Himenópteros parasitoides associados a ninfas de Triozoida limbata na cultura da goiabeira, em Ivinhema, MS, Brasil

Abstract

RESUMO O Brasil tem excelentes condições climáticas para a exploração comercial da goiabeira Psidium guajava L. (Myrtaceae); porém, em todo o país, a cultura é atacada por insetos-praga, sendo Triozoida limbata Enderlein, 1918

Electrostatic spraying in the chemical control of Triozoida limbata (Enderlein) (Hemiptera: Triozidae) in guava trees (Psidium guajava L.)

“…However, the expansion of this crop and changes in production systems have provided conditions conducive to the emergence of phytosanitary problems. The guava psyllid, Triozoida limbata (Enderlein, 1918) (Hemiptera: Triozidae), is the main pest in this crop . These sap‐sucking insects are between 2 and 2.4 mm in length as adults, and their highest population densities occur from September to November.…”

Psyllaephagus trioziphagus (Hymenoptera: Encyrtidae), parasitoide de Mastigimas anjosi (Hemiptera: Calophyidae)

“…This parasitoid has occurrence records in Brazil (states of Mato Grosso do Sul, Rio Grande do Sul, Santa Catarina and São Paulo), Canada, Costa Rica, Cuba, the USA, Jamaica, Mexico, Panama and Peru. Noyes & Hanson (1996) (Melo, 2009;Sá & Fernandes, 2015).…”
