Traps craft with attractive alcoholics in the control of the coffee berry borer, Hypothenemus hampei (Ferrari 1867) in Cologne Bolinda, Caranavi
Abstract
The coffee is one of the main cultivated crops in the Caranavi region, among the biotic stress factors; the borer of the coffee (Hypothenemus hampei) is the one that affects significantly and negatively. In order to finding alternative practical and economic for the control of the pest, it was carried this investigation in the “Bolinda” Colony of the Caranavi Municipality La Paz-Bolivia, the trial was established under a completely random, design with two study factors, e three replications, 1.5 ha distributed at random in the coffee plantations. Three types of traps were built handmade. These were, INIA, ECOIAPAR and TRAP BORER, in combination with the attractive mixtures of alcohols methanol (M) and ethanol (E) in the proportion of 3: 1; it mixes 3: 1: 1 M-E+milled coffee, 2: 1 M-E and commercial alcohol as check. Borer/trap/attractive capture was evaluated. He she was highly significant statistical differences among them. The biggest captures female adults of Hipothenemus hampei were presented in the proportion 2: 1 of M-E and ECOIAPAR trap (T8) was identified as the most efficient and economic, being able to capture 4877 borer, with a cost trap (1.50 Bs) and the attractive (2.20 Bs), continued by the T2 with the same cost (proportion 3: 1 of M-E and INIA trap) with 159 borer and the treatments witnesT9, T5 and T1 (commercial alcohol) they obtained smaller captures with 23, 35 and 38 drills, which means that it is not effective for the control. The costs of the implementation of traps the marginal cost of 40 Bolivianos/ha. The results obtained in the study show the biggest borer captures were in December and January, the use of handmade traps constitutes an alternative for the control in the period of postharvest, a more practical and economic method, feasible for the producers.
