Record of Trichogramma marandobai Brun, Moraes & Soares, 1986 (Hymenoptera: Trichogrammatidae) in cassava crops in the Federal District, Brazil

Year: 2026

Type: article

Abstract: This note reports the first record of the egg parasitoids Trichogramma marandobai Brun, Moraes & Soares, 1986 and Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) in cassava (Manihot esculenta Crantz) crops in the Federal District, Brazil. Sampling was conducted in an experimental field at Embrapa Cerrados from August 2023 to July 2024, and male specimens were identified based on genital morphology. Trichogramma marandobai was recorded between March and April 2024, extending its known geographic distribution in Central-West Brazil. Trichogramma pretiosum is also reported for the first time in cassava crops in this region. These records expand current knowledge of egg parasitoid diversity associated with Erinnyis ello (L., 1758) (Lepidoptera: Sphingidae), support updates to the Taxonomic Catalog of the Brazilian Fauna (TCBF), and provide baseline information for the development of biological control strategies in cassava agroecosystems.
