The olfactory system of male and female Spodoptera frugiperda (J. E. Smith) was studied by examining the morphology distribution antennal sensilla determining responses both sexes to conspecific sex pheromone components plant volatiles using electroantennography (EAG). Seven types were observed on flagellum antennae: trichodea, chaetica, coeloconica, styloconica, auricilica, squamiformia, basiconica. Only one type trichodea found antennae sexes, but these more abundant than female. EAG...

Se evaluó el daño ocasionado por complejo de barrenadores la caña azúcar (CBCA) en este cultivo Morelos, México, desde etapa macollamiento hasta producción tallos listos para molienda. La variedad Lt 96-9 fue significativamente más infestada al final que las variedades ITV92-1424 CP 72-2086. En municipio Tlaquiltenango hubo mayor infestación CBCA Amacuzac. un año y con intensidad cuatro años. macollamiento, no diferencia significativa relación respecto a variedad, ciclo ubicación del...

We designed 2 papaya groves to test the concepts of trap cropping and border trapping control Toxotrypana curcicauda. Intensive fruit sampling in grove 1 indicated that degree infestation decreased as distance from native vegetation (source flies) increased. Rows planted 10 m away main block trees (trap crop) exhibited greatest puncture damage larval both experimental groves. Fruit was highest after rainy season over spatially aggregated. conclude designing a such way crop consisting plants...

The number, external morphology, and distribution of antennal sensilla Zamagiria dixolopella Dyar were determined by light scanning electron microscopy. flagellum both sexes has six types sensilla: trichodea (subtypes I II), chaetica, coeloconica, styloconica, auricillica, squamiformia. There is sexual dimorphism in the antennae Z. dixolophella. male antenna a tuft hairs or modified scales at its base one protuberance for each segment first seven segments, below scales. These structures are...

We quantified within-orchard distribution patterns and diel of oviposition, male calling, mating, feeding, resting behaviors wild papaya fruit flies, Toxotrypana curvicauda Gerstaecker, in experimental commercial orchards the states Morelos Veracruz, Mexico. Essential resources (e.g., oviposition substrates, sites to perform sexual activities, food, shelter) were identified both plantations adjacent native vegetation. In monocrops, T. adults fly back forth between vegetation plantations....

Antennal morphology, types of sensilla, and their distribution have been investigated in Talponia batesi Heinrich (Lepidoptera: Tortricidae) by using scanning electron light microscopy. T. antenna is filiform segmented both sexes, consisting the three usual components: scape, pedicel, flagellum. length was greater females than males. Five sensilla were identified on antennae sexes: trichodea, chaetica, styloconica, coeloconica, auricillica. All present ventral side antenna, coeloconica...

Five types of sensilla were found on the antennae adult Copitarsia consueta (Walker) (Lepidoptera: Noctuidae) by scanning electron microscopy and light microscopy. Those trichoidea, coeloconica, styloconica, basiconica squamiformia. Two sexually dimorphic trichodea found; type I is in border sensory field flagellar segments present only male antennae. This suggests that sensillum may contain receptor sites for female sex pheromone. Type II located within ventro-medial sensillar where it...

The antennal flagellum of the melolontid beetle Phyllophaga obsoleta Blanchard consists three terminal plates lamellae: proximal, middle, and distal. Six types sensilla were identified on internal external surfaces lamellae from both sexes: placodea (PLAS), basiconica (BAS), coeloconica (COS), auricilica (AUS), chaetica (CHS), trichodea (TRS). first four have been considered as chemoreceptor last two mechanoreceptor sensilla. each present in club sexes mapped by scanning electron microscopy....

The physic nut, Jatropha curcas L. (Mal phighiales: Euphorbiaceae), is one of 75 plant species suitable for the production biodiesel. Moreover, it considered as having great agro industrial potential worldwide, on account its obtaining high quality oil, and ease cultivation (Martin & Mayeux 1984; Azan et al. 2005). Plantings J. have been es tablished around world, more recently in various states Mexico (Michoacan, Chiapas, Puebla, Yucatan, Veracruz, Guerrero, Oaxaca Morelos) with principal...

Abstract For the first time, antennal sensorial organs of Leptoglossus zonatus (Dallas) (Heteroptera: Coreidae) are described through scanning electron microscopy. The antennae formed by a scape, pedicel, and flagellum that is composed two flagellomeres main bearer organs. Five types sensory structures were identified: Trichoid sensilla, basiconic coeloconic campaniform placoid sensilla. sensilla divided into five subtypes. large striated trichoid have almost straight longitudinally cuticles...

Abstract The antennal sensilla of Anastrepha serpentina (Wiedemann) (Diptera: Tephritidae) adults were studied by means scanning electron microscopy. Both sexes have the same form and number segments. scape pedicel are covered entirely microtrichia. In distal part both segments, a series longitudinally striated hairs was observed, originating in flexible socket ending pointed tip. Six types observed funiculus: 1) thick-walled multiporous pitted subtype I II, 2) thin-walled long medium length...

We tested the predatory capacity of newly-hatched or newly-molted Chrysoperla comanche (Banks) and externa (Hagen) larvae after a 24 h fasting period on adults Frankliniella occidentalis (Pergande) that were feeding tomato plants (at vegetative blooming stage) under glasshouse conditions. also recorded fruit damage by thrips. Both Chysoperla spp. depredated similar number F. (thrips) regardless phenological stage plant. Second third instar both species consumed significantly more thrips than...

Adults of the papaya fruit fly, Toxotrypana curvicauda Gerstaecker, living in wild vegetation Yautepec, Morelos, Mexico, were captured using McPhail traps baited with pineapple juice or brown sugar. Maximum capture peaks occurred during August and November afternoon. Baits most effective when aged over a 4-d period. Traps sugar highest number adults, both baits more attractive to females than males. Potential use these for pest management research is discussed, considering that this first...

The calling behavior of mass-reared and wild males Anastrepha serpentina (Wiedemann) (Diptera: Tephritidae) was studied both in the laboratory field cage tests. In laboratory, density (1, 5, 10 per container), age, hour day significantly affected behavior. Mass-reared called independently density, whereas only at densities 5 individuals. Males strains started when they were 5-7 d old. daily pattern male similar strains, starting 0730 hours, reaching a peak 1330-1630 hours. Field tests showed...

The leaf-footed bug Leptoglossus zonatus (Dallas) (Heteroptera: Coreidae) is an important pest in the Americas. However, no preference of colors, sexual behavior nor aggregation pheromone has been reported, which can be used for detection, monitoring, and control purposes. In laboratory we tested attractiveness white, violet, blue, green, yellow, orange color to nymphs adults (mated unmated) found that most were attracted remained longer on blue green colored cards than other colors tested....

The metathoracic scent gland of 25-day-old adults both sexes the leaf-footed bug, Leptoglossus zonatus (Dallas) (Heteroptera: Coreidae), are described based on optical microscopy analysis. No sexual dimorphism was observed in glandular composition this species. is located anteroventral corner pleura between middle and posterior coxal pits. opening to outside very wide permanently open as it lacks a protective membrane. In internal part, there pair glands that consist piles intertwined...

The biological activity of 4 Mexican isolates (SeSIN6, SeSIN8, SeSLP6, and SeSLP8) the homologous multiple nucleopolyhedrovirus SeMNPV their effects on development beet armyworm, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae), were studied. An exotic isolate from United States (SeUS2) was used as a reference. Early third-instar larvae inoculated with 5 × 106 occlusion bodies per mL, resulting in 78% mortality for SeUS2 approximately 90% each at 144 h post-inoculation. At 168...
