ASIPUELA-HARO, René; GALARZA, Wilson; RAMIREZ, Herman  and  MARTINEZ RIVERO, María de los Ángeles. Hosts of Lincus curvatus Campos & Roell and Macropygium reticulare Fabricius and plant reservoirs of Phytomonas sp. in the O×G oil palm plantation. Rev. Protección Veg.

Plant hosts of Lincus curvatus Campos & Roell and Macropygium reticulare Fabricius and carriers of Phytomonas sp. surrounding the oil palm were studied in the states of Tripomastigote and Amastigote in the province of Orellana, Ecuador. It was set up a multifactorial split plot design with two blocks (High mortality-2.5 % and Low mortality-0.01 %), three plots (Inter palm lines, bordering area and jungle), and three sub-plots, in which the number of insects hosted per unit of plant species was evaluated. Twenty eight plant species classified within eighteen families were identified. L. curvatus was found in: Fabaceae, Marantaceae, Arecaceae, Heliconiaceae, Cyclanthaceae, Asteraceae, and Musaceae; M. reticulare was found in: Urticaceae, Asteraceae, Araceae, Commelinaceae, Arecaceae, Musaceae, Poaceae and Fabaceae. The families reservoirs of Phytomonas sp. in the stated of Tripomastigote were: Euphorbiaceae and Arecaceae, while in the state of Amastigote were; Musaceae, Araceae, Alismataceae, Poaceae, Euphorbiaceae, Heliconiaceae, and Marantaceae. The highest population of L. curvatus was found in the jungle plot, while M. reticulare was found in the inter palm line plot
