ABSTRACT

Typhlodromus transvaalensis is a generalist predatory mite with economic potential to control eriophyid mites in various fruit trees. Developmental times were significantly longer on Aculus fockeui and Calepitrimerus baileyi than on Aceria dioscoridis. Females of T. transvaalensis presented the shortest oviposition period (20.39 days) and adult longevity (28.96 days) on C. baileyi, while having the longest periods on A. dioscoridis (29.77 and 36.17 days). Total fecundity of females offered A. dioscoridis (39.90 eggs/female) was highest, followed by A. fockeui (27.12 eggs/female) and was lowest on C. baileyi (23.26 eggs/female). The intrinsic rates of increase (r) were higher on A. dioscoridis (0.225 females/female/day) than on A. fockeui (0.175 females/female/day) and C. baileyi (0.168 females/female/day). The generation time (T) was statistically similar on A. fockeui (17.788 days) and C. baileyi (17.501 days) and longest, while was shortest on A. dioscoridis (15.711 days). The net reproductive rate (R0) and the gross reproductive rate (GRR) were highest on A. dioscoridis (34.457 eggs/individual and 35.390 eggs/individual), whereas the lowest values were obtained on C. baileyi (19.107 eggs/individual and 19.500 eggs/individual). The results suggest that T. transvaalensis is a promising control agent for A. fockeui and C. baileyi on pear and apple trees.

摘要

Typhlodromus transvaalensis是一种多面手捕食螨,具有控制各种果树中的螨类的经济潜力。发展时间分别显著再上刺瘿fockeuiCalepitrimerus鼢鼠螨dioscoridisT. transvaalensis的雌性在C.baieyi上表现出最短的产卵期(20.39天)和成虫寿命(28.96天),而在A. dioscoridis上的产卵期最长(29.77和36.17天)。提供A. dioscoridis (39.90 个卵/雌性)的雌性总繁殖力最高,其次是A. fockeui(27.12 个鸡蛋/雌性)并且在 C.baieyi 上最低(23.26 个鸡蛋/雌性)。增长(R)的特性率较高A. dioscoridis(女0.225 /女性/天)比A. fockeui(女0.175 /女性/天)和C.贝氏(女0.168 /女性/天)。A. fockeui (17.788 天) 和C. Baieyi (17.501 天)的世代时间 (T) 在统计上相似,最长,而A. dioscoridis (15.711 天)最短。净生殖率(R0)和总的繁殖率(GRR)为最高上A. dioscoridis(34.457个卵/个体和35.390鸡蛋/个体),而在获得的最低值C.鼢鼠(19.107 个鸡蛋/个人和 19.500 个鸡蛋/个人)。结果表明,T. transvaalensis是梨树和苹果树上的A. fockeuiC. Baileyi的有前途的控制剂。
