“…This species comprises seven subspecies, and several forms share the same hosts, that is Brassica species (Liu, ; Pease, ). The larvae of A. monuste feed on leaves throughout their entire development phase, causing substantial damage to crops (Liu, ; Santana, Zago, & Zucoloto, ). The adults can then migrate over long distances in search of oviposition sites (Barros‐Bellanda & Zucoloto, ; Hayward, ; Poffo et al, ) and oviposit on leaves in clusters of varying sizes from one to 144 eggs (Santana, Rodrigues, & Zucoloto, ).…”

The butterfly Ascia monuste L. (Lepidoptera: Pieridae) is a specialist pest of brassica crops in neotropical regions where it significantly impacts crop production. Understanding the actual and potential distribution of the pest and its hosts in current and future climates may help government agencies to mitigate and manage potential incursions. Here, we use MaxEnt algorithm to model the current distribution of both A. monuste and its host, Brassica oleracea var. capitata L. (cabbage) and then model the likely impact of projected climate change (RCP 4.5 and 8.5 scenarios) on their potential future distributions. While A. monuste is currently restricted to the American continent, we show that under current conditions the potential distribution of both the butterfly and cabbage includes areas of Africa, Asia, Oceania and Europe to some extent. The annual temperature range and mean annual temperature were the strongest predictors of the distribution of both species. Under a projected climate change scenario, suitable areas in the tropical climate zone are expected to decrease for both species. However, in temperate regions, the suitable area for cabbage is expected to increase but will remain unsuitable for the pest. Our results highlight the need for strategies to prevent the introduction of A. monuste to other areas of the tropical climate zone and for the development of management practices in the neotropical region.

“…On the other hand, there is evidence that cannibalism has a negative impact on insect fitness. For instance, in larvae of the lepidopteran Spodoptera frugiperda , cannibalism reduces survival and pupal weight [ 22 ], and larval cannibalism in the lepidopteran Ascia monuste orseis produces smaller adults [ 23 ]. Considering the contrasting evidence, it is possible that cannibalism may have positive or negative effects, depending on the species involved and the environmental conditions.…”

Cannibalism is known in many insect species, yet its impact on insect metabolism has not been investigated in detail. This study assessed the effects of cannibalism on the metabolism of fourth-instar larvae of the non-predatory insect Helicoverpa armigera (Lepidotera: Noctuidea). Two groups of larvae were analyzed: one group fed with fourth-instar larvae of H. armigera (cannibal), the other group fed with an artificial plant diet. Water-soluble small organic compounds present in the larvae were analyzed using two-dimensional nuclear magnetic resonance (NMR) and principal component analysis (PCA). Cannibalism negatively affected larval growth. PCA of NMR spectra showed that the metabolic profiles of cannibal and herbivore larvae were statistically different with monomeric sugars, fatty acid- and amino acid-related metabolites as the most variable compounds. Quantitation of 1H-13C HSQC (Heteronuclear Single Quantum Coherence) signals revealed that the concentrations of glucose, glucono-1,5-lactone, glycerol phosphate, glutamine, glycine, leucine, isoleucine, lysine, ornithine, proline, threonine and valine were higher in the herbivore larvae.

“…However, the decision-making process of herbivorous insects regarding the feeding on a variety of food sources and the switching of hosts, either between or within host plants, is influenced by the costs and benefits associated with such behavior [13]. For instance, the behavioral and physiological adjustments of herbivorous insects to their original host can influence their successful adaptation to and utilization of new hosts, which, in turn, impacts their development and reproductive success [21][22][23]. At the same time, herbivorous insects are constrained by biological factors such as predation risk, competition, or parasitism during host switching, thereby reducing the possibility of host switching between larvae and adults [24].…”

Both larvae and adults of the Henosepilachna vigintioctopunctata feed on leaves of potatoes, tomatoes, and eggplants. Given the variation in planting times of host plants in the Jianghan Plain, host switching between larvae and adults of H. vigintioctopunctata is inevitable to ensure continuous food availability. We evaluated the effect of consistent versus diverse larval and adult host plant feeding experience on growth performance, fecundity, longevity, and feeding preferences of H. vigintioctopunctata through match-mismatch experiments. Host plant quality significantly influences larval development and adult reproduction. Potatoes are identified as the optimal host plant for H. vigintioctopunctata, whereas eggplants significantly negatively affect the adult fecundity. Adult stage host feeding experience determines the fecundity of H. vigintioctopunctata, irrespective of the larval feeding experience. The fecundity of H. vigintioctopunctata adults on eggplant leaves remains significantly lower than that observed on potato leaves. Similarly, adult H. vigintioctopunctata demonstrate a preference for consuming potato leaves, irrespective of the larval feeding experience. Although host switching between larval and adult stages offers lesser benefits for the performance of herbivorous insects compared to a consistent diet with potato leaves, it maintains H. vigintioctopunctata population continuity amidst shortages of high-quality potato hosts.
