Studies on arthropods associated with tropical rainforest canopies contribute to a further understanding of forest canopy community dynamics and their relationship to the structure and function of this ecosystem. This study evaluated arthropod community composition in monodominant Callisthene fasciculata forest canopy throughout the high water and dry periods in the northern region of the Pantanal in Mato Grosso, Brazil, as a part of a project about arboreal canopy arthropods associated with monodominant areas in this region. Sampling was conducted on 12 individuals of C. fasciculata, six from the high-water season (2010) and six from the dry season (2011), using insecticide fogging. A total of 28,197 arthropods were collected. Hymenoptera (the majority being Formicidae), Diptera, Acari, Thysanoptera, Hemiptera and Coleoptera, were the most representative groups. Although the analysis did not show variation in the abundance of individuals between the high water and dry seasons, the arthropod community varied significantly in taxa composition. Opiliones, Embioptera, Ephemeroptera and Scorpiones occurred only during the high-water period, with Polyxenida and Strepsiptera occurring only in the dry season. Thysanoptera was more abundant in the dry season, showing a relationship with the beginning of the C. fasciculata flowering period. In general, the high water and dry seasons maintain distinct communities in this habitat, illustrating how the temporal variation in the phenology of C. fasciculata imposed by the Pantanal’s hydrological regime alters the composition of the associated arthropod communities in the canopy of these monodominant formations in the Pantanal of Mato Grosso.

Desde el 2009 se ha evidenciado en las plantaciones de cacao del valle de Zarumilla (Tumbes, Perú), la presencia de un insecto plaga de especie aún no identificada, cuyas larvas perforan los tallos y frutos del cacao, y afectan su valor comercial por la invasión de microorganismos patógenos secundarios. Este trabajo de investigación que se realizó de marzo a agosto del 2014 tuvo como objetivos identificar y describir morfológicamente al barrenador del fruto y tallo del cacao, no reportado para las condiciones de este valle. Las recolectas se realizaron en campos cacaoteros del valle de Zarumilla y la crianza de los estados inmaduros, en el laboratorio de Entomología de la Universidad Nacional de Tumbes. Los resultados permitieron determinar que la especie cuya larva perfora los tallos y frutos del cacao es Carmenta theobromae. Se describen las principales características morfológicas de esta especie, referente a los estados de huevo, larva, pupa y adulto de ambos sexos. Además, del material biológico recolectado en campo durante el muestreo, se identificaron dos parasitoides a nivel de familia, un díptero Tachinidae recuperado de larvas y un himenóptero Chalcididae a partir de pupas. Se concluye que la especie que barrena los frutos de cacao en las plantaciones del valle de Zarumilla es C. theobromae. El presente estudio servirá de base para realizar futuras investigaciones de la biología y comportamiento en relación con los factores ambientales y determinar si esta especie tiene preferencia por determinados clones de cacao sembrados en la zona.

The macromorphology of Beauveria bassiana (B1), Metarhizium anisopliae (M1) and Isaria javanica (HPI-210) strains was studied, as well as its radial growth at temperatures of 25, 28, 30, 35 and 40 °C in PDA medium supplemented with powder of Diatraea considerata, Spodoptera frugiperda and Galleria mellonella. The fungi were inoculated by adding 2 µl of a suspension with 1 x 107 spores/ml. Afterwards the radial strains growth in mm/d was measured during 15 d. To determine the interaction between the three strains, the three lepidopteran powders, control PDA and the five temperatures, a factorial analysis 3 x 4 x 5 was used; fungi growth data was analyzed by ANOVA and Tukey test. The macromorphological characteristics of each species were studied, finding significant statistical differences in the growth at different temperatures, with respect to the control. The optimal growth for the three fungi was at 28 °C. Strain B1 supplemented with D. considerata powder grew 2.76 ± 0.06 mm/d, M1, G. mellonella 2.77 ± 0.02 mm/d and M1 HPI-210 D. considerata 3.27 ± 0.06 mm/d. Strains B1 grew 0.45 ± 0.03 mm/d and M1 1.22 ± 0.03 at 30 °C, while HPI-210 did not grow after 28 °C. These results suggested that the strains were induced by medium contained insect supplementation; at 28 °C, HPI-210 obtained the best growth/d (F = 25.24, E8, P = 0.0001), followed by M1 and B1, while M1 supplemented with S. frugiperda grew best at 30 °C (F = 38.33, E8, P = 0.0001). These results of radial growth, macromorphology and tolerance of strains at temperature, allow the selection of the best strains to assess its virulence in insect pests.

Caryocar brasiliense (Malpighiales: Caryocaraceae) trees, protected by Brazilian federal laws, are the main income source in many communities. The transformation of the Cerrado (savanna biome) into grazing or agricultural areas has been isolating these trees species in an agro-urban landscape. We studied the effects of environmental diversity on the abundance of galling insect communities inhabiting C. brasiliense trees in three different environments: Cerrado, pasture, and an urban area. Eurytoma sp. (Hymenoptera: Eurytomidae) adults and their galls, its parasitoid Sycophila sp. (Hymenoptera: Eurytomidae) and the predator Zelus armillatus (Hemiptera: Reduviidae) were present in larger numbers on the C. brasiliense leaflets in the urban area. The percentages of totally galled leaflets (exhibiting all kinds of galls) and the number of trees were negatively correlated. Greater habitat diversity favored that of galling insect species and their natural enemies.

