The mean number of follicles, as affected by diet and age (as well as mean length and area of the proximal follicle in each ovariole), was subjected to a 2-way ANOVA and differences determined by Tukey's test (P < 0.05).

Food quality influences ovarian development in Scyphophorus acupunctatus (Coleoptera: Dryophthoridae)

Eggs inside the ovarioles of mature females typically vary in developmental stage and range from very small undeveloped yellow eggs through to large black mature eggs with a thick outer casing (Griffin 2011).

We also examine the egg development within ovariole by dissecting female wasps in PBS at different time intervals after adult emergence (24, 48, 72, and 96 hours).

Developmentally and physiologically distinct phases were examined by dissecting ovarioles from pharate adults 6 d and 10 d after larval-pupal ecdysis in phosphate-buffered saline (PBS; 0.15 mol [1.sup.-1] NaCl, 10 mmol [1.sup.-1] sodium phosphate buffer, pH 7.4).

The females surveyed after treatment with ivermectin and those of the control groups did not show a significant difference in the number of oocytes present per ovariole ([F.sub.3.16]=1.54, p=0.24), either by the size of basal oocytes ([F.sub.3.16]=1.14, p=0.36) or by the presence of an extra-ovarian resorption body ([chi square]=5.43, d.f=3, p=0.14) (Table 2).

Generally only the terminal follicle within an ovariole is vitellogenic, there being a distinct demarcation between the previtellarium and the vitellarium of the ovariole.

Their measurements of tibia and femur length showed higher hybrid than parental species phenotypic values, whereas ovariole number and genital arch area behaved additively.

We measured substantial outward [K.sup.+] and proton gradients at the anterior end of each vitellogenic follicle within an ovariole, Figure 1A.

The total number of mature eggs in each ovary was estimated by multiplying the mean number of developed eggs of 1 ovariole by 7 (total number of ovarioles per ovary).
