Abstract Although a large amount of data have been published in past years on the taxonomic status Anastrepha fraterculus (Wiedemann) species complex, there is still need to know how many this complex comprises, distribution each one, and their distinguishing features. In study, we assessed morphometric variability 32 populations from A. located major biogeographical areas Neotropics. Multivariate techniques for analysis were applied measurements 21 variables referring mesonotum, aculeus,...

Previous morphometric studies based on linear measurements of female structures the aculeus, mesonotum, and wing revealed existence seven morphotypes within Anastrepha fraterculus cryptic species complex along Neotropical Region. The current research followed geometric approaches in 40 population samples nominal A. (Wiedemann) spread throughout Meso-American Pacific dominions (including Mexico, Central America, Venezuela, Colombia, Ecuador, Peru). goals were to explore phenotypic...

A new species of the genus Beebeomyia Curran found in central Veracruz (Mexico) is described, including characters male and female terminalia, a key to identification known provided. This was feeding within inflorescences Dieffenbachia oerstedii Schott (Araceae). Larvae were throughout inflorescence, with proportion nearly three times higher (bottom) than (top) section. The life cycle from larval stage adult emergence takes place an average time 42 days, while pupation occurs inflorescence....

Discriminant function and cluster analyses were performed on 19 morphometric variables of the aculeus, wing mesonotum to determine whether populations Anastrepha fraterculus (Wiedemann) from different parts Mexico could be distinguished South America. Samples collected seven localities across Mexico, two Brazil, one each Colombia Argentina. Results showed there statistically significant differences between Mexican American with respect aculeus (tip length, length serrated section, mean...

An integrative multidisciplinary approach was used to delimit boundaries among cryptic species within the Anastrepha fraterculus complex in Brazil. Sexual compatibility, courtship and sexual acoustic behaviour, female morphometric variability, variation for mitochondrial gene COI, presence of Wolbachia were compared A. populations from Southern (Vacaria, Pelotas, Bento Gonçalves, São Joaquim) Southeastern (Piracicaba) regions Our results suggest full mating compatibility region partial...

The study of the species complex Anastrepha fraterculus (Af complex) in Brazil is especially important a taxonomical, evolutionary and pest management context, because there are evidences that some them may occur sympatry. In this review, we analyzed main results supporting three cryptic Brazil. taxonomical phylogenetic relationships based on eggshell morphology, adult morphometrics, as well cytotaxonomy genetic differentiations discussed. We also review available information sexual behavior...

Anastrepha fraterculus (Wiedemann) is recognized as a pest of citrus, apples, and blackberries in South America. In Mexico, it mainly found fruit the family Myrtaceae has never been reported infesting citrus. Here, we sought to determine whether females stemming from Mexican A. populations (collected state Veracruz) would lay eggs 'Valencia' oranges 'Ruby Red' grapefruit and, if so, larvae hatch develop. We worked under laboratory seminatural conditions (i.e., gravid released fruit-bearing,...

Within the Neotropical genus Anastrepha , nominal species fraterculus is widely distributed from Mexico through northern Argentina. Currently it believed to comprises a complex of at least eight cryptic species—known as (AF complex)—three which occur in Brazil: A . sp.1 aff. sp.2 and sp.3 In this study, we present results broad integrated analysis multiple biological attributes samples three collected sympatric areas. Analyses mitotic chromosomes confirm that all them differ sex chromosomes,...

The occurrence of cryptic species among economically important fruit flies strongly affects the development management tactics for these pests. Tools studying not only facilitate evolutionary and systematic studies, but they also provide support fly quarantine activities. Previous studies have shown that South American fly, Anastrepha fraterculus, is a complex species, few been performed on morphology its immature stages. An analysis mandible shape linear morphometric variability was applied...

The relationships between Anastrepha species and their host plants are recorded analyzed from a study carried out in natural tropical community of Mexico (Estacion de Biologia Tropical Los Tuxtlas, Veracruz). We sampled fruits 55 plant the rain forest found following associations: Tapirira mexicana Marchand was infested with A. sp. obliqua (Macquart); Spondias radlkoferi J. D. Smith obliqua; Tabernaemontana alba Mill. cordata Aldrich; Quararibea funebris (Llave) Vischer crebra Stone; Inga...

Abstract Field cage tests were carried out to determine the sexual competitiveness, copulation duration and sperm transfer of sterile wild Mexican fruit fly, Anastrepha ludens (Loew), males that treated or not with Beauveria bassiana (Balsamo) Vuillemin conidia immediately before mating tests. No significant differences in competitiveness found between untreated conidia, indicating presence did significantly reduce performance. However, both types less competitive than males. There no...

The West Indian fruit fly, Anastrepha obliqua, is one of seven species quarantine importance its genus and the most economically important fly pests in Colombia. taxonomic status this a key issue for further implementation any pest management program. Several molecular studies have shown enough variability within obliqua to suggest could be revised; however, there are no morphological supporting hypothesis. aim work was describe Colombian populations comparing with that other samples from...

The South American fruit fly Anastrepha fraterculus (Wiedemann) is a complex of cryptic species, the so-called "Anastrepha complex", for which eight morphotypes are currently recognized. A previous analysis ITS1 in samples complex, while revealing high distinctiveness among from different localities America, Central and Mexico, no direct association was made between sequence type morphotype. In present report, correlated morphometry data involved individuals belonging to same population...

In order to carry on the detection and species inventory of hymenopteran parasitoids associated with fruit flies, we examined various tropical fruits growing at Southern region Yucatan. During a yearly cycle (Jun 2000 Jun 2001), 9 host (including some varieties) were collected by 2 different methods. The first method involved weekly collection ripened that transported laboratory ("Fruit-Lab"); second was placed ground below tree canopy ("Fruit-Beds"), which remained in field for two weeks,...

The genus Blepharoneura currently contains 52 described species distributed throughout the Americas. Currently, 16 are recorded from Mexico, of which 13 belong to femoralis group. In this study we describe six new group several localities in Mexico: B. martyae, n. sp.; alleni, zapoteca xalapensis, isabelae, and dzuli, sp. A key for identification all is also provided, based on modifications originally published by Norrbom Condon (2010) include here.

The morphology of the third-instar larva Anastrepha leptozona Hendel is characterized using optical and scanning electron microscopy. antennomaxillary complex, oral ridges, labium, stomal sensory organ, cephalopharyngeal skeleton, anterior posterior spiracles caudal segment are described illustrated. Mature larvae A. present a "ventral sclerite" below pharyngeal sclerite which for first time in species.
