“…In general, HM contaminated predators produced fewer, larger eggs, with reduced hatching success. One exception was reported by Babczyńska et al [41] who found that funnel web spiders, Agelena labyrinthica (Araneae: Agelinidae), collected from contaminated habitats produced a larger number of eggs, albeit smaller ones, and these eggs exhibited reduced hatching success relative to uncontaminated females.…”

“…HM exposure can influence the probability of mating, fecundity, and egg hatch among natural enemies [38][39][40][41][42][43]. For example, females of the wolf spider, Pirata piraticus (Araneae: Lycosidae), from uncontaminated sites exhibited a decreased probability of copulation when food deprived, whereas females collected from polluted sites did not [43].…”

Urban agriculture is increasing worldwide. A history of contamination within urban landscapes may negatively impact the biota necessary for sustainable crop production, including arthropod natural enemies. This investigation revealed that heavy metal contamination can influence the composition of natural enemy communities and exposure can have reproductive, developmental, immunological and behavioral impacts on predators and parasitoids. Natural enemies exposed to heavy metals typically live shorter lives, take longer to develop and exhibit a reduced reproductive potential. Further, they may incur significant energy costs though the production of detoxification enzymes. This is a new and relatively unexplored area for biological control research, with important implications for our understanding of urban agricultural food web interactions.

“…When spiders are subjected to Cd stress, more energy is expended for defence (i.e., detoxifying the poisonous substance) [31,32,33]. Compared to the control groups, amino acid metabolism (COG, E), carbohydrate metabolism (COG, G), lipid metabolism (COG, I), energy metabolism (COG, C) and digestive system in COG and/or KEGG database were all shown to be significantly enriched, and most of the DEGs were significantly up-regulated, indicating the digestion and metabolism activities were actively induced to maintain the stability of their bodies when subjected to Cd stress.…”

Pardosa pseudoannulata is one of the most common wandering spiders in agricultural fields and a potentially good bioindicator for heavy metal contamination. However, little is known about the mechanisms by which spiders respond to heavy metals at the molecular level. In the present study, high-throughput transcriptome sequencing was employed to characterize the de novo transcriptome of the spiders and to identify differentially expressed genes (DEGs) after cadmium exposure. We obtained 60,489 assembled unigenes, 18,773 of which were annotated in the public databases. A total of 2939 and 2491 DEGs were detected between the libraries of two Cd-treated groups and the control. Functional enrichment analysis revealed that metabolism processes and digestive system function were predominately enriched in response to Cd stress. At the cellular and molecular levels, significantly enriched pathways in lysosomes and phagosomes as well as replication, recombination and repair demonstrated that oxidative damage resulted from Cd exposure. Based on the selected DEGs, certain critical genes involved in defence and detoxification were analysed. These results may elucidate the molecular mechanisms underlying spiders’ responses to heavy metal stress.

“…Meanwhile, phagosome was predominantly enriched both in the groups TL vs. TC (8 DEGs) and TH vs. TC (5 DEGs), which indicated autophagy was probably induced by Cd [30]. When spiders are subjected to Cd stress, more energy is expended for defence (i.e., detoxifying the poisonous substance) [31][32][33]. Compared to the control groups, amino acid metabolism (COG, E), carbohydrate metabolism (COG, G), lipid metabolism (COG, I), energy metabolism (COG, C) and digestive system in COG and/or KEGG database were all shown to be significantly enriched, and most of the DEGs were significantly up-regulated, indicating the digestion and metabolism activities were actively induced to maintain the stability of their bodies when subjected to Cd stress.…”
