These results suggest that unmown ground cover helps conserve ground spiders by decreasing the number of spray droplets reaching the ground surface.īates D, Maechler M, Bolker B, Walker S, Christensen RHB, Singmann H, Dai B, Scheipl F, Grothendieck G, Green P, Fox J (2020) Package ‘lme4’. Also, the number of spiders in the traps under unmown ground cover was not decreased by insecticide spraying, whereas spraying significantly decreased the number under mown ground cover. As a result, with unmown ground cover, the proportion of ground surface wetted by the spray droplets was small. Also, we set up four treatments (with and without ground cover mowing and insecticide spraying) and compared the numbers of spiders trapped by pitfall traps. We compared the proportions of the ground surface wetted by spray droplets among four ground cover conditions. Here, we showed that unmown ground cover mitigated the negative effects of insecticide on ground spiders by shielding them from sprayed insecticide droplets. Several studies have shown that spiders prey on pests and contribute to pest density control in apple orchards, making it important to develop orchard management methods that reduce the negative effects of chemical disturbances on such spiders. With so much to find out, the study of spiders is a rewarding field for both professional and amateur researchers.In agroecosystems, natural enemies are important for sustainable agricultural production. We need to gather more information about how Australian spiders live - their behaviour, ecology and life histories. There is much more collecting, observational and descriptive work to be done on Australia's spider fauna.
