Resumo: | The mealybug Pseudococcus longispinus (Targioni Tozzetti, 1867) (Hemiptera: Pseudococcidae) has been reported attacking coffee crops and causing fruit fall in the State of Minas Gerais, Brazil. The knowledge of its biology is necessary to implement control measures. Its development was studied at temperatures of 15, 20, 25, 30 and 35ºC. The insects were confined inside a Petri dish containing a foliar disc of 4 cm diameter of Coffea arabica L., cultivar 'Acaiá Cerrado'. The temperature affected the P. longispinus development and survival. Few insects reached the final stage at temperatures of 15 and 30°C, and 100% of mortality was obtained at 35ºC. The duration of the nymphal stage was reduced when the temperature was risen from 20 to 25ºC, with a survival rate of 80% on both temperatures. The thermal requirements varied according to the development stage of the mealybug. The base temperature was fixed at 8.0 ºC for the nymphal stage of females and a thermal constant of 422.1 day degrees. The number of generations increased with the temperature. The optimal temperature for the insect development was 25ºC. |

O entendimento da dinâmica populacional dessa praga faz-se necessário para adoção de medidas de controle. Assim, estudou-se o desenvolvimento desse inseto nas temperaturas constantes de 15, 20, 25, 30 e 35ºC e determinou-se as suas exigências térmicas. Os insetos foram mantidos em placas de Petri contendo discos foliares de 4 cm de diâmetro de Coffea arabica L. cultivar Acaiá Cerrado. Constatou-se que a temperatura influenciou o desenvolvimento e sobrevivência de P. longispinus em cafeeiro, sendo registrado um baixo número de cochonilhas nas temperaturas de 15 e 30ºC e uma total mortalidade a 35ºC. A duração da fase ninfal foi inversamente proporcional quando se elevou a temperatura de 20 para 25ºC, sendo observado 80% de sobrevivência em ambas condições. Os parâmetros térmicos variaram de acordo com a fase de desenvolvimento de P. longispinus, sendo registrado o limiar térmico inferior de 8,0ºC para o desenvolvimento da fase ninfal de fêmeas, uma constante térmica de 422,1 GD e número de gerações crescente com a elevação da temperatura. A temperatura mais favorável ao desenvolvimento do inseto foi a de 25ºC.Editora UFLA2011-09-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/135Coffee Science - ISSN 1984-3909; Vol. 6 No. 2 (2011); 91-97Coffee Science; Vol. 6 Núm. 2 (2011); 91-97Coffee Science; v. 6 n. 2 (2011); 91-971984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporenghttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/135/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/135/pdf_1Copyright (c) 2012 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessSanta-Cecília, Lenira Viana CostaPrado, ErnestoSousa, Marcella Viana deSousa, Ana Luiza Viana deCorrea, Lilian Roberta Batista2013-02-24T12:38:07Zoai:coffeescience.ufla.br:article/135Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:31.856881Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |
