In this study, we determined the microbiota composition of M. opercularis at the larval (caterpillars) and adult (moths) stages by next-generation sequencing. DNA was extracted from the caterpillars and moths, and the 16S rRNA prokaryote gene was then amplified and sequenced with next-generation sequencing to assess bacterial richness. Comparison of the microbiota of the caterpillars and adults revealed variation in species composition and diversity. The microbiota of the caterpillars of M. opercularis was composed of 259 species, dominated by the families Geodermatophilaceae (12%), Propionibacteriaceae (10.41%), Clostridiaceae (9.63%), and Nitriliruptoraceae (7.72%). In the adult moths, we found 138 species, and the most abundant families were Nostocaceae (24%) and Methylobacteriaceae (21%). Species richness in M. opercularis was higher in the caterpillars compared to adults. We determined that only some groups of bacteria could persist from 1 stage to another.

Therefore, its detection in avocado-growing regions of Mexico that had been designated pest-free can halt national and international trade. One option for monitoring S. catenifer is the use of synthetic sex pheromone traps. In this study we determined the optimal density of pheromone-baited traps for monitoring S. catenifer. The experiment was conducted in 4 commercial Hass avocado orchards in Colima, Mexico, each with different pest infestation levels. Trap densities were established at 0.5, 1, 2, or 3 traps per ha. The traps were checked every 15 d and the number of moths recorded. The density of 3 traps per ha captured the most moths per trap followed by 1 trap per ha; similar small numbers of moths were captured at densities of 0.5 and 2 traps per ha. In general, there was a linear relationship between trap catch and trap density per ha. The overall default error rate, i.e., the proportion of traps did not detect moths when they were present, was 5.5% at a density of 3 traps per ha and 2.7% at trap densities of 0.5 and 2 traps per ha. Furthermore, at a density of 1 trap per ha all traps captured moths and so there was no default error. Since S. catenifer is a quarantine pest that must be detected promptly to reduce the risk of dispersal and establishment in moth-free areas, it is suggested that a density of 1 trap per ha should be used in avocado orchards to effectively monitor for the presence of this pest. However, this estimate was obtained through the bootstrapping technique, which involves the creation of pseudoreplicate datasets by resampling. Randomized field experiments with true replicates are needed to corroborate this result. Resumen La presencia de Stenoma catenifer Walsingham, una plaga cuarentenaria, puede cancelar la comercialización nacional e internacional de aguacate Hass de zonas libres de plagas reglamentadas del aguacatero. Una opción para su oportuna detección es el uso de trampas con feromona sexual sintética. El objetivo del estudio fue determinar la densidad de estas de trampas para el monitoreo de S. catenifer. El experimento se estableció en cuatro huertos comerciales de aguacate Hass, con diferentes niveles de infestación de la plaga, en Colima, México. En los huertos, se establecieron las densidades siguientes: 0.5, 1, 2, y 3 trampas por ha. Las trampas se revisaron cada 15 días para registrar el número de palomillas capturadas. La densidad de 3 trampas por ha capturó el mayor número de palomillas, seguida de la densidad de 1 trampa por ha, mientras que las capturas con 0.5 y 2 trampas por ha fueron las menores, pero muy similares entre sí.

In agroecosystems, adults disperse between habitats, foraging on crop and non-crop hosts, oftentimes vectoring a harmful plant pathogen, Xylella fastidiosa Wells et al. (Xanthomonadales: Xanthomonadaceae). Understanding the spatiotemporal dynamics of this species in crops and the surrounding non-crop habitat may lead to improved pest management programs that reduce pathogen transmission. Here, we used 3 yr of trapping data across a southeastern US agroecosystem to characterize spatiotemporal distribution patterns of the glassy-winged sharpshooter in a variety of habitats. Adult glassy-winged sharpshooters were captured weekly on yellow sticky cylinder traps. Spatial Analysis by Distance Indices (SADIE) was used to identify significant aggregations and interpolated maps generated to characterize distribution patterns of adults within season and between yrs. Overall, the distribution of glassy-winged sharpshooters varied seasonally with individuals captured primarily in woodlands and fallow fields during early season mo. Later in the growing season and as population levels increased, sharpshooters were captured more commonly in crop habitat, including wheat and corn fields. By evaluating spatiotemporal distribution patterns, we identified likely sources of spring migration into cropping systems. Thus, pest management strategies for the glassy-winged sharpshooter should seek to limit early spring migration from non-crop habitat into crop fields.

When beetle eggs at the base of the plant or on the soil and beetle larvae on the foliage were offered to the predator on bok choy plants (Brassica rapa L.; Brassicaceae), C. rufilabris larvae killed 5.3 times more beetle larvae than eggs, likely due to prey location. Killed eggs were located on the base of the plant; no eggs placed on the soil, close to the base of the plant, were killed or damaged. In the simple environment of a Petri dish, the predator showed a 5.2-fold preference for aphids over M. ochroloma eggs and larvae presented separately. When 3 prey options were presented, first instar C. rufilabris killed 4.8 times more M. persicae nymphs than beetle eggs and 3.8 times more nymphs than beetle larvae. The killing rate of M. ochroloma eggs and larvae by C. rufilabris decreased about 73% when M. persicae nymphs were present. When only eggs and larvae of M. ochroloma were offered in Petri dishes, the predator did not exhibit any prey preference.
