“…The concentrations of nickel and copper in leaves of different plants growing in the most polluted sites near the Monchegorck smelter reached 500-800 µg g −1 [17,35]. The earlier experiments demonstrated that 50-200 µg g −1 of copper added to the larval diet decreased the pupal weight of the oriental leafworm moth, Spodoptera litura (F.), to 80% of the control value [39], whereas 100 µg g −1 of nickel did not affect wing size in the cabbage white butterfly, Pieris rapae (L.) [40]. At the same time, the wing length of the autumnal moth Epirrita autumnata (Bkh.)…”

The rapid and selective responses to changes in habitat structure and climate have made butterflies valuable environmental indicators. In this study, we asked whether the decline in butterfly populations near the copper-nickel smelter in Monchegorsk in northwestern Russia is accompanied by phenotypic stress responses to toxic pollutants, expressed as a decrease in body size and an increase in fluctuating asymmetry. We measured the concentrations of nickel and copper, forewing length, and fluctuating asymmetry in two elements of wing patterns in Boloria euphrosyne, Plebejus idas, and Agriades optilete collected 1–65 km from Monchegorsk. Body metal concentrations increased toward the smelter, confirming the local origin of the collected butterflies. The wings of butterflies from the most polluted sites were 5–8% shorter than those in unpolluted localities, suggesting adverse effects of pollution on butterfly fitness due to larval feeding on contaminated plants. However, fluctuating asymmetry averaged across two hindwing spots did not change systematically with pollution, thereby questioning the use of fluctuating asymmetry as an indicator of habitat quality in butterfly conservation projects.

“…Cations such as Ca 2+ , Mg 2+ , Fe 2+ , Cu 2+ , and Zn 2+ are essential components for the appropriate functioning of some enzymes but may be toxic to the insect in high amounts (Lu, Di, & Xueping, ; Zan, Yang, & Wang, ). Huang, Kong, and Seng () demonstrated that low concentrations of metal ions favor the development of Spodoptera litura (Lepidoptera: Noctuidae) in the first larval instars, but a “delayed effect” causes these metals to be harmful in the last instars, leading to a decrease in larval time and increased mortality. Huang et al () also suggest that a concentration of up to 50 mg kg −1 of Cu 2+ in the diet of S. litura favors the development of the caterpillar between the first and third instars.…”

Soybean is one of most consumed and produced grains in the world, and Anticarsia gemmatalis is a pest that causes great damage to this crop due to severe defoliation during its larval phase. Plants have mechanisms that lead to the inhibition of proteases in the intestine of these herbivores, hampering their development. Understanding this complex protease inhibitor is important for pest control. The objective of this study was to evaluate the enzymatic profiles of the intestinal proteases of the soybean caterpillar at different instars. For this, the proteolytic profile of the gut in the third, fourth, and fifth instars were analyzed.Irreversible inhibitors of proteases were separately incubated with A. gemmatalis enzyme extracts at the third, fourth, and fifth instar to assess the contribution of these proteases to total proteolytic activity. The enzymatic extracts were also evaluated with specific substrates to confirm changes in the specific activities of trypsin-like, chymotrypsin-like, and cysteine proteases at different instars. The results showed that the protease profile of A.gemmatalis gut changes throughout its larval development.The activity of cysteine proteases was more intense in the first instar. On the contrary, the serine proteases The protease profile of the gut of A. gemmatalis changes throughout larval development. In the third instar, cysteine protease activity is predominant over others. In the fourth and fifth instars, proteolytic activity is mainly due to serine proteases. This difference in activity in the different instars of A. gemmatalis suggests that the expression of the genes coding for proteases also changes throughout the development of the insect. Using serine PIs is a good strategy for controlling insect pests, as these are the main proteolytic enzymes of Lepidoptera. However, the presence of other important protease subclasses in insect digestibility suggests that a combination of serine and cysteine PIs may be promising, aiming to compromise larval development at different instars.

“…Data are shown in Table (2) indicated that the adult mortality percentage was estimated from 1 to 7 days after treatment to be 13.3and 35.3 % when adult fed on Magnetic Seawater with traces of mixture (2.5g/l) of ferro-salts mixture 1:1, respectively, and increased to 73.3 and 59.3 % in case of treating the adults with the 3 rd group fed on Magnetic Seawater with traces of mixture (50g/L) of ferrosalts mixture 1:1 and match, respectively, (Fig.1,c). Huang et al (2012) demonstrated that lower concentrations of Cu in the diet (25 and 50 mg/kg) shorten the generation time by 4-5 days, while higher concentrations (100 and 200 mg/kg) increased the duration by 1-2 days. Cu, Fe, and Zn are considered as important and essential elements of nutrition for the organisms.…”

In females or male , the longevity was decreased when females were exposed to (compound-2 and 3) , while, this period prolongated when treated with Match. The treatments declined significantly the times of adults longevity to 13.3, 10.0, 8.0 and 18.9 days/ female and 9.6, 7.3, 4.3 and 13.0 days / male, respectively, when the adults of P. gossypiella treated with the different compounds of Sea-water, Seawater +magnetic + traces of mixture 1:1, Seawater +magnetic+ full saturation with mixture 1:1and match (IGR), respectively, compared to 14.5days/ untreated female and 11.3 days/ untreated males.At the same times, the total eggs laid /female and hatchability percentages in adults fed on all treatments were highly significantly affected compared with the untreated adults. These data indicated that the high reduction in eggs laid by females was estimated by 68.57 and 60.73 % with Seawater + magnetic+ full saturation with mixture 1:1 and Seawater + magnetic+ traces of mixture 1:1, against, followed by 46.3% with IGR compared with control.At the same trend, was noticed in hatchability percentages.
