Variation in fitness of the longhorned beetle, Dectes texanus, as a function of host plant.

In 2007, female beetles were heavier than males among insects collected from sunflower ( F (1,55) = 10.99, P = 0.002) but the difference was only marginally significant for insects collected from soybean ( F (1,61) = 3.93, P = 0.052) and adults of both sexes were significantly heavier when obtained from sunflower (males: F (1,50) = 244.12, P < 0.001; females: F (1,66) = 359.88, P < 0.001).

Sunflower-fed females made more ovipunctures ( F (1,110) = 5.47, P = 0.021) and laid more eggs ( F (1,110) = 4.57, P = 0.035) in sunflower plants than did soybean-fed females, but differences were not quite significant for either number of ovipunctures ( F (1,43) = 2.77, P = 0.103) or number of eggs laid ( F (1,43) = 3.46, P = 0.070) in soybean plants.
