To quickly assess the difficulty of the text, read a short excerpt:
Experiment, s When mole crickets in petri dishes were buried in the soil and nematodes sprayed on the soil surface, all 14 mole crickets that died at the 4-, 8-, and 10-cm depths contained nematodes (Table 16) . At the 6 cm depth 14 of the 15 mole crickets that died contained nematodes. None of the 3 mole crickets that died in the controls contained nematodes which indicates that the experimental area did not contain naturally-occurring entomogenous nematodes which attack mole crickets. More si...gnificantly, the results showed that when nematodes are applied to the soil surface in the field they can move downward at least 10 cm to kill mole crickets. Moreover, the nematodes found in the mole cricket cadavers were first generation adults. Since it takes 3 days for the nematode to develop from third-stage infectives to 1st generation adults, the third-stage infectives must have moved the 10 cm and infected the mole crickets in only 2 days. 100 Table 15: The number of infective-stage juvenile nematodes recovered from each 2-cm layer of soil 5 days after they were released at point 0.
