next Friday, 26/06, from 18h to 20h (Brasilia time) to live "Quarentenian pests in the context of the Brazilian Amazon", with broadcast on embrapa channel on Youtube (www.youtube.com/embrapa)
Researcher Ricardo Adaime, from embrapa Amapá's Agricultural Entomology area, and analyst Rinaldo Joaquim da Silva Júnior, who works with Integrated Pest Management at Embrapa Roraima, will discuss the issue with the Coordinator of Plant Protection, Ministry of Agriculture, Livestock and Supply (Mapa), Graciane Gonçalves Magalhães de Castro. The debate will be conducted by the Secretary of Agriculture, Livestock and Supply of Roraima, Emerson Carlos Baú. The audience will be able to send questions and comments through the broadcast interaction chat.
During the live, will be discussed research results and challenges for the permanent fight against quarantine pests, as well as socioeconomic and environmental impacts for production systems throughout Brazil. In the Amazon, there are several quarantine pests present, with relevant research developed by Embrapa, including absent pests. The debate on this subject becomes even more necessary due to the borders of the Brazilian Amazon with other countries, such as Bolivia, Colombia, Peru, Venezuela, Guyana, Suriname and the Department of French Guiana, where the transit of biological materials such as plants and fruits occurs between countries.
What is the difference between Present and Absent Quarantine Pests?
Quarantine pests include a long list of insects, mites, fungi, bacteria, viruses, nematodes and weeds, with the potential to cause social, economic and environmental damage to Brazil's agriculture and also put the population's food security at risk. The researcher Ricardo Adaime explains that Prague Quarentenária Ausente (PQA) is the pest of potential economic importance for an area in danger, which is not present in the national territory. While Prague Quarentenária Presente (PQP) is a pest of potential economic importance for an area in danger, present in the country, but not widely distributed and that is under official control, such as the carambola fly that currently has restricted circulation to the states of Amapá, Roraima and Pará.
According to analyst Rinaldo Joaquim da Silva Júnior, the emergence and establishment of pests cause negative socioeconomic and environmental impacts on production systems throughout Brazil. "Currently, Roraima is the state with the highest number of quarantine pests present and the one with the highest probability of new pests arriving due to the large dry border we have with the Federative Republic of Guyana and Venezuela. This probability increases even due to the transit of biological materials (plants and fruits) with refugees and immigrants who cross the country illegally," he said.
Fruit fly and red palm mite
In recent years, Embrapa has been investing in research to give greater relevance to the theme. The "I Symposium of Quarantine Pests in the Brazilian Amazon" was promoted in Roraima in 2015, which served as the basis for the formulation of the "Quarantine Pest Arrangement", now incorporated into the "Plant Health Portfolio". In addition, some projects under Embrapa were carried out to specifically study quarantine pests, such as the formation of the Plant Health Network (2002-2006); Amazon Research Network on Fruit Flies (2007-2010 and 2011-2015); Carambola fly in Brazil: biology, ecology and control (2014-2018); e Introduction of the exotic lysitoid Fopius arisanus (Hymenoptera: Braconidae) in Brazil with a view to the biological control of the carambola fly, the last three led by Embrapa Amapá.
Within embrapa roraima, studies developed in the last 12 years stand out, such as the project Biological control of insects by Trichogramma (Hymenoptera, Trichogrammatidae) in agroecosystems and forest systems in the state of Roraima (2008); in addition to research with the red mite of palm trees and its threat to Brazil as a plague of quarentenarian expression, ranging from preparations for biological control, bioecology, hosts and control; in addition to the development of an Integrated ácaro_vermelho_das_palmeiras Management Package for small producers in Dominica (Caribbean) and Brazil in 2014, and the occurrence of the Citrus Hindustanic Mite (Schizotetranychus hindustanicus).
Prevention of absent quarantine pests
With regard to the prevention of missing quarantine pests, the prioritization effort is recorded through a work carried out by 64 technicians, most of them from the Ministry of Agriculture, Livestock and Supply, and Embrapa, published as an e-book in the following link: http://ainfo.cnptia.embrapa.br/digital/bitstream/item/196767/1/Livro-PragasPriorizadas-1ed-2018-Ainfo-ver-final-1.pdf
STAY ON TOP OF IT
Quarentenary pests present of greater importance in the Brazilian Amazon, and their agricultural crops and production systems most affected:
|Species||Agricultural Crops||Production Systems|
|Hose, guava, jambeiro, caramboleira, aceroleira, etc.||Fruit growing|
|Various palmaceous||Fruit growing and ornamental plants|
|Maconellicoccus hirsutus* (pink cochineal)||Several||Several|
|Schizotetranychus hindustanicus (citrus mite)||Citrus||Fruit|
|Pseudocercospora fijiensis (black sigatoka)||Banana and Heliconia spp.||Fruit growing and ornamental plants|
*Today they are not on the list of 400-year-old Pests Present.
