During the inter cropping period were sampled fruits infested with the CBB from 31 coffee plantations in four municipalities. The infested fruits were dissected in order to detect the presence of any of the three species of CBB parasitoids: Cephalonomia stephanoderis, Prorops nasuta and Phymastichus cofea. We were also looking for parasitism by the native parasitoid Cephalonomia hyalinipennis. For analysis, we considered several variables, such as parasitoid earlier releases, species of coffee planted, altitude of sites, the prior existence of rural young, presence of rivers and conditions of coffee (careful or careless). Tis data was analysed in a Generalized Lineal Model. The results showed that C. stephanoderis was found in 67,7% of samples, and the percent of parasitism ranged from 0,33 to 26%. C. hyalinipennis was only detected in a single sample and its parasitism was 3%. P nasuta and P. cofea were not found in the samples. The presence of C. stephanoderis was correlated with altitude, the species of coffee and the number of previous releases, among others. In this study we confrm the establishment of C. stephanoderis, 20 years after its first release in coffee plantations of Chiapas, Mexico.10aHypothenemus hampei1 aRuiz, Jaime, Gomez1 aOvilla, Andoni, Santos1 aValle-Mora, Javier1 aGerardo, Pablo, J.

The trial was conducted in a coffee plantation located at the Jaime Henao Jaramillo Experimental Field Station, Faculty of Agronomy, Universidad Central de Venezuela, Miranda State (average temperature: 19.9 [degree]C, average RH 83.8 %, average rainfall: 1 321.5 mm/year) during July-October/2004. The treatments (height) were replicated five times and distributed in a randomized block design. In each block, baited traps were placed at a distance of four meters between them on the same ground level curve, for eight periods of seven days. At the end of each period, traps were checked to remove the traps capture, refill them and change randomly their position. At the laboratory, the capture was identified and separated by orders and H. hampei. The catch values obtained for each height tested were expressed in terms of Borer/Trap/ Week (BTS) and the statistic analysis allowed to detect significant differences (p >= 0.05) between treatments, resulting the heights 0.5, 1.0 and 1.5 m of similar efficiency to capture H. hampei.10aHypothenemus hampei1 aDel Pozo, Javier1 aGonzalez, Eutimio1 aCasares, Rafael1 aCastillo, Ana1 aMeneses, Hecni  uhttps://weevil.myspecies.info/height-placement-intercept-traps-and-its-effects-captures-hypothenemus-hampei-ferrari02223nas a2200241   4500008004100000020001400041245014900055210006900204260000900273300001200282490000700294520127000301653002301571100003101594700003301625700002401658700003001682700002901712700003401741700003701775700003401812856013501846       2009                        eng d  a1317-526200aInfestation index and mortality factors of the cotton boll weavil weevil (Coleoptera: Curculionidae) in the semi-arid southeast of Bahia, Brazil0 aInfestation index and mortality factors of the cotton boll weavi  c2009  a111-1220 v243 aThe boll weevil (Anthonomus grandis Boheman, 1843) (Coleoptera: Curculionidae) is a pest that limits the production of cotton, especially in the North East of Brazil. The present study aimed to estimate the infestation index and natural mortality of boll weevil at Caraibas County, located in the semi-arid of the Southwest of Bahia. Te experiment was performed using the cultivar BSR Aroeira, at Fazenda Lagoa Seca, in 2006. Weekly evaluations were performed, in fve sampling areas 25m2, collecting blossoms fallen on the ground. The infestation was estimated by counting the oviposition punctures and /or the feeding on blossoms, and also by the presence of one of the phases of the boll weevil in the inside. Mortality factors were studied through the dissection of blossoms, estimating predation, parasitism, dissection and disease. The results obtained allowed to conclude that the boll weevil determines high infestation levels in the region. Parasitism, dissection and predation, following this order, determine high rates of real mortality of the pest. Catolaccus grandis Burks, 1954 (Hymenoptera: Pteromalidae) and Bracon sp.(Hymenoptera: Braconidae) are parasitoids of boll weevil reported in sothwestern Bahia, being the frst one the predominant species.10aAnthonomus grandis1 aCardoso, Urbano, Pinchemel1 aCastellani, Maria, Aparecida1 aForti, Luiz, Carlos1 aJunior, Ayres, de Oliveir1 aMoreira, Aldenise, Alves1 aColmenarez, Yelitza, Coromoto1 ade Oliveira, Marcelo, Eduardo Co1 aBittencourt, Maria, Aparecida  uhttps://weevil.myspecies.info/infestation-index-and-mortality-factors-cotton-boll-weavil-weevil-coleoptera-curculionidae-semi-arid
