The design was completely randomized with fifteen repetitions and the following biological parameters were assessed: duration of the nymphal
period and of the pre-oviposition period, longevity of adults, percentage of fertile females; total number of eggs per female, number of eggs per egg laying and interval between egg laying.
We surveyed parks twice, with a minimum of 2 weeks separation, during the nymphal
activity peak (15) of May 30-June 30, 2017 (Table 1).
carnea was estimated using 5 different aphid densities (4, 8, 16, 32, and 64) of mixed nymphal
stages, over a 5-d period.

(1st, 2nd, 3rd, 4th, and 5th instar) stages and development cycle (egg-adult) of Neopamera bilobata fed unripe strawberry fruits of the cultivar Aromas at the temperatures of 16, 19, 22, 25, 28, or 30 [+ or -] 1[degrees]C (70 [+ or -] 10% RH; 12h photophase).
Leafy wooded areas and grassy meadows are the preferred habitats for blacklegged deer ticks and American dog ticks, which both spend their larval stage in leaf litter, their nymphal
stage on small animals, and their adult stage in tall grass or other shrubby vegetation.
In order to confirm the nymphal
series with a known adult, eleven 5th instar nymphs were collected on 9 July 2015, at WDSWA and placed in a fine mesh butterfly rearing cage with a supply of fourwing saltbush.
radiata was determine by conducting choice test with 5 replication between susceptible nymphal
stages in the previous experiment the combination of the choice test are 3rd and 4th instars nymphs3rd and 5th instars nymph and 4th and 5th instars nymphs.
Thus, the aim of this work was to assess the number of juvenile instars and duration of nymphal
development of C.
Data recorded from duration of incubation period, duration of the nymphal
period, duration from egg to adult, and longevity of adults were transformed in [(x + 0.5).sup.l/2], and data recorded from nymphal
viability in arcsine [(x + 0.5/100).sup.1/2] for normalization and then were subjected to the one-way ANOVA.
Adult and nymphal
cixiids were sampled by hand, aspirator, and sweep net in the wetland around Headquarters Lake, Soldotna, Alaska (N 60[degrees]27'35" W 151[degrees]03,58,i), at least weekly from May 28, when soils in the muskeg were still partly frozen, until the first fall frost on September 20, 2013.
