| dc.description.abstract | The two-spotted spider mite, Tetranychus urticae Koch, is one of the most important
pests of strawberry crops in world wide. The use of comparatively resistant cultivars or
varieties may limit the negative effects of this mite. The present studies were compared
to the population growth parameters of T. urticae reared on three strawberry varieties
viz. RU-1, RU-2 and RU-3. The life table parameters were estimated under laboratory
conditions (25 ± 2
0C, 60 ± 10% RH, and a photoperiod of 13:11 h L: D). The average
developmental time in days from egg to female adult on the three varieties were 11.70 ±
1.23 (RU-1), 12.60 ± 0.91 (RU-2) and 12.77 ± 0.92 (RU-3), respectively. The lifetime
fecundities were 57.38 ± 3.67, 56.57 ± 4.42 and 63.90 ± 4.33 eggs/female for RU-1, RU2 and RU-3, respectively. RU-2 was the most suitable host for T. urticae with rm = 0.172
(offspring/female/day), followed by RU-3 (0.170). The slowest population growth was
observed on the RU-1 variety with rm = 0.167. The present findings revealed that RU-1
was less suitable variety, suggesting that if is more registrant to the two-spotted spider
mite compared to the other two varieties. | en_US |