Chrysoperla externa is a widely distributed and highly adaptable predatory insect. In order to evaluate its capacity as a natural enemy of the sugarcane aphid, Melanaphis sacchari, its life table when reared on M. sacchari was inferred. The biological cycle lasted an average of 29.5 ± 6.2 d from egg to adult. The embryonic and larval period duration was 5.1 ± 0.3 and 13.8 ± 4.5 d, respectively. The pupa stage was completed in 10.6 ± 1.4 d, whereas adults lived 63.5 ± 26.7 d after eclosion. The mortality rate showed the highest values in the egg stage (qx = 0.17). The greatest survival rate appeared in the third instar (93.7 %). The period prior to reproduction was 6.5 ± 3.1 d. The average fecundity was 228.3 ± 139.1 eggs. The life table parameters were Ro = 113.2, T = 28.9, rm = 0.163 and λ = 1.17. According to the results, it is possible to infer that C. externa is capable of accomplishing its life cycle feeding only on M. sacchari.

Acute pesticide poisoning is a global public health problem. In developing countries pesticides cause up to one million cases of poisoning and up to 20,000 deaths annually. In Mexico, it has been reported that due to intoxications by xenobiotics, among them pesticides, 1,400 people die annually. In the present work a method was optimized to detect and quantify malathion in third instar fly larvae (Diptera) that hatched in pork meat, Sus scrofa domesticus, treated with the lethal dose in humans of malathion (60 g/60 kg). A biomass of 1.5 g which was added 1.2 mL of phase, stirred by space 5 min and centrifuged for 10 min at 10.000 rpm. The supernatant was analyzed by HPLC, using a methanol-water phase (70/30). The retention time of malathion was 4.1 min. The detection limit was calculated at 0.301 ppm. The technique and procedure used will serve as an indirect tool to identify the presence of the toxin in a relatively simple way in court cases.

La achira o sagú (Canna indica) es una planta originaria de la cordillera de los Andes y cultivada en Colombia para la obtención de almidón a partir de sus rizomas. El almidón es utilizado en su mayoría como materia prima en la fabricación de bizcochos y otros productos autóctonos de consumo local y regional. Sin embargo, los productores de achira han mostrado reciente preocupación por la aparición de plagas que pueden ser limitantes en la productividad. El objetivo de este estudio consistió en reconocer los principales insectos asociados al cultivo. Se visitaron zonas productoras en los departamentos de Cundinamarca, Huila y Nariño. Se identificaron varios insectos nocivos del orden Lepidoptera en su estado larval, como Glyphipterix sp. (Glyphipterigidae), Spodoptera sp. (Noctuidae), Calpodes ethlius y Cobalus cannae (Hesperiidae), y el chinche Ischnodemus sp. (Hemiptera: Blissidae). También, entre otros insectos benéficos, se observó la emergencia de adultos de una avispa parasitoide de la familia Ichneumonidae a partir de larvas del microlepidóptero Glyphipterix sp., y se identificaron dos enemigos naturales de la chinche Ischnodemus sp., una avispa parasitoide de huevos (Hymenoptera: Chalcidoidea) y el hongo entomopatógeno Beauveria bassiana. Esta información puede servir como base de próximos estudios sobre aspectos de la biología y hábitos de los principales insectos nocivos de edible canna (Canna indica), así como de potenciales agentes de control biológico con el fin de generar recomendaciones de manejo en el cultivo de la achira.

Gladiolus is a cut flower with the highest year-round demand in Mexico, generating strong economic and social activity. Thrips are the pest that most affects gladiolus and require the most control, but which species cause damage are still unknown. This study aimed to characterize the diversity of thrip species associated with gladiolus cultivation in two production regions of Mexico State. Two plots were established: one in Ixtlahuaca, in the northern part of the state, characterized by less intensive management, and one in Villa Guerrero, in the southeastern part of the state, characterized by intensive management and considered the main production region for ornamentals. Thrips were captured from 100 floral spikes per plot at the end of the cultivation cycle. Results showed the presence of two genera and five species of phytophagous thrips, as well as one predatory thrip genus, in the northern region, while in the southeast region the same two genera were represented but with 12 species, one of which is new for Mexico. Thrips simplex was the most abundant species in both plots evaluated.

The aim of this work is to describe and illustrate new teratological cases in species of the genus Phyllophaga. A total of 830 specimens collected in 2013 and 2017 in Sierra Sur region of the state of Oaxaca, Mexico were reviewed. Two cases of morphological anomalies were found. The first case is a clypeal malformation in Phyllophaga dasypoda, and the second case is a bifurcated right antenna with double antennal club in Phyllophaga misteca.
