Other claims from this paper (9)
- Association Hopper within-plant distribution was more closely associated with vegetative development in 1986 than 1987.
- Observation The most likely mainstem node held at least 50% of nymphs through 4 July at V6–V7.
- Observation The most likely mainstem node held at least 30% of nymphs through 10 August at Vl3–V18.
- Observation All nymphs occurred on the mainstem, mainstem petioles or first lateral branch node from emergence to first bloom.
- Observation From R1 to season end, significantly more nymphs occurred on mainstem petioles.
- Observation Twice as many nymphs were associated with lateral branches as with the mainstem after R1.
- Observation Nymph density and proportion of infested soybean plants were greater in 1986 than 1987.
- Method / resource Individual plant samples indicated greater nymph aggregation than larger sampling units such as ground cloth.
- Method / resource Regression estimates of Taylor's coefficients supported sequential enumerative and presence-absence sampling plans.
