| Abstract/Contents: | "The susceptibility of Tipula paludosa and Tipula oleracea larvae to Steinernema feltiae was examinated in laboratory bioassays. Dauer juveniles (DJs) entered the larval hemocoel mainly by direct penetration of the cuticle. All instars except L1 encapsulated nematodes in the hemocoel. However, the prevention of larval death by encapsulation was dependent on the number of invading nematodes. Larval mortality was correlated with the number of invading nematodes, indicating that DJ penetration is the limiting step during pathogenesis. In contrast to other instars, the dosage-mortality response of young L1 was less pronounced. T. paludosa was less susceptible to S. feltiae than T. oleracea. In both Tipula species highest mortality was recorded for the L1 approaching the first molt, while young L1 were less susceptible. Susceptibility of L2 to L4 larvae decreased with their age. For T. oleracea, LC₅₀ values ranged from 7 DJs per insect for the L1 approaching the first molt, to 56 for the L4. CO₂ release of the different larval stages was not correlated to nematode invasion. It is therefore concluded that penetration is not triggered by CO₂, but by other more specific stimuli." |
