After herbivore attack, plants express inducible resistance-related traits activated by hormones, mainly jasmonic acid (JA) and salicylic (SA). Methyl jasmonate (MeJa) is a biologically active methyl ester of JA. Exogenous applications JA, SA, MeJa induce responses similar to herbivory insects. In this study, rice, Oryza sativa L. (Poaceae), were treated with two concentrations (2 5 mmol L-1 ), SA (8 16 ) evaluate effects elicitation on resistance the rice stink bug (RSB) Oebalus pugnax...
ABSTRACT Agriculture is an important sector of the economy but consumes significant amounts water, a precious and limited natural resource. However, superabsorbent polymers combined with essential oils (EO) can be used to obtain sustained release nutrients improved soil water retention capacity by hydrogel, they act as repellence in crops farm crop enemies. Were synthesized, poly(vinyl alcohol) (PVOH) hydrogels, crosslinked organics acids (malic tartaric) EO incorporated (clove, orange,...
The lesser mealworm, Alphitobius diaperinus Panzer 1797 (Coleoptera: Tenebrionidae), is a cosmopolitan insect pest affecting poultry production. Due to its cryptic behavior, insecticide control usually not efficient. Thus, sustainable and effective methods would have an enormous positive impact in aim of this study was confirm the identity male-produced aggregation pheromone for Brazilian population A. evaluate biological activity behavioral assays. Six male-specific compounds were...
Abstract BACKGROUND Nanotechnology has recently allowed the production of formulations for controlled release active ingredients. In present study, electrospinning technique was used to produce nanoscale dispensers attract‐and‐kill strategies. Non‐woven nanofibres containing insecticide (cypermethrin) and ( E )‐8,( Z )‐8‐dodecenyl acetate )‐8‐dodecanol (0.87 mg L −1 ), main components Grapholita molesta (Lepidoptera: Tortricidae) (Busck) pheromone, were evaluated in laboratory experiments....
 The Mediterranean fruit fly (medfly), Ceratitis capitata (Wied.) is considered a serious pest of citrus fruits in the southeast Brazil because direct economic impact they have on production and quarantine restrictions for exports. Monitoring detection medfly, using food bait synthetic attractants, key step towards signalling need management control. aim this study has been to verify attractiveness innovative nanofiber formulations with Trimedlure (TML) male C. laboratory field cage...
First records of Glyphepomis adroguensis (Hemiptera, Pentatomidae) and its parasitoid, Telenomus podisi (Hymenoptera, Platygastridae), on rice fields in Rio Grande do Sul, Brazil. Eggs, nymphs, adults Berg, 1891 were observed for the first time (Oryza sativa L.) Charqueadas (29º59'S, 51º31'W) Eldorado Sul (30º02'S, 51º23'W) state, Ashmead, 1893 Platygastridae) was found G. eggs.
Antennal sensilla of Anastrepha fraterculus (Wied.) were examined using scanning electron microscopy. In the flagellum, there are trichoid, basiconic, clavate type I and II, styloconic microtrichia. Only microtrichiae chaetica observed in scape pedicel. The number flagellum was similar between sexes. At apex a higher density trichoid an absence sensilla, while basiconic more abundant proximal region.
The rice stem bug, Tibraca limbativentris Stal. (Hemiptera: Pentatomidae) is one of the most important pests crops, especially irrigated crops. Plant defence strategies against these bugs may involve emission chemical compounds, which are released following herbivore attacks, directly or indirectly harming pest performance. aim this study was to evaluate influence constitutive and herbivory-induced volatiles from plants (Oryza sativa L.) on behavioural responses T. adults egg parasitoids...
Abstract The egg parasitoid Telenomus podisi is a natural control agent of pentatomids, including Euschistus heros and Tibraca limbativentris , success parasitism dependent upon the finding host. We tested influence host volatiles synthetic sex pheromone (zingiberenol) T. limbativentri s on chemotaxic behaviour as well as, impact original selection. used mated female (48 h old) that emerged from eggs or E. . bioassays related to chemotaxy were performed in Y-tube olfactometer and, success,...
Halyomorpha halys (Stål) (Heteroptera: Pentatomidae), the brown marmorated stink bug (BMSB), is an invasive pest in U.S., where it has been largely unaffected by natural enemies. Using rinsed and unrinsed, frozen fresh egg masses laboratory bioassays, we studied how surface chemicals on eggs of H. might suppress parasitism native North American scelionid parasitoids, Telenomus podisi Ashmead Trissolcus erugatus Johnson (Hymenoptera: Scelionidae). Parasitism fresh-rinsed fresh-unrinsed was...
The reproductive success of the oriental peach moth was evaluated in four experiments: 1) assessment mating duration, fecundity, fertility and longevity females paired with virgin immediately mated males; 2) spermatophore size, up to times 3) receptivity additional copulations after or males, effects this behavior female longevity; 4) influence insects age output. Males (33%) could copulate a previous copula. They were fertile until fourth mating, but only first copula they transferred...
This study aimed to identify and quantify the compounds present in abdominal glands of Alphitobius diaperinus Panzer, 1797 (Coleoptera: Tenebrionidae) evaluate influence these on its behavior. The extraction volatiles was made by dissection (10 individuals per sex) air entrainment (200 insects sex), they were analyzed gas chromatography-flame ionization detector, chromatograph-mass spectrometer, chromatograph-electroantennography detector (GC-EAD). behavior conspecifics evaluated a four-arm...
Abstract Indirect plant defense may be mediated by volatiles released after oviposition and/or herbivory or exogenous application of hormones such as methyl jasmonate (MeJa), signaling host presence to parasitoids. There is still incipient information regarding phytohormone action on crop defense, especially among tomato plants ( Solanum lycopersicum L., Solanaceae) and the parasitoid Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae). We aimed evaluate T. chemotaxis parasitism in...
O percevejo-do-colmo, Tibraca limbativentris Stål (Hemiptera: Pentatomidae), é uma importante praga da cultura do arroz no Brasil. presente trabalho objetivou registrar a ocorrência de parasitoides ovos T. em lavoura irrigado, situada município Eldorado Sul, Rio Grande Sul. A área (603 m2) foi vistoriada semanalmente, 21/01/2010 03/03/2010, coletando-se posturas percevejo-do-colmo. Constatou-se somente Telenomus podisi (Ashmead) (Hymenoptera: Platygastridae) como parasitoide ovos, sendo o...
Abstract Plants have developed chemical defence strategies which can either be triggered in response to herbivory or by the exogenous application of phytohormones, such as methyl jasmonate (MeJa). Tuta absoluta is main pest associated with tomatoes worldwide. However, studies on impact plant hormones this system are still scarce. This study aimed evaluate chemotactic responses and oviposition T. towards tomato plants induced MeJa injuries. We conducted dual‐choice olfactometry bioassays...
O parasitoide de ovos Telenomus podisi Ashmead, 1893 é um importante agente controle natural percevejos e seu sucesso parasitismo está associado à habilidade para a localização do hospedeiro, sendo aprendizagem memória dos fatores que podem influenciar esta interação. trabalho avaliou capacidade tempo retenção da T. ao extrato capim-limão [Cymbopogon citratus (DC.) Stapf. (Poales, Poaceae)], em diferentes estágios desenvolvimento fase imatura. Ovos Euschistus heros (Fabricius, 1798)...
