However, it is less likely to benefit crops such as sunflower and cotton that have been shown to be as attractive to ovipositing females.
But it might conceivably be inhabited by sunflowers with sufficiently precise mirrors to concentrate sunlight by a factor of 108.
Two zones were identified with a specific esterasic activity only in the shielded sunflower plants.
For each major crop (maize, soybean, sweetcorn, sorghum and sunflower) three random sites were visited weekly.
The sunflower, lily and peacock feather therefore distanced their user from the world of feminine frills.
Similar but less dramatic results were also evident for sunflower.
The number of "sunflower petals" indicates the number of cases represented at that data point.
In between are six crop specific papers; one on maize, sunflower and soybean, two on soybean, then one each on maize, cassava and rubber.
