Última Susceptibilidad de Frankliniella occidentalis (Thysanoptera: Thripidae) a Insecticidas en la Zona Central de Chile Agricultura Técnica Vargas M,Robinson; Ubillo,Alejandrina. La susceptibilidad del trips de California, Frankliniella occidentalis (Pergande) a formetanato (Dicarzol 500 SP), metamidofos (Tamaron 600 SL), dimetoato (Perfekthion) y spinosad (Success 48) fue evaluada utilizando concentraciones seriadas asperjadas con la Torre de Potter, sobre hojas de frejol. En los bioensayos fueron utilizadas hembras adultas provenientes de tres localidades de la V Región (Ocoa 32º55’ lat. Sur, 71º05’ long. Oeste; 365 m.s.n.m.; Auco 32º52’ lat. Sur; 70º40’ long. Oeste; 762 m.s.n.m., y Vichiculén 32º52’ lat. Sur; 70º57’ long Oeste; 279 m.s.n.m.). Los resultados fueron sometidos a análisis de Probit y fue calculado el factor de resistencia (FR) obtenido de las...

Agric. Res. Navea O,Dennis; Vargas M,Robinson. Latania scale, Hemiberlesia lataniae (Signoret), has become a major pest of avocado (Persea americana Mill.) in Chile and has reached high populations in the fruit because of limited natural control. The objective of this study was to identify the biological parameters of the parasitoid Aphytis diaspidis (Howard) as a control agent of latania scale. Postembryonic development, parasitoidism rate, and life table parameters of the parasitoid and scale were determined under laboratory conditions. Aphytis diaspidis postembryonic development and parasitoidism rate varied significantly when evaluated on distinct latania scale stages with the highest survival (56%) occurring at the third scale stage, it also had the shortest development time between egg and adult...

Agric. Res. Rioja S,Tommy; Vargas M,Robinson. The avocado red mite Oligonychus yothersi (McGregor) is the major leaf pest in Chile’s avocado orchards. Itaffects leaf physiology and makes it necessary to seek new natural enemies to interact with low population densities of O. yothersi. The potentiality of three predator mites: Cydnodromus picanus Ragusa, Amblyseius graminis Chant, and Galendromus occidentalis (Nesbitt) was evaluated under laboratory conditions (27 ± 1.93ºC, 87 ± 3.61% H.R. and 16:8 (L:D) photoperiod) on avocado leaf disks Persea americana Mill. var. Hass (Ø = 5 cm) by separately feeding eggs, immature, and adult females of O. yothersi, and registering postembryonic development, consumption, as well as life table parameters. The postembryonic development of C. picanus was significantly... Tipo: Journal article Palavras-chave: Postembryonic development; Predation; Pollen; Biological control.
