Smith (Lepidoptera: Noctuidae) females attract males for copulation, but no studies to date have investigated if conspecific females also are attracted. Here, the attraction of females of S. frugiperda to their sex pheromone in flight tunnel laboratory bioassays and field trapping is reported. Genitalia of females and males captured in the field were dissected for taxonomic identification and studied with an environmental scanning electron microscope to know the mating status of the females. In wind tunnel attraction bioassays, virgin females flew upwind and landed on the stimulus, likewise the males, whereas mated females, although they headed for the stimulus, showed fewer landings. The sex ratio of captured insects in the field was 1 female to 4 males. The presence of spermatophores allowed the separation of mated and virgin females using the genitalia; both were found in the traps throughout the sampling period. This study demonstrated that S. frugiperda females autodetect their sex pheromone, and its implications on the management strategy for these moths are discussed. Resumen Las feromonas sexuales emitidas por las hembras de Spodoptera frugiperda J. E.

Se disectaron las genitalias de las hembras y los machos capturados en el campo para su identificación taxonómica y también se estudiaron con el microscopio electrónico de barrido ambiental para conocer el estado de apareamiento de las hembras. En los bioensayos de atracción en el túnel de viento, las hembras vírgenes volaron contra el viento y se posaron en el estímulo, al igual que los machos, mientras que las hembras apareadas, aunque se dirigieron al estímulo, mostraron menos aterrizajes. En el campo, la proporción sexual de los insectos capturados fue de una hembra por cada cuatro machos.

Zarrabi","doi":"10.1653/024.105.0207","DOIUrl":"https://doi.org/10.1653/024.105.0207","url":null,"abstract":"Abstract Light-emitting diodes often are used to substitute and enhance fluorescent or incandescent light for plants that are grown in climate-controlled environments. These lights often are chosen over other light sources because of the light-emitting diodes' durability, long life, enhanced wavelength for specific plant species, lower energy costs, lower surface heat safety risk, and easier ability to incorporate into advanced climate control systems. However, previous studies have shown that characteristics of Sorghum bicolor (L.) Moench (Poaceae) are altered under light-emitting diodes. Therefore, we grew 4 cultivars of sorghum in growth chambers with either conventional or light-emitting diodes. Plants were infested with either the sugarcane aphid, Melanaphis sacchari (Zehntner) (Hemiptera: Aphididae) or were un-infested (control). Sorghum grown under light-emitting diodes was shorter and produced more leaves that were wider than those of plants grown under conventional lights. Two of the cultivars had lower photosynthetic rates and reduced stomatal conductance under light-emitting diodes. When exposed to sugarcane aphids, resistant cultivars tolerated aphid feeding with reduced damage under conventional lights but were similar to susceptible cultivars when grown under light-emitting diodes. Our results suggest that light-emitting diodes affect sorghum physiology and morphology, and also compromises resistance to herbivores. Our study provides further evidence that the physiological effects of different light spectra and interaction of plant defenses and herbivores need to be tested across a broad range of plant groups. Resumen Los diodos emisores de luz a menudo se utilizan para sustituir y mejorar la luz fluorescente o incandescente para las plantas que se cultivan en entornos con clima controlado. Estas luces a menudo se eligen en lugar de otras fuentes de luz debido a la durabilidad de los diodos emisores de luz, su larga vida útil, su longitud de onda mejorada para especies específicas de plantas, sus costos de energía más bajos, su riesgo de seguridad contra el calor superficial más bajo y su capacidad más fácil de incorporarse a sistemas avanzados de control climático. Sin embargo, estudios previos han demostrado que las características de Sorghum bicolor (L.) Moench (Poaceae) se alteran bajo luces de diodos emisores de luz. Por lo tanto, cultivamos 4 cultivares de sorgo en cámaras de crecimiento con luces convencionales o con diodos emisores de luz. Las plantas estaban infestadas con el pulgón de la caña de azúcar, Melanaphis sacchari (Zehntner) (Hemiptera: Aphididae) o no estaban infestadas (control). El sorgo cultivado bajo luces de diodos emisores de luz era más corto y producía más hojas que eran más anchas que las de las plantas cultivadas bajo luces convencionales.

Since these interactions can bear a substantial cost for the signaler, selection may cause changes in their signals, possibly contributing to the evolution of the communication system. Understanding the life history of the interacting species, especially that of the eavesdropper, is essential to better quantify the selective pressures in these interactions. The katydid, Neoconocephalus triops L. (Orthoptera: Tettigoniidae), is parasitized by the lethal tachinid fly, Ormia lineifrons Sabrosky (Diptera: Tachinidae), in Florida. I collected N. triops in the field to characterize its parasitism by O. lineifrons and determine the efficiency of the fly's host use. The parasitism rate of N. triops was 48.2% and about half of the parasitized males (47.2%) were superparasitized. All parasitized katydids died and no larva that was the result of superparasitism survived the host's death. The average parasite load was 2.73 ± 1.20 larvae, and 49.5% of the fly pupae successfully developed into adult flies in 12.12 ± 0.60 d. Neoconocephalus triops also was parasitized by an undescribed species of Neomintho (Diptera: Tachinidae). The high superparasitism rate despite its low success suggests that O. lineifrons has not evolved traits to reliably distinguish between unparasitized and parasitized hosts. The high parasitism rate of N. triops suggests that O. lineifrons exerts substantial selective pressure on N. triops. However, the low developmental success of fly larvae may indicate that N. triops has evolved counter adaptations in its arms race with O. lineifrons, or N. triops might be a low-quality host.

Their attack leads to loss in plant production. Common blossom thrips, Frankliniella schultzei (Trybom), and red-banded thrips, Selenothrips rubrocinctus (Giard) (both Thysanoptera: Thripidae), are serious insect pests attacking various plants, such as tomato (Solanum esculentum Miller [Solanaceae]), mango (Mangifera indica Linnaeus [Anacardiaceae]), avocado (Persea americana Miller [Lauraceae]), and lotus flower (Nelumbo nucifera Gaertn. [Nelumbonaceae]). Currently, basic thrips control relies on synthetic insecticides. However, the toxicity of each existing insecticide for control of some specific pest species still has not been well established. This study evaluated and reported the toxicity of 6 insecticides (chlorantraniliprole, cypermethrin, carbosulfan, fipronil, abamectin, and spinetoram) for control of the 2 thrips species mentioned above. The evaluation was done by exposing 10 thrips to a bean dipped in insecticide, and mortality was recorded after 24 h of exposure under laboratory conditions. Spinetoram was the most toxic to F. schultzei with an estimated LC50 of 0.05 ng per µL. For red-banded thrips, S. rubrocinctus, the most toxic insecticides were abamectin, spinetoram, and fipronil, with LC50 values of 1.67, 1.85, and 4.23 ng per µL, respectively. On the other hand, the least toxic insecticide to common blossom thrips and red-banded thrips was chlorantraniliprole, with LC50 values of 270.51 and 641.08 ng per µL, respectively. Overall, among the tested chemicals, spinetoram was the most effective in controlling these pests. The findings from this study will benefit developers of insecticide management strategies in thrips control programs.

Leaves of 40-d-old seedlings were infested in micro-cages with 5 weevils per seedling. Eight plants were screened for each population to analyze insect mortality and leaf consumption. The experiment was replicated twice in 2 consecutive yr.
