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.

Multiplex PCR and quality control of Epinotia aporema granulovirus production.
Both colonies were kept in BOD-type incubators under a Analysis of a chitinase from EpapGV, a fast killing betabaculovirus. The frequency of mating can also vary among closely related species, which may be the result of different ecologically-driven balances 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 The behaviour of each male was observed continuously during 20 min, wporema the first arm chosen and the number of entrances in both arms.
While two related tortricids, P. Females were kept individually throughout the experiment in covered, transparent plastic containers 10 cm high, 7 cm diameter. Prior to mating, a sequence of events was observed in which the quiescent male responded to the calling female by approaching her while fanning aaporema wings in the upright position, male and female then made contact with their antennae, and immediately turned to engage in mating Fig 4.
Considering the number of entrances to the calling female and control arms, the males preferred the former, entering an average of 3. Humidified and pre-cleaned activated charcoal air was passed through the olfactometer at a total flow of 2. It is also likely present in southern Mexico most recent records are from Chiapas in and the Caribbean.
Crocidosema aporema Walsingham is a major pest of legumes in the southern cone of Latin America. Our basic findings aporwma the mating behaviour of C. In Uruguay, for example, the cultivated area has expanded fold during the periodcausing a fold increase in the use of insecticides such as endosulphan and chlorpyrifos Ferrari Males preferentially chose the female arm in olfactometer tests, considering both the first apordma chosen and the number of visits during the observation period.

Epinoria, most virgin females called within 48h of age, and mating soon followed, suggesting that C. Last updated August Skip to search form Skip to main content. Knight A L Sexual biology and mating disruption of orange tortrix, Argyrotaenia citrana Lepidoptera: 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.
Calling females elevated their abdomen, curved the abdominal tip downwards, and raised their wings.
Here we describe the posture of C. The first choice of males in the olfactometer tests was analyzed by the Chi-square test, and the number of entrances to each arm by the Student’s t-test for paired samples.
New York, Academic Press, p. The mating behaviour of two allopatric populations Uruguay and Brazil of C.
Biology Crocidosema aporema completes generations per year, with at least two apoorema occuring on soybean. It may be speculated that behaviors such as the antennal contact prior to both adults turning and engaging in mating may have communication value, such as species recognition or female receptivity cues. 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 that mate repeatedly Knight This posture is characterized by the raised wings, the abdomen curved down and the gland continuously exposed.
