“…Although variability in individual responses was high and not always significant, aversion increased with increasing ZnSO 4 in the diet. These results are consistent with the results obtained by Sell & Bodznick (1971) for Heliothis virescens Fabricius (Lepidoptera: Noctuidae), which was deterred by concentrations ‡0.2% ZnSO 4 , and Spodoptera littoralis Boisduval (Lepidoptera: Noctuidae), which was deterred by concentrations ‡0.1 M ZnSO 4 (Salama & El-Sharaby, 1972). Similarly, Pollard & Baker (1997) demonstrated significant preference of Schistocerca gregaria (Forskål) (Orthoptera: Acrididae) and Pieris brassicae (L.) (Lepidoptera: Pieridae) for low Zn treatments over high Zn treatments in choice experiments.…”

In toxicology studies, the use of death as an endpoint often fails to capture the effects a pollutant has on disruptions of ecosystem services by changing an animal's behavior. Many toxicants can cause population extinctions of insect species at concentrations well below the EC 25 , EC 50 , or EC 90 concentrations traditionally reported from short-term bioassays. A surprising number of species cannot detect metal and metalloid contamination, and do not always avoid food with significant metal concentrations. This frequently leads to modified ingestion, locomotor, and reproductive behaviors. For example, some species show a tendency to increase locomotor behaviors to escape from locations with elevated metal pollution, whereas other insects greatly decrease all movements unrelated to feeding. Still others exhibit behaviors resulting in increased susceptibility to predation, including a positive phototaxis causing immatures to move to exposed positions. For purposes of reproduction, the inability to avoid even moderately polluted sites when ovipositing can lead to egg loss and reduced fitness of offspring. Ultimately, impaired behaviors result in a general reduction in population sizes and species diversity at contaminated sites, the exceptions being those species tolerating contamination that become dominant. Regardless, ecosystem services, such as herbivory, detritus reduction, or food production for higher trophic levels, are disrupted. This review evaluates the effects of metal and metalloid pollution on insect behaviors in both terrestrial and aquatic systems reported in a diverse literature scattered across many scientific disciplines. Behaviors are grouped by ingestion, taxis, and oviposition. We conclude that understanding how insect behavior is modified is necessary to assess the full scope and importance of metal and metalloid contamination.

“…However, by comparing the growth of larvae fed with high‐ and low‐zinc leaves (∼1,700 and ∼120 μg/g dry wt, respectively, in experiment 2) of V. calaminaria , it appears that a high‐zinc diet slows down insect growth and protracts the duration of the larval period by approximately 2 d (+18%). This is in agreement with previous data showing that a delayed growth generally is observed in Lepidoptera larvae fed with artificial diets enriched with zinc [11,13–15] or with other metals, such as cadmium, copper, and lead [10,13,14]. Metals have toxic effects by entering into biochemical reactions in which they are not normally involved [10], and larvae feeding on high‐metal diets probably need more energy for metal‐detoxication processes [15].…”

“…Zinc is an essential trace element for terrestrial invertebrates [10]. However, high-zinc diets slow down the growth of Lepidoptera larvae and often decrease pupal mass [10][11][12][13][14][15]. Metals are known to disturb protein synthesis [16], carbohydrate content [17], and lipid content [18] and to increase respiration rate [15].…”

Abstract-The larvae of Issoria lathonia L. feed in natural conditions on several Viola spp., among which are the zinc-accumulating Viola calaminaria (Gingins) Lej. and the nonmetal-accumulating Viola tricolor L. To examine how I. lathonia caterpillars cope with the naturally high foliar zinc concentration of V. calaminaria, we compared the growth of caterpillars reared on leaves varying in zinc concentration. Larvae were fed in controlled conditions with V. calaminaria and V. tricolor grown on noncontaminated soil (i.e., two low-Zn diets) and with V. calaminaria grown on zinc-enriched soil (i.e., one high-Zn diet). Larvae had a higher growth rate when fed with noncontaminated V. calaminaria compared to zinc-enriched V. calaminaria, suggesting that zinc slows down larval growth. However, larvae consumed more leaves of zinc-enriched V. calaminaria (ϩ45%; estimated from fecal mass) compared with noncontaminated V. calaminaria, suggesting that zinc accumulation would not be advantageous to plants. Caterpillars reared on high-zinc leaves regulate their internal zinc concentration through excretion of highly metal-concentrated feces. When kinetics of growth on both low-zinc diets were compared, it appeared that larval development was faster on noncontaminated V. calaminaria than on V. tricolor. This suggests that more nutrients or less feeding inhibitors in V. calaminaria account for fastest growth. Developmental rates on V. tricolor and on zinc-enriched V. calaminaria were similar, despite the high leaf zinc concentration of the latter species. Together with the abundance of V. calaminaria on calamine soils, this may explain why the largest populations of I. lathonia develop on V. calaminaria in Belgium.

“…), milho 'Antigua' e sorgo sobre a alimentação de lagartas de Spodoptera frugiperda (J. E. Smith): verificaram que todos os sais, utilizados afetaram adversamente a preferência para a alimentação das lagartas nesses três hospedeiros. SELL & BODZNICK (14) constataram que a adição de zinco, através de baixos níveis de ZnSCU, em dieta para Heliothis virescens (Fabricius), inibiu a pupação, além de interferir negativamente no desenvolvimento larval. WISEMAN et alii (16) observaram que, em milho, a aplicação de zinco proporcionou uma redução no peso de lagartas de S. frugiperda.…”

Efeito da calagem e da adubação potássica sobre a área foliar de soja consumida por lagartas das folhas

Na Estação Experimental de Mococa (SP), foi estudado o comportamento do cultivar de soja IAC-9, submetido a cinco níveis de adubação potássica e três de calagem, em relação a área foliar comida por lagartas. Houve infestação natural de lagartas no campo experimental, sendo que a espécie predominante foi Anticarsia gemmatalis (Hubner) (Lepidoptera: Noctuidae). Foram coletadas folhas do topo e da parte mediana das plantas para a avaliação visual da porcentagem de área foliar comida e para posterior análise de teores de macro e micro-nutrientes. Verificou-se que as lagartas apresentaram preferência significativa para se alimentar de plantas das parcelas com calcário em comparação com as plantas das parcelas sem o corretivo. Não se observou influência da adubação potássica na alimentação das lagartas.
