| ABSTRACT Hermetism, a behavior that isolates ant colonies, was studied in the laboratory between two ant species in Chile, Camponotus morosus Smith and Linepithema humile Mayr. Ants from five nests of C. morosus and L. humile were used, transferring ten individuals per nest of one of the colonies to receiving nests of the other. Conducts, including antennal exploration (AE), mandible opening (MO), dorsal flexion of the abdomen (DFA), biting (Bi), ventral flexion of the abdomen (VFA), fight (Fi), transport of the intruder ant (TI), moving backwards (MB), and death (De) were recorded during ten min, with ten replicates. The times of occurrence ± SD of each event were analyzed with the Student t test. The events AE, MO, DFA, and MB had a short latency time in... |

| Se comparó la susceptibilidad larvaria de la polilla del tomate, Tuta absoluta (Meyrick), colectada en tomate (Lycopersicon esculentun Mill.) en Azapa, Arica (18º 31 lat. Sur, 70º 11 long. Oeste), mediante pruebas de toxicología con varias dosis de insecticidas de uso común, aplicados sobre grupos de larvas de dos niveles de desarrollo (estadíos 1-2 y 3-4). Para determinar la resistencia a los insecticidas se calcularon las DL50, DL90 y pendientes de las regresiones entre mortalidad (probit) y dosis (log). Se verificó la resistencia a los insecticidas estudiados, pues las DL50 al menos duplicaron aquellas en Ovalle y Quillota, localidades donde T. absoluta presentó la mayor resistencia en otro estudio. Deltametrina y mevinfos fueron los compuestos menos... |

| The effects of four insecticides (dimethoate, pirimicarb, imidacloprid, and spinosad) applied in an ST4 Potter tower at sublethal concentrations (50% of those recommended commercially for aphid control) were studied in the laboratory on aphidiid Aphidius ervi (Haliday) adults, an important parasitoid of the pea aphid Acyrthosiphon pisum (Harris). The most selective treatment on the hymenopteran was imidacloprid, followed in decreasing order by spinosad, pirimicarb, and finally dimethoate, which quickly eliminated the parasitoid and thus its capacity to produce progeny. Three toxicity groups were distinguished in the study. The least damaging treatment to adults of A. ervi was imidacloprid, followed by a group of medium toxicity made up of spinosad and... |
