Fig 1. A parasitoid wasp and 1 of 7 species of predaceous long-legged flies collected in this study. The photograph is insufficient for identification. Although predation events could not be duplicated in captivity, the parasitoid wasp ap- pears to be within a size range that the long-legged fly would attack (e.g., Barrentine 2011). Scale bar = 2 mm.

Hydrilla tip mining midge development is recorded as the proportion of pupae and adults that suc- cessfully developed from the inoculated larvae. Bars are means ± SE. A Wil- coxon means comparison test indicated significance between the control and Btk treatments as indicated by asterisks.

Fig. 6. The 3 in Morphology of the female reproductive system and physiological age-grading of Megamelus scutellaris (Hemiptera: Delphacidae), a biological control agent of water hyacinth
Fig. 6. The 3 parous classes of Megamelus scutellaris. The P1 class (a and b) is characterized by the presence of follicular relics, which may not be present in some or all ovarioles, may be light in coloration and may or may not encircle the base of the ovariole. The follicular relics do not occur at high enough densities to cause an expansion or bulging. The collar may or may not be visible and does not extend past the follicular relic accumulation area. In the P2 class (c and d) follicular relics are present in all ovarioles and at high enough densities to cause bulging. They are distinctly yellow in coloration and relatively darker in comparison to those found in the P1 class. The collar is easily seen and typically extends past the follicular accumulation area. In the P3 class (e and f) follicular relics are variable, may or may not be in high enough densities to cause bulging, and typically completely encircle the base. The collar length easily surpasses the follicular relic accumulation area.

Note the granular appearance of follicular relics having a high enough density to begin to expand or bulge the sides of the lateral oviduct.
