The web quantity and quality of web-weaving spider species Agelena labyrinthica (Clerck, 1757) and Holocnemus pluchei (Scopoli, 1763), were determined depending on the temperature and the amount of food consumed. Two different experiments have been set up in the study. In the first one, spiders were raised at different temperatures (20-25°C and 25-30°C) in laboratory conditions were fed with 10 Drosophila melanogaster (Diptera: Drosophilidae) in each time. In the second one, spiders were fed with 7-10 insects caught from their natural habitats at 20-25°C and 25-30°C. According to this; the amount of food showed statistically significant difference (p<0.05) which consumed by spiders fed with D. melanogaster at 25-30 °C, and it was observed that these spiders weave more frequently and regularly. On the other hand, the webs of A. labyrinthica and H. pluchei were found to be sparse and scarce which fed with D. melanogaster at low temperatures, depending on the amount of food they consumed. As a result, it was determined that the amount and quality of the webs produced by both types of spiders depend on the number of nutrients and high-temperature values (25-30°C).

Nowadays, where the use of biological materials is increasing, the antimicrobial activities of ethanol, methanol, and acetone extracts of silk from the species Agelena labyrinthica (Clerck, 1757) (Agelenidae) and the acetone extract of silk from the species Holocnemus pluchei (Scopoli, 1763) (Pholcidae), which produces insufficient silk, have been studied. Extracts from both spider species were tested against three Gram-negative bacteria (Pseudomonas aeruginosa (ATCC 27,853), Klebsiella pneumonia (ATCC 700,603), and Escherichia coli (ATCC 25,922)), one Gram-positive bacteria (Staphylococcus aureus (ATCC 25,923)), and one yeast (Candida albicans (ATCC 90,028)). It was determined that the inhibition zone diameters created by H. pluchei silk acetone extract against E. coli, P. aeruginosa, and K. pneumonia during 24-h incubation period (14 ± 0.1 mm, 11 ± 0.2 mm, 6.5 ± 0.5 mm, respectively) were greater than those created by A. labyrinthica acetone extract (12 ± 0.2 mm, 7 ± 0.0 mm, 6 ± 0.1 mm, respectively). However, it was found that H. pluchei silk acetone, A. labyrinthica ethanol, and methanol extracts had no antimicrobial activity against S. aureus, but A. labyrinthica silk acetone extract created an inhibition zone diameter of 9.5 ± 0.5 mm. Accordingly, it was determined that the antimicrobial activities of spider silks varied depending on the spider species and the solvent used to obtain the silk extract.
