Plutella xylostella (Linnaeus, 1758), the diamondback moth (DBM), is a well-known and destructive insect pest of brassicaceous crops worldwide. Here, we analyzed the functional responses of four spiders (Araneae) - Ebrechtella tricuspidata (Fabricius, 1775) (Thomisidae), Pardosa laura (Karsch, 1879) (Lycosidae), Pardosa astrigera (Koch, 1878) (Lycosidae), and Pardosa pseudoannulata (Bösenberg & Strand, 1906) (Lycosidae) - on P. xylostella larvae. We also analyzed intraspecific disturbances in the predation reaction and the intensity of scrambling competition of the spiders to... |
