Abstract: gynaikothrips ficorum (marchal) is a pest of the laurel tree in urban zones and insecticides are possibly used for its control, but its initial response to these products is unknown. therefore susceptibility of various populations of this species was determined (texcoco, córdoba and tlayacapan) to the insecticides permethrin, cypermethrin, diazinón, malathion, methyl oxydemeton, methyl parathion, endosulfán and methomyl. the texcoco population was used as reference to make comparisons of the response. at 24 h of exposure, the confidence levels of the cl50 of the three populations overlapped in the insecticides cypermethrin, diazinón, malathion and methyl oxydemeton; but they did not overlap in córdoba and tlayacapan with texcoco, for permethrin, methyl parathion, endosulfán and methomyl. for córdoba and tlayacapan with cypermethrin, the resistance proportion (rp50) was 0.88 and 0.53'; with diazinón, 0.3 and 0.29'; with malathion 1.04 and 1.02'; with methyl oxydemoton 0.74 and 7.18'; with methyl parathion 8.4 and 4.63'; with endosulfán 1.19 and 0.2', and with methomyl 0.11 and 0.53'. at 95 % mortality, only in tlayacapan and for endosulfán (rp95=0.03), the fiducial limits did not overlap with the other two populations. the values obtained at 48 h of exposure followed the same tendencies found at 24 h. these response values correspond to a susceptible state and can be used as comparison reference.

Diversidad, fluctuación poblacional y plantas huésped de escolitinos (Coleoptera: Curculionidae) asociados con el agroecosistema cacao en Tabasco, México Diversity, dynamic population and host plants of bark and ambrosia beetles (Coleoptera: Curculionidae) associated to the cocoa agroecosystem in Tabasco, Mexico

Abstract: Se estudió la diversidad de escolitinos asociados con el agroecosistema cacao en Tabasco, México durante el a o 2007. Los insectos adultos fueron recolectados en 4 localidades con trampas de alcohol etílico, trampas de atracción luminosa y captura directa sobre sus plantas huésped. Se recolectaron 19 263 ejemplares, pertenecientes a 51 especies y 26 géneros. Araptus hymenaeae y Cnesinus squamosus son nuevos registros para México. La máxima diversidad de insectos capturados con los 3 métodos de recolecta se obtuvo en El Bajío (H'=2.45 y Dmg=4.83), la mínima en Río Seco (H'=2.29) y Km. 21 (Dmg=3.85), y el máximo valor de equidad (J) lo obtuvo El Bajío (0.67). El índice de similitud de Sorensen (Is) mostró que los sitios de estudio tienden a presentar la misma composición de especies. Los índices de diversidad, equidad y similitud, aplicados a la fauna de escolitinos capturados con cada uno de los métodos empleados, mostraron diferencias, excepto en las trampas de alcohol. La fluctuación presenta picos poblacionales marcados al inicio y al final del a o de estudio. Las plantas en las que se recolectó el mayor número de especies fueron Theobroma cacao (16) y Swietenia macrophylla (13). The bark and ambrosia beetle diversity in cocoa agroecosystems was studied during 2007 in Tabasco, Mexico. Adult insects were gathered in 4 localities with ethanol and light traps and by direct collecting in their host plants. 19 263 specimens were gathered, belonging to 51 species and 26 genera. Araptus hymenaeae and Cnesinus squamosus are new records for Mexico. The maximum diversity of insects captured with the 3 collecting methods was obtained in El Bajío (H'=2.45 and Dmg=4.83), the minimum in Río Seco (H'=2.29) and Km. 21 (Dmg=3.85), and the maximum value of justness (J) was obtained in El Bajío (0.67). The Sorensen similarity index (Is) showed that the study places present the same species composition. The diversity, justness and similarity indices, applied to the beetles captured with each method, showed differences except with the alcohol traps. The beetles present marked populational picks at the beginning and at the end of the year. The biggest number of Scolytinae species were gathered in the host Theobroma cocoa (16 species) and Swietenia macrophylla (13).

Abstract: the male and female genitaliae of three species of the genus heilipus germar (h. lauri boheman, h. pittieri barber and h. trifasciatus fabricius) that damage avocado fruits (persea americana mill.) in mexico and costa rica are described and illustrated. the aedeagus, spiculum gastrale, styli of 8th sternite are different in each one of the three species studied and can be used for specific identification.

Neotropical Entomology , 2009, DOI: 10.1590/S1519-566X2009000500007
Abstract: the scolytidae fauna associated to the cacao agroecosystem in tabasco, mexico was studied during 2007. adult insects were captured by using ethanol and light traps, and by direct collecting in their host plants. 3,192 specimens of 34 species belonging to 18 genera of scolytidae were collected. twenty-two species are new records for the state of tabasco. the genera with more species were xyleborus (6) and hypothenemus (6). we conclude that the scolytidae fauna associated to the cacao agroecosystem captured with the three trap systems are similar through the year of study. we also conclude that although the ethanol traps were more efficient, obtaining the highest species diversity, the use of other methods is important.

Abstract: from august 1997 to august 1998, 334 specimens of triatoma longipennis and 62 of t. picturata were collected in four groups of localities placed in the zone from guadalajara, jalisco to tepic, nayarit, in the west coast of mexico. most t. longipennis were collected outdoors (69.2%) while most t. picturata (58.1%) were collected indoors. all collected specimens were examined for trypanosoma cruzi infection, which was detected on 98 (29.3%) t. longipennis and 17 (27.4%) t. picturata. this study confirms the role of t. longipennis and t. picturata as some of the main t. cruzi vectors to humans in mexico. habitation infestation rate with t. longipennis was of 0.09 and with t. picturata was of 0.03 and the predominating ecotopes were pile of blocks, chicken coops, pigsties, wall crawls and beds.
