Influence of garden symphylan (Symphyla: Scutigerellidae) root injury on physiological processes in snap beans
Environmental Entomology 14 (4), 408-412
Abstract: Studies were conducted to determine the effects of garden symphylan, Scutigerella immaculata (Newport), root injury on physiological processes of bush snap beans, Phaseolus vulgaris L. Root injury caused by 10 or 20 symphylans significantly affected physiological processes in snap beans, but plants infested with five symphylans were not significantly different from uninfested plants. Symphylan-induced root injury significantly reduced leaf water potential and increased soluble leaf carbohydrates in plants infested with 10 or 20 symphylans. Photosynthesis, measured as assimilation of ¹⁴CO₂ , also was significantly reduced in plants infested with 10 or 20 symphylans. Total dry weight of shoots and roots of plants infested with 10 or 20 symphylans was significantly reduced 32 days after infestation. Fresh weight of pods was significantly lower in infested plants at harvest 38 days after infestation.
