achieve a similar mortality level of Phthorimaea operculella (Lepidoptera: Gelechiidae) larvae, it was necessary to apply 500 IJ in sandy soil and 2,000 IJ in loam soil of either Steinernema carpocapsae or Heterorhabditis bacteriophora (Hassani-Kakhki et al., 2013). This is important to consider in commercial EPN applications, as an excessive or deficient IJ number applied may increase the costs unnecessarily or result in an inefficient control of the target pest.
In relation to soil texture, this

nematodes were recorded. Treatments were arranged in a completely randomized design (CRD) with three replications and the experiment was conducted three times.
To evaluate the effect of soil texture on fluopyram movement, plastic tubes (6-mm-diam.×160-mm-long) filled with <2.0-mm-diam. sterilized sandy loam soil (62% sand, 30% silt, and 7% clay; <1% organic matter; pH 6.0; CEC 11.3 cmol+/kg) were used in the second experiment. Methods used were the same as described in the first experiment with the

to influence the lipophilicity of the nematode surface coat, auxins and kinetins did not affect spore attachment compared with PBS. Root exudates reduced spore attachment more in sterilized soil than in natural soil. Sterilization may have eliminated microbes that consume root exudates, or altered the chemical components of the soil solution or root exudates. Root exudates caused a greater decrease in spore attachment in loamy sand than in a sandy loam soil. The sandy loam had higher clay content
