Figure 4 in The natural history of the parasitic wasp Trogus pennator (Hymenoptera: Ichneumonidae): Host-finding behaviour and a possible host countermeasure
Figure 4. The average height of plants searched by Trogus pennator (n557 wasps, range58–145 cm) and selected for oviposition by Eurytides marcellus (n541 butterflies, range52–95 cm) was compared in spring 1997. The wasps searched plants significantly taller than those preferred by the female butterflies (P,0.0001, two-tailed t test).
Figure 1. A in The natural history of the parasitic wasp Trogus pennator (Hymenoptera: Ichneumonidae): Host-finding behaviour and a possible host countermeasure
Figure 1. A vegetation survey was conducted in spring 1997 to establish the frequency of Asimina among the broad-leaved plants in the understorey. The mean percentage Asimina was determined at 7.5% by counting stems in 5 m×5 m plots. Plants counted as ''other'' most commonly included Quercus incana, Q. laevis, Vitis rotundifolia Micheaux, V. aestivalis Micheaux, Mimosa, sp., Smilax spp., and several unidentified Compositae. In contrast, 93.3% of plants visited by the wasps were Asimina (P,0.001, chi-square test).
