“…Especially in females, reproductive investment is often limited by the amount of energy reserves that are also used for flight (Elliott & Evenden, 2012;Marden, 2000). Some of the strongest evidence of resource allocation trade-offs involves the allocation of limited resources between flight muscles and fecundity in wing-dimorphic insects: a long-winged morph is flight-capable at the expense of reproduction, while a short-winged morph cannot fly, is less mobile, but has greater reproductive output (Conroy et al, 2018;Devries et al, 2010;Elliott & Evenden, 2012;Guerra, 2011;Hayes et al, 2019;Roff, 1986;Tigreros & Davidowitz, 2019;Zera, 2016;Zera & Denno, 1997). This trade-off occurs as both flight capability and reproduction are energetically costly, and when different traits are each costly, some can be emphasized at the expense of others, and this is an important trade-off in insects (Guerra & Pollack, 2007;Marden, 2000;Roff, 1986;Zera & Brink, 2000).…”

“…Sub-doses of insecticides can alter the development of the wings in insects and other body segments and, therefore, developmental, reproductive and dispersal capacities (Hayes et al, 2019). Thus, it is expected that population interactions and biotic relationships established in a community are in uenced by changes in the individual's morphometry (Vaz et al, 2004;Gorür et al, 2005).…”

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 SC 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 CL10 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.

“…Among them, wing dimorphism functions as an energy trade-off between migration and reproduction as an adaptive switch to environmental changes. Flightless morphs (short-winged or wingless [apterous] morphs) allocate energy into offspring production while winged morphs typically produce fewer offspring but can migrate long distances in search of suitable habitats (1,2). Factors contributing to insect wing dimorphism include population density, microorganisms, temperature, photoperiod, and host quality (1)(2)(3).…”

Ecdysteroids, juvenile hormone, c-Jun NH2-terminal kinases, and insulin/ insulin-like growth factor signaling (IIS) pathways contribute to the regulation of wing dimorphism.…”

Wing dimorphism is a phenomenon of phenotypic plasticity in aphid dispersal. However, the signal transduction for perceiving environmental cues (e.g., crowding) and the regulation mechanism remain elusive. Here, we found that aci-miR-9b was the only down-regulated microRNA (miRNA) in both crowding-induced wing dimorphism and during wing development in the brown citrus aphid Aphis citricidus. We determined a targeted regulatory relationship between aci-miR-9b and an ABC transporter (AcABCG4). Inhibition of aci-miR-9b increased the proportion of winged offspring under normal conditions. Overexpression of aci-miR-9b resulted in decline of the proportion of winged offspring under crowding conditions. In addition, overexpression of aci-miR-9b also resulted in malformed wings during wing development. This role of aci-miR-9b mediating wing dimorphism and development was also confirmed in the pea aphid Acyrthosiphon pisum. The downstream action of aci-miR-9b-AcABCG4 was based on the interaction with the insulin and insulin-like signaling pathway. A model for aphid wing dimorphism and development was demonstrated as the following: maternal aphids experience crowding, which results in the decrease of aci-miR-9b. This is followed by the increase of ABCG4, which then activates the insulin and insulin-like signaling pathway, thereby causing a high proportion of winged offspring. Later, the same cascade, “miR-9b-ABCG4-insulin signaling,” is again involved in wing development. Taken together, our results reveal that a signal transduction cascade mediates both wing dimorphism and development in aphids via miRNA. These findings would be useful in developing potential strategies for blocking the aphid dispersal and reducing viral transmission.
