| Se realizaron experimentos para determinar la preferencia de color de trips (Frankliniella occidentalis Pergande) en cultivos de pimiento (Capsicum annum L.), en las localidades de Cerrillos de Tamaya (30° lat. S.; 71°16 long. O) y Pan de Azúcar (29°55 lat. S; 71°14 long, O) de la IV Región de Chile. En diseño de bloques completos al azar, se compararon trampas de pegamento azul, blanco, blanco-azul y amarillo.Los resultados mostraron que F. occidentalis fue la especie predominante en el cultivo de pimiento. En la trampa de color azul, blanco-azul y blanco se capturaron significativamente más trips que en las trampas amarillas, cuando las capturas fueron superiores a 300 trips semanales por trampa. Los resultados fueron erráticos con capturas inferiores. |

| Thrips of the genus Frankliniella cause significant reduction on grape production. Little is known about its decision making approach in integrated pest management and information on thrips injuries to the vine is scarce, hindering the control of this pest. This study aimed to determine the species of thrips and injuries that cause damage to berries in seedless grapes clusters. The trial was conducted in an area cultivated with Vitis vinifera L., variety Thompson Seedless, using a randomized block design with five treatments and four replications. The treatments consisted of artificial infestation (zero, two, four and eight thrips per inflorescence), and treatment determined by the monitoring system of the grower. Each replication consisted of three plants... |

| The thrips, Frankliniella schultzei, and green peach aphid, Myzus persicae, cause direct damage to plants of economic importance and transmit phytoviruses, causing large economic losses. Chemical constituents of essential oils present a wide range of biological activities. The aim of this work was to evaluate insecticidal activity of essential oil from citronella grass, Cymbopogon winterianus, on F. schultzei and M. persicae. This essential oil was obtained by steam distillation and components were identified by GC/FID and GC/MS. A Potter spray tower was used to spray insects with the essential oil. The major constituents are geraniol (28.62%), citronellal (23.62%) and citronellol (17.10%). Essential oil of C. winterianus at 1% (w v-1) causes mortality in... |
