“…Interestingly, Zn treatment considerably protected male rats from Cd-induced testicular toxicity, suggesting that the toxic effect of Cd is mediated through the disruption of prenatal Zn metabolism, which is established in mothers during pregnancy [98]. An intriguing study focused on the analyses of the impact of Zn (100, 200, and 400 µg/g of food) on Cd (44 µg/g of food, a sublethal Cd concentration) adapted beet armyworm Spodoptera exigua selected after long-term Cd exposure for 135 generations was performed by Tarnawska et al ( 2019) [99]. The life history traits represented by the duration of L4 and L5 stages, cellular DNA damage, and biochemical parameters (ADP/ATP ratio and ATP and HSP70 concentrations) were determined.…”

Rapid urbanization and industrialization have led to alarming cadmium (Cd) pollution. Cd is a toxic heavy metal without any known physiological function in the organism, leading to severe health threat to the population. Cd has a long half-life (10–30 years) and thus it represents serious concern as it to a great extent accumulates in organs or organelles where it often causes irreversible damage. Moreover, Cd contamination might further lead to certain carcinogenic and non-carcinogenic health risks. Therefore, its negative effect on population health has to be minimalized. As Cd is able to enter the body through the air, water, soil, and food chain one possible way to defend and eliminate Cd toxicities is via dietary supplements that aim to eliminate the adverse effects of Cd to the organism. Naturally occurring bioactive compounds in food or medicinal plants with beneficial, mostly antioxidant, anti-inflammatory, anti-aging, or anti-tumorigenesis impact on the organism, have been described to mitigate the negative effect of various contaminants and pollutants, including Cd. This study summarizes the curative effect of recently studied bioactive substances and mineral elements capable to alleviate the negative impact of Cd on various model systems, supposing that not only the Cd-derived health threat can be reduced, but also prevention and control of Cd toxicity and elimination of Cd contamination can be achieved in the future.

“…Pengendalian terhadap S. exigua oleh petani sampai saat ini masih menggunakan insektisida 2-3 hari sekali, bahkan petani mencampurbeberapa jenis pestisida dalam satu kali aplikasi. (Ahmad, Farid, and Saeed 2018;Tarnawska et al 2019) Teknik ini walaupun mampu menekan serangan S. exigua, tetapi tindakan tersebut tidak bisa dilakukan secara terus menerus karena dapat menyebabkan terjadinya resistensi dan resurgensi hama S. exigua terhadap insektisida dan bisa berdampak buruk terhadap kesehatan manusia dan lingkungan (Wang et al 2018;Nunes et al 2013) Hasil survai Pasaru (1999), menunjukkan bahwa 95% responden yang melakukan pengendalian hama pada tanaman sayuran di Kabupaten Donggala ternyata masih mengandalkan pestisida.…”

This study aimed to determine the effect of fertilizer and mulch on the intensity attack of S. exigua and the yield of Lembah Palu shallot variety. The research was conducted in Bolu Pountu Jaya, Sigi Village, District of Sigi Biromaru, Sigi Regency, from September to November 2013. The study design was a two-factorial randomized pattern with three replicates for each experimental unit. The first factor was various types of mulch consisted of four treatment without mulch (M0), rice straw mulch (M1), cocoa mulch (M2) and plastic mulch (M3). The second factor was different kinds of fertilizers including liquid organic fertilizer (P1), guano fertilizer (P2) and synthetic fertilizer (P3). There is no significant interaction effect between the type of fertilizers and mulch on the intensity of S. exigua and shallot yields. However, the individual effect of the mulches was significant on reducing the intensity of S. exigua attack and increasing the yield of the shallot. The rice straw mulch reduced the attack intensity of S. exigua by 20.83 %, whereas the cacao mulch increased the yield by 47.61 % compared to the control treatment. Keywords : Fertilizer, Lembah Palu shallot, mulch and Spodoptera exigua.

“…Ali et al (2019) reported that Zn (150 µg/g) modulates the tness of S. littoralis larvae. However, Zn also has a protective effect over multiple generations against Cd exposure in Spodoptera exigua (Tarnawska et al 2019). In comparison, iron (Fe) and its toxicity to lepidoptera remains poorly investigated.…”

Metals and herbicides present in the environment affect the vital functions of insect pests, including their development, tolerance, resistance, and survival. Such metal-herbicide interactions will have inevitable, but complicated effects on insects, which remains poorly understood. Here, the interaction of zinc (Zn), iron (Fe), and paraquat (PQ) at subleathal dose on the physiological responses of the Egyptian cotton leafworm Spodoptera littoralis was examined. Co-exposure of Zn/ Fe enhanced the survival of leafworms (10 to 20 mg 100%; 40 mg 85%) compared to separate exposure. Low exposure to Zn/Fe/PQ had the lowest toxicity, possibly because metal complexes have efficient chelating activity, allowing the leafworm to survive longer. Low exposure to Zn, Fe, and Zn/Fe increased food intake and larval weight significantly, and affected frass production. PQ alone hindered feeding, enhanced frass production, and reduced larval weight. In contrast, Zn/Fe and PQ/Zn alleviated toxic effects. Interestingly, Zn/Fe/PQ combined increased larval and pupal weight in surviving individuals. Larval mortality was highest with high doses of PQ (40 mg) and in metal co-exposure diets, with no larvae reaching the pupal stage. Zn/Fe appeared to be essential for the ecdysis of larvae to pupae, with lower larval mortality and extended pupal ecdysis (% days). This study demonstrated the realistic conditions of Zn and Fe interactions with PQ, providing important information regarding physiological toxicity and pest management. Tests on haemolymph-bacteria of S. littoralis using disc diffusion method revealed significant differences with Zn, Zn/Fe, Zn/Fe/PQ, stating their interaction might play a crucial immunomodulatory role in S. littoralis.
