“…Working with Coccinella septempunctata L., Wu et al (2015) found that complete regeneration was achieved by over 80% of individuals when complete ablation of a leg occurred in the second instar, with a declining proportion of individuals regenerating the leg completely when ablation occurred in subsequent instars; only about 38% of individuals regenerated legs ablated in the fourth instar, but it was not clear if these data included partially as well as fully regenerated individuals. Saxena et al (2016) examined Menochilus sexmaculatus (Cheilomenes sexmaculata) (Fabricius) and found that only 32% of individuals fully regenerated limbs when they were severed proximal to the coxa in the fourth instar, and that the proportion regenerating was lower when ablation was conducted in the third instar. In contrast, Wang et al (2015), working with a Chinese population of H. axyridis, observed 83% survival of larvae subjected to foreleg amputation in the fourth instar, with 75% of individuals regenerating the leg.…”

“…The recent discovery that many species of Coccinellidae possess varying levels of limb regeneration ability during pupation (Wang et al, 2015;Wu et al, 2015;Saxena et al, 2016) has raised various questions about the biological and ecological significance of limb regeneration within the family. If limb regeneration evolves in response to natural selection, we might expect its adaptive value to vary among ecological contexts.…”

Previous work revealed that Harmonia axyridisPallas (Coleoptera: Coccinellidae) in Beijing, China, were capable of regenerating a forelimb amputated in the fourth instar; 75% of surviving individuals fully regenerated the limb during pupation. In this study, we tested a population of H. axyridis invasive in North America and found that virtually 100% of beetles surviving the operation successfully regenerated the limb. Ablated/regenerated beetles spent longer in pupation, and emerging females were smaller than controls. However, reproductive success was unaffected in all pairwise crosses of control/regenerated adults; there were no differences in pre‐oviposition period, the time required to produce 10 clutches, 10‐day fecundity, or the fertility of eggs, whereas ablated/regenerated parents paid a developmental cost, their progeny obtained benefits. Offspring of crosses that included a regenerated parent tended to have faster larval development than the control cross, although not all were significantly different from controls. However, when either or both parents were ablated and regenerated, their daughters were heavier than controls at emergence. Limb regeneration during pupation appears to activate a physiological cascade which increases the magnitude of beneficial parental effects normally conferred to progeny, possibly via pleiotropic effects. The invasive North American H. axyridis population appears to have higher regeneration capacity than the Chinese population tested previously, although how regeneration capacity might be associated with invasiveness remains unclear. Limb regeneration ability may be a side effect of selection on other traits that confer high fitness under either natural or sexual selection, as it seems unlikely to confer fitness benefits directly in this species.

“…Leg regeneration in insects has been studied in at least 36 genera of 11 orders, including Blattaria, Periplaneta americana [10], Leucophaea maderae [11], Eupolyphaga sinensis Walker [12], Phasmida, Sinophasma spp. [13], Orthoptera, Acheta domestica [14], Lepidoptera, Galleria mellonella [15], Odonata, Ischnura cervula [16], Dictyoptera, Blattella germanica [17], Triatominae, Rhodnius prolixus [18], Heteroptera, Oncopeltus fasciatus [19], Coleoptera [20,21,22], Tribolium castaneum [23]. Numerous studies associated with regeneration are also reported in hemimetabolous insects such as cockroaches [24,25] and crickets [26,27].…”

Developmental cost of leg-regenerated Coccinella septempunctata (Coleoptera: Coccinellidae)

As larval cannibalism is common under intensive rearing conditions, leg regeneration can help ladybugs adapt to the competitive environment, but whether the leg regeneration leads to side effects on development remains unclear. To analyze the potentially developmental cost of leg regeneration, the developmental period and weight of leg-regenerated Coccinella septempunctata were studied in the laboratory. The results showed that, when the time intervals between the emergency of 4th-instar larva and leg amputation increased, the developmental period of leg-regenerated 4th-instar larvae was gradually prolonged. Significantly developmental delay were also examined at prepupal and pupal stages, and various timings of leg amputation affected the periods of leg-regenerated prepupae/pupae similarly. After the leg was amputated at different larval instars, the developmental delay only occurred at the larval instar when the leg was amputated, whereas other larval instars failed to be extended, and the developmental periods of leg-regenerated prepupae/pupae were affected similarly by the instars of leg amputation. Developmental delays possibly resulted in more consumption by leg-regenerated larvae, and then weight gains at prepupal/pupal stages, but different larval instars of leg amputation affected the weight gain similarly. Both the developmental delay (at 4th-instar larval, prepupal and pupal stages) and weight gain (at pupal and adult stages) in complete/bilateral amputation were longer or greater than those in half/unilateral amputation. However, the thoracic locations of leg amputation impacted the developmental delay and weight gain similarly. Our study indicates that although leg regeneration triggers the developmental cost decreasing the competitive superiority or agility, C. septempunctata larvae still choose to completely regenerate the leg to adapt to complex environments. Thus, in order to remain competitive at adult stages, leg-impaired larvae may make an investment tradeoff between leg regeneration and developmental cost.
