Scientific Name, Epinotia aporema [TAX]. Lineage, cellular organisms; Eukaryota; Opisthokonta; Metazoa; Eumetazoa; Bilateria; Protostomia;. Epinotia aporema granulovirus (EpapGV) is a fast killing betabaculovirus that infects the bean shoot borer (E. aporema) and is a promising. A granulovirus (GV) isolated from Epinotia aporema (Lepidoptera: Tortricidae)—a major soybean pest—was studied in terms of its main.

Females were observed every 15 min for their calling behavior under a red light that was lit only during the observations. Likewise, the probability of mating is expected to increase as the calling period within the scotophase is lengthened. Female genitalia are characterized by a pair of rounded pockets on sternum VII and a large rounded corpus bursae with two signa. Analysis of a chitinase from EpapGV, a fast killing betabaculovirus.

Revista Chilena de Historia Natural. Our basic findings concerning the mating behaviour of C. Pupation occurs in the soil or in rolled leaves.

Indeed, the description of the time pattern of pheromone emission will facilitate the collection and epinoita characterization of the sex pheromones by dissections of the glands during the peak of aporwma calling h into the scotophase. Tortricidae in apple orchards treated with sex pheromone.

In Uruguay, for example, paorema cultivated area has expanded fold during the periodcausing a fold increase in the use of insecticides such as endosulphan and chlorpyrifos Ferrari Rev Fac Agron The mating behaviour of two allopatric populations Uruguay and Brazil of C.

The behaviour of each male was observed continuously during 20 min, recording the first arm chosen and the number of entrances in both arms.

The olfactometer was an all-glass Y-maze with equal arms 17 cm long, 3 cm diameter.

Ann Entomol Soc Am Such variation may respond to various predictable ecological conditions, to which different species are adapted. In Smith R L eds Sperm competition and the evolution of animal mating systems. Females lay eggs on glabrous nodes of the soybean plant or other leguminous host. Most of the couples mated once throughout the experiment, between the third and sixth night and during the middle of the dark phase.


Interestingly, our data suggest that older females tend to begin calling earlier in the scotophase, thereby increasing the calling period.

Multiplex PCR and quality control of Epinotia aporema granulovirus production.

Larval Morphology For information on the larva of Crocidosema aporemaplease consult the fact sheet and keys on LepIntercept – An identification resource for intercepted Lepidoptera larvae. Calling females elevated their abdomen, curved the abdominal tip downwards, and raised their wings. The behavioural sequence observed during courtship was not unusual for a moth. 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 proportion data transformed as arcsine p.

Drummond B A I Multiple mating and sperm competition, p. 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.

Tortricidae under laboratory conditions. An immunochemical method for quantitation of Epinotia aporema granulovirus EpapGV. Multiplex PCR and quality control of Epinotia aporema granulovirus production.

In most cases it was possible to observe the putative pheromone gland extruded from the tip of the abdomen Fig 1. Both males and females increase their flight activity upon the onset of the scotophase, and quickly return to quiescence at the beginning of the photophase.

No courtship behaviour was observed when the males reached the mesh that separated the olfactometer from the tube aporeja the calling female.

J Econ Entomol Half of the males did not move from their original tubes, and were not taken into consideration. The male forewing is mostly brown to reddish brown with a pale dorsum and a;orema costal patch. Tortricids of Agricultural Importance by Todd M.

Multiplex PCR and quality control of Epinotia aporema granulovirus production.

No pulsation of the gland or obvious wing fluttering was observed. Crocidosema aporema originated in Costa Rica, and is now widely distributed throughout South America. Identical glass tubes were attached to each of the test epinotai, one holding a single virgin female in calling posture days old and the other empty to serve apoeema control arms were alternated between tests.


Papers aporma Semantic Scholar uses AI to extract papers important to this topic. Both colonies were kept in BOD-type incubators under a The aporrma step in order to develop a pheromone-based monitoring tool for C. Characterization of a granulovirus isolated from Epinotia aporema Wals.

However, most virgin females called within 48h of age, and mating soon followed, suggesting that C. In soybean, the larvae feed on vegetative plant parts affecting the normal growth of the plant. How to aporwma this article. Males have several secondary sexual structures including a forewing costal fold and black scaling on the hindwing. Tortricidae in La Plata, Argentina. Humidified and pre-cleaned activated charcoal air was passed through the olfactometer at a total flow of 2.

Genome of Epinotia aporema granulovirus EpapGVa polyorganotropic fast killing betabaculovirus with a novel thymidylate kinase gene.

Knight A L Sexual biology and mating disruption of orange tortrix, Argyrotaenia epintia Lepidoptera: Here we describe the posture of C. 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, aporma immediately turned to engage in mating Fig 4. Males and females were placed in the glass tubes 3h prior to conducting the experiments, and the tube holding a calling female was attached to the arm of the olfactometer 30 min before the onset of the observation period.

J Entomol Soc British Columbia Crocidosema aporema adults were obtained from two laboratory populations that were kept in similar conditions in our laboratories in Brazil and Uruguay.

The frequency of mating can also vary among closely related species, which may be the result of different ecologically-driven fpinotia between direct or genetic benefits obtained by the females at mating, and the various costs associated with it, such as predation or the transmission of diseases Drummond
