“…The results of the present work show that the release of the O. nubilalis pheromone component reduced Albajes et al, 2002;Sole et al, 2008). However, as the main objective of this work was not to put a mating disruption system into practice but to confirm the cross-antagonistic action on pheromone perception by males of the two corn borers, the worst-case situation was chosen.…”

Maize (Zea mays L.) yield in several countries of the Mediterranean basin is affected by the Mediterranean corn borer, Sesamia nonagrioides Lefèbvre, in addition to the more ubiquitous European corn borer, Ostrinia nubilalis Hübner (Eizaguirre et al., 2004). The second flight and partially also the third flight of both species coincide and therefore adults of the two species can interact through their pheromone systems. AbstractIn previous studies, we demonstrated cross-antagonism in pheromone perception between pheromone components of the two corn (Zea mays L.) borers Sesamia nonagrioides Lefèbvre (Lepidoptera: Noctuidae) and Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae) in the laboratory and in the field. The two pheromone components identified as responsible for this cross-antagonism were Z 11-16:Ald, a minor component of S. nonagrioides pheromone, and Z 11-14:Ac, the main component of the pheromone of the Z-strain of O. nubilalis, which inhibited the response of O. nubilalis and S. nonagrioides, respectively. Here, we study this antagonism phenomenon in the field by air permeation of maize plots with each of the two components separately and measurement of mating in caged couples of the two corn borers on treated and untreated plots during three years. A significant reduction in mating rates was observed on the permeated plots: 7% for S. nonagrioides and 12% for O. nubilalis. When dispenser charges (200 ng) were increased by 50% and 75% in the third year, no decrease in mating rates was recorded at either of the increased concentrations. On the other hand, the use of large cages resulted in an increase of 8% to 12% in the percentage of unmated females in each of the two corn borers suggesting that at more realistic field corn borer densities, 0,1 couples/plant instead of the 2 couples/plant used in this experiment, cross-antagonism in the two corn borers could be higher than that recorded in small cages.Additional key words: inhibition; maize; mating disruption. Resumen Comunicación corta. Antagonismo mutuo entre las feromonas de dos taladros simpátricos, Sesamia nonagrioides y Ostrinia nubilalis, en condiciones de campoEn trabajos previos mostramos el antagonismo cruzado en la percepción feromonal de dos taladros del maíz (Zea mays L.), Sesamia nonagrioides Lefèbvre (Lepidoptera: Noctuidae) y Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae) en el laboratorio y en experimentos de campo. Los dos componentes feromonales identificados como responsables de este antagonismo cruzado fueron Z 11-16:Ald, componente minoritario de S. nonagrioides y Z 11-14:Ac, el componente principal de la raza Z de O. nubilalis, que inhibieron la respuesta de O. nubilalis y S. nonagrioides, respectivamente. Ahora hemos estudiado este mismo fenómeno en el campo a lo largo de tres años impregnando el aire de las parcelas con cada uno de los componentes citados y midiendo el apareamiento de parejas enjauladas de cada especie en parcelas tratadas y no tratadas. Se observó una reducción del porcentaje de apareamientos en las ...

“…Synthetic sex pheromones can be highly effective, such as their use in the eradication of European gypsy moths, Lymantria dispar, via mating disruption (Gaston et al 1967;McNeil 1991;Reardon et al 1998). Similarly, pheromone-based traps greatly improve management of invasive species, such as the European corn borer, Ostrinia nubilalis, which causes significant economic losses in agriculture on multiple continents (Albajes et al 2002;Bohnenblust et al 2014). In pest vertebrate species, synthetic sex pheromones have been successfully implemented in traps for multiple species of rodents [e.g., brown rats, Rattus norvegicus (Takács et al 2016); house mice, Mus musculus (Musso et al 2017;Takács et al 2017)].…”

Feminization of Male Brown Treesnake Methyl Ketone Expression via Steroid Hormone Manipulation

et al. 2018

Pheromones are useful tools for the management of invasive invertebrates, but have proven less successful in field applications for invasive vertebrates. The brown treesnake, Boiga irregularis, is an invasive predator that has fundamentally altered the ecology of Guam. The development of control tools to manage Boiga remains ongoing. Skin-based, lipophilic pheromone components facilitate mating in brown treesnakes, with females producing the same long-chain, saturated and monounsaturated (ketomonoene) methyl ketones known to function as pheromones in garter snakes, Thamnophis sirtalis. Boiga also express novel, diunsaturated methyl ketones (ketodienes) with a purported function as a sex pheromone. In our study, we implanted 17 β-estradiol in adult male brown treesnakes in order to manipulate methyl ketone expression as sex attractants, an effect that would mirror findings with garter snakes. Specifically, estrogen promoted production of two ketomonoenes, pentatriaconten-2-one and hexatriaconten-2-one, and suppressed production of one ketodiene, heptatriacontadien-2-one. In bioassays, estrogen-implanted males elicited tongue-flicking and chin rubbing behavior from unmanipulated males, though the responses were weaker than those elicited by females. On Guam, wild males exhibited greatest responses to whole female skin lipid extracts and only weak responses to the methyl ketone fractions from females and implanted males. Our results suggest that sex identity in brown treesnakes may be conferred by the ratio of ketomonoenes (female) to ketodienes (male) from skin lipids and may be augmented by a sex-specific endocrine signal (estradiol). However, a blend of long-chain methyl ketones alone is not sufficient to elicit maximal reproductive behaviors in male Boiga.

“…In this case, an optimal timed spray for gray looper could help reduce the number of sprays, reduce the intensity of each future generation of moths, and directly lessen the damage to soybean and cotton. Sticky traps baited with pheromone specific for Noctuidae have been used for mating disruption of the Mediterranean corn borer, Sesamia nonagrioides [3] and diamondback moth, Plutella xylostella [4]; tracking adult emergence of corn earworm, Helicoverpa armigera [5], and monitoring distribution of copitarsia worm Copitarsia declora Guenée [6]. Mating disruption in cotton and soybean is currently cost prohibitive ($125 g/ac, ISCA Technologies), but use of pheromone traps for decision of a precise application of insecticide at egg or larval stage could be cost effective by reducing number of sprays [7].…”

Noctuid moths include economic species of importance such as the soybean podworm, black cutworm, soybean looper, and fall armyworm. The gray looper feeds on a wide variety of low-growing plants including tobacco, soybean, cotton, clover, and common wheat. Soybean looper can likewise be found in soybean and cotton. To monitor the flights and numbers of gray and soybean loopers in Southeast Missouri, funnel traps were baited with Autographa gamma or Pseudoplusia includens lures and dispensed on 1 May 2015 in 8 randomly selected soybean fields. Traps were monitored weekly (1 May -1 Oct 2015). Degree days began at biofix, and a single sin method with a lower threshold of 15˚ was used to calculate accumulative degrees days. Temperature data was obtained from NOAA. Each peak flight was assigned accumulative number of degree days. Degree days for the current soybean looper model (egg to adult, 435dd) were compared with estimated models for gray and soybean loopers. These models were developed by averaging accumulated degree days between counties for peaks 1 -4 (204, 496, 937, and 1527 degree-days, gray looper) and for peaks 1 -5 (349, 641, 962, 1258, and 1540 degree days, soybean looper). Soybean looper model was accurate for flights 1 -3 for gray looper. For soybean looper management, the new soybean looper model worked best for estimating future peak flights. This confirmation of model data should help growers with their insecticide application decisions.
