“…Wing proportions are influenced, according to the size of the rib cage, as individuals with larger wings have more developed muscles (Marden and Chai, 1991). Morphometry studies confirm that the insects' anterior wings have an important allometric measurement in determining size and shape (Di Mare and Corseuil, 2004;Sane, 2003). This fact is called phenotypic plasticity (Gotthard and Nylin, 1995;Loh et al, 2008), and does not justify the great variation only in the wings, but in all the dimensioned segments of this study.…”

“…This arrangement of muscles within the insects' rib cage is directly related to weight, because the larger it is inferred that the male will have better physical conditioning (Srygley and Chai, 1990). Individuals who have these morphometric characteristics exhibit, for example, a higher frequency of copulations, better biological and even physical conditioning (Di Mare and Corseuil, 2004).…”

“…Anterior wings perform the aerodynamic capacity and are closely related to the flight speed. However, the posterior wings function as an airfoil that regulates the direction and maneuverability of the flight (Di Mare and Corseuil, 2004;Dudley, 2000). A. gemmatalis lives in open agroecosystems and travels over long distances, thus requiring a relatively larger wing area (Di Mare and Corseuil, 2004).…”

“…After mounting on the lamina, coverslip and sealed with a thin layer of colorless nail polish dried for two hours. The measurements of the length, width and area of the anterior and posterior wings were obtained with the aid of a stereoscope microscope with an attached camera (Leica S9 i), according to the technique described by Di Mare and Corseuil (2004).…”

Phenotypic plasticity in adults of Anticarsia gemmatalis exposed to sub-doses of Bt-based bioinsecticide

et al. 2024

Anticarsia gemmatalis Hünber, 1818 is one of the main defoliating species in the soybean crop. Bacillus thuringiensis Berliner, 1915, is a bacterium used in the biological control of this pest species. Resistant populations and their sublethal effects caused by the use of the bacteria have already been reported; however, there are no studies on phenotypic plasticity in adulthood exposed to Bt-based bioinsecticide sub-doses. This study aimed to evaluate the morphometry of A. gemmatalis adults under laboratory conditions submitted to the Bt-based bioinsecticide Dipel® over the three generations. The body segments mensuread were width, length, and area of the anterior and posterior wings, the weight of the integument, chest, abdomen, wings, and the whole adult of males and females. Among the treatments, LC5 in the first generation and LC10 in the second generation were those with lower thresholds in relation to the weight of the chest and abdomen, considering the proportions of the body smaller than the females. The female’s weight adulthood was reduced by 10% about males, and, only in the first generation. Males have larger body size and more pronounced phenotypic plasticity than females. Here, we demonstrate the first study assessing the phenotypic plasticity of A. gemmatalis adults.

Background: Climate change has significant implications on ecosystems. We verified the effects of climate change on the malaria vector Anopheles aquasalis using simulated climate change scenarios (SSCCs). Methods: An experimental model was designed for SSCCs, which composed of air-conditioned 25 m 3 rooms. Results: The wing size was significantly different between SSCCs. A colony of Anopheles aquasalis could not be established in extreme scenarios. Conclusions: Increases in temperature and CO 2 in the atmosphere may modify the global epidemiology of malaria, marking its emergence in currently malaria-free areas.

ABSTRACT. Morphometry and mortality in pupae and adults of Brassolis astyra (Nymphalidae, Morphinae). The data presented are based on Brassolis astyra Godart, 1824 individuals sampled randomly in four locations of the State of Rio Grande do Sul, Brazil: Tupanciretã, São Martinho da Serra, Santa Maria -two places. Except in São Martinho da Serra, the data were obtained in urban areas, on Syagrus romanzoffianum palms (Palmaceae). The following parameters were investigated: egg laying number, hatching eggs index, number of miscarried eggs, eggs positioning on the host plant, sex ratio, parasitoid index, emergency pupa-adult frequency, longevity of pupae and adult stages, mass and volume of the pupae and morphometric measurements of pupae and adults' wings. Of eggs collected in Tupanciretã, 46% hatched, 43% had been parasitized and 11% were miscarried. On the other hand, in São Martinho da Serra only 4% of the eggs collected hatched, 95% had been parasitized and 1% were miscarried. In the other localities no eggs were found. Based on adults emerged from the pupae, it was verified that 77% of the males and females presented a normal morphology (viable) and 23% were malformed. The differences in the average values estimated for pupal longevity among the study sites, were statistically significant. The average frequency of adults was 0.47. The data obtained showed a sexual dimorphism in size (weigh) and form (volume) of the pupae. This suggests that the size and the form of the pupae can determine the adults' viability. Such effect could be associated with a stabilizing selection, where would be associated to optima values average of weigh and form. Although the origin of the sampled individuals varied, the parameters that determine the size and shape are in the same direction when comparing the two sexes. Data on longevity and mortality suggest that the estimated values can be influenced by the variability and ecology of the population from which the larvae were sampled.

Os dados analisados são provenientes de indivíduos de Brassolis astyra Godart, 1824 amostrados em quatro localidades do RioGrande do Sul, Brasil: Tupanciretã, São Martinho da Serra, Santa Maria -dois locais. Exceto em São Martinho da Serra, área natural, as demais coletas foram realizadas em áreas urbanas: todas em Syagrus romanzoffianum (Palmaceae). Os parâmetros analisados foram: número de ovos por postura, índice de eclosão de ovos, frequência de parasitoidismo, número de ovos malogrados, posição das posturas na planta hospedeira, proporção sexual, taxa de emergência de pupas e adultos, longevidade das pupas e dos adultos, massa e volume das pupas, e morfometria das pupas e das asas a partir de marcos anatômicos. Dos ovos coletados em Tupanciretã, área urbana, 46% eclodiram, 43% foram parasitados e 11% malograram. Entretanto dos ovos coletados em São Martinho da Serra, área natural, 4% eclodiram, 95% foram parasitados e 1% malograram. Nas demais localidades não fo...
