“…But in case of the present study, all the other variables (environment and diet) were kept constant, so, the phenotypic variability due to the existence of genetic differences amongst the populations cannot be ruled out, as also hinted by Chakravarty et al (2020). Similarly, Canal et al (2018) observed significant morphological variability in geographically isolated Colombian populations of the fruit fly, Anastrepha fraterculus (Wiedemann) reared under the same laboratory conditions, and thus also concluded about possible involvement of genetic factors in the expression of such differences.…”

Phenotypic variability in the Old World bollworm, Helicoverpa armigera (Hübner) populations in India

Helicoverpa armigera (Hübner) is one of the most prominent polyphagous species of the Heliothinae pest complex that inflicts severe damage to a wide range of crops in India. Knowledge regarding the population structure of the pest species, whether morphological or genetic, is considered as an essential tool in making effective management decisions. Thus here, we performed the phenotypic characterization of H. armigera populations collected from varied geographic locations across India. Studied populations differed significantly for several external morphometric traits studied at larval, pupal and adult stages. Significant differences were also observed with respect to the intensity of black pigmentation on larval body as well as adult eye and forewing colour patterns. Besides external phenotypic traits, the length of genital organs like aedeagus and valva in males, and bursa copulatrix and bursa seminalis in females also differed significantly amongst populations. The dendrogram based on selected traits showed clear cut differentiation of studied populations into two major groups, one including all the South Zone populations and the other having populations from North and Central Zones. Differences based on phenotyping in the present study indicate the possibility of the existence of different subspecies within the Indian populations of H. armigera.

“…The description of A. mucronota lacks information for most of the characters of the pseudocepalon (Table 2) and most of the available data overlap with those of A. nolazcoae (Table 3, 4). Anastrepha nolazcoae differs from five morphotypes within the A. fraterculus complex (Canal et al 2015(Canal et al , 2018 and A. striata as follows: 1) greater number of oral ridges (16-19; see the dichotomous key in Steck et al 1990), except unknown for Andean and Peruvian morphotypes of A. fraterculus complex; 2) posterior margin of oral ridges fringed in A. nolazcoae, irregularly serrate in A. fraterculus (Brazil-1 and Ecuadorian morphotypes), scalloped or emarginate in A. fraterculus (Mexican morphotype), entire or serrate in A. striata; and 3) approximately 36 accessory plates with fringed posterior margins in A. nolazcoae, apparently seven plates and serrate in A. fraterculus (Ecuadorian morphotypes; see plate 4b in White and Elson-Harris 1992), eight plates and serrate in A. fraterculus (Mexican morphotype), 8-9 plates and entire in A. striata. Anastrepha nolazcoae differs further from the A. fraterculus complex in having a greater number of tubules on the prothoracic spiracle (18-21 vs. 9-18 in fraterculus complex, see Rodriguez et al 2021), although in this character it overlaps with A. striata.…”

Anastrepha is the most diverse and economically important genus of Tephritidae in the American tropics and subtropics. The striking morphology of the third instars of Anastrepha caballeroi Norrbom, Anastrepha crebra Stone, Anastrepha haplacantha Norrbom & Korytkowski, Anastrepha korytkowskii Norrbom, Anastrepha nolazcoae Norrbom & Korytkowski, and three newly discovered and as yet formally unnamed species (Anastrepha sp. Peru-82, Anastrepha sp. nr. protuberans, and Anastrepha sp. Sur-16), and the more typical morphology of Anastrepha aphelocentema Stone, are described using light and scanning electron microscopy. To contribute to a better understanding of the interspecific and intraspecific variation among species in the mucronota species group and facilitate phylogenetic studies, we integrate molecular and morphological techniques to confirm the identity and describe third instars. Larva-adult associations and the identification of described larvae were confirmed using DNA barcodes. We provide diagnostic characters to distinguish larvae among these nine species of the mucronota group and separate them from those of the 29 other Anastrepha species previously described. We introduce the vertical comb-like processes on the oral margin as a novel character, and the unusual character states, including position and shape of the preoral lobe, and dentate or fringed posterior margins of the oral ridges and accessory plates. Our comparative morphology concurs with most previously inferred phylogenetic relationships within the mucronota group.
