EPINOTIA APOREMA PDF

Daijas Epinotia aporema The male forewing is mostly brown to reddish brown with a aporemz dorsum and large costal patch. The behaviour of each male was observed continuously aoorema 20 min, recording the first arm chosen and the number of entrances in both arms. Bol Univ Repub Fac Agron The parameters recorded were the time of mating onset and its length, age of the mating female and the number of mates per couple. Indeed, the description of the time pattern of pheromone emission will facilitate the collection and chemical characterization of the sex pheromones by dissections of the glands during the peak of female calling h aporeka the scotophase. Crocidosema aporema completes generations per year, with at least two generations occuring on soybean. Prior to mating, a sequence of events was observed in which the quiescent male responded to the calling female by approaching her while fanning his wings in the upright position, male and female then made contact with their antennae, and immediately turned to engage in mating Fig 4.

Daijar No courtship behaviour was observed when the males reached the mesh that separated the olfactometer from the tube holding the calling female. The Brazilian culture was obtained from individuals collected in Fazenda Rio Grande Parana and the Uruguayan insects were originally collected in La Estanzuela Colonia.

Prior to mating, a sequence of events was observed in which the quiescent male responded to the calling female by approaching her while fanning his wings in the upright position, male and female then made contact with their antennae, and immediately turned to engage in mating Fig 4. Multiplex PCR and quality control of Epinotia aporema granulovirus production. Humidified and pre-cleaned activated charcoal air was passed through the olfactometer at a total flow of 2.

Crocidosema aporema adults were obtained from two laboratory populations that were kept in similar conditions in our laboratories in Brazil and Uruguay. Knight A L Sexual biology and mating disruption of orange tortrix, Argyrotaenia citrana Lepidoptera: Male response was evaluated at eponotia using a single calling female in a Y-shaped olfactometer.

How to cite this article. We also provide evidence that this tortricid is monoandrous, and that pheromones are used in intersexual communication for mate finding.

Detection and kinetic analysis of Epinotia aporema granulovirus in its lepidopteran host by real-time PCR. Males that did not leave their glass tubes after 12 min were considered as non responsive. This posture is characterized by the raised wings, the abdomen curved down and the gland continuously exposed.

Our results show that even in the constant presence of a male during several nights, mated females did not tend to re-mate, which differs from other tortricid females alorema mate repeatedly Knight New York, Chapman and Hall, p. Most of the couples mated aporrema throughout the experiment, between the third and sixth night and during the middle of the dark phase. The bean shoot borer, Epinotia epinotka Lep. Epinotia aporema Last updated August The proportion of calling females was analyzed by a two-factor ANOVA in which the effects of female age and hour within the scotophase were evaluated as independent factors epimotia data transformed as arcsine p.

Chemical Identification and Male Behavioral Response. Epstein Interactive Keys developed e;inotia Lucid 3. Larval Morphology For information on the larva of Crocidosema aporemaplease consult the fact sheet and keys on LepIntercept — An identification epinotiia for intercepted Lepidoptera larvae. Crocidosema aporema is distributed throughout Central and South America.

While two related tortricids, P. Papers overview Semantic Scholar uses AI to extract papers important to this topic. Tortricidae in apple orchards treated with sex pheromone. Females were observed every 15 min for their calling behavior under a red light that was lit only during the observations. Alzugaray R, Ribeiro A Insectos en pasturas, p.

Likewise, the probability of mating is expected to increase as the calling period within the scotophase is lengthened. Material and Methods Insects. Crocidosema aporema originated epinotai Costa Rica, and is now widely distributed throughout South America. Our data will be used to optimize the collection of female sex pheromones for chemical characterization in order to develop a monitoring tool for this pest. Aplrema basic findings concerning the mating behaviour of C.

New York, Academic Press, p. Our results describe for the fi rst time the temporal pattern associated to the reproductive behaviour of C.

Sex Pheromone of the Bud Borer Epinotia aporema: Engaging in reproduction as early as possible is likely to be advantageous for moths with short adult lives such as C.

The males moved epinotiia within the olfactometer during the min observation period, entering several times in both arms. Such variation may respond to various predictable ecological conditions, to which different species are adapted. Rev Fac Agron The behaviour of each male was observed continuously during 20 min, recording the first arm chosen and the number of entrances in both arms. Females adopted a characteristic calling posture, extruding the pheromone gland from the tip of the abdomen.

Females lay eggs on glabrous nodes of the soybean plant or other leguminous host. Services on Demand Journal. Males, in turn, display a typical wing fanning response in the presence of a calling female, and are attracted to the females in a Y-tube olfactometer, indicating the presence of volatile pheromones.

Tortricids of Agricultural Importance by Todd M. The behavioural sequence observed during courtship was not unusual for a moth. It is also likely present in southern Mexico most recent records are from Chiapas in and the Caribbean.

Its importance has increased during the last decade owing to the significant growth of soybean production in the region. Monitoring of E. We analyzed the female-produced sex pheromone so as to develop monitoring traps and explore pheromone-based control methods. We analyzed pheromone gland extracts by combined chromatographic, spectrometric, and electrophysiological methods.
