Abstract

Experiments were conducted in the experimental Farm of Plant Protection Research Institute, Qaha, Qalubiya governorate under field conditions during two successive seasons (2020 and 2021). The aim of this study Sensitivity infestation by Cucurbita fly: Dacus ciliatus Loew (Diptera: Tephritidae) on three different species cucurbits and their control. The results showed that the population fluctuation of the D. ciliatus infesting on three different species cucurbitae (cucumber, zucchini, and snake melon) fruits highly significant differences Whereas F value = F value in first season = 10.15 ** and L.S.D. = 21.11 individuals/240 fruits, could be divided three groups in first season but in the second season could be divided two groups whereas F value in second season = 14.66 *** L.S.D. = 29.24 individuals/240 fruits. The data indicated that the most affected by infestation species was zucchini showed that high abundant of population fluctuation in 12 nd of May in both seasons. In respect to, Zucchini was susceptible 72.21 (larvae stages) / 240 fruits in the first season but in the second season was highly susceptible with 98.63 (larvae stages) / 240 fruits, respectively. The mean susceptibility degree of the two tested seasons showed highly susceptible with 85.42 (larvae stages) / 240 fruits. Zucchini was showed that, D. ciliatus recorded the highest growth rate (4.24), taking time difference 21 days between initial D. ciliatus number 21 and maximum count 110(larvae stages) / 40 fruits in the first season. Data of the second season was showed the D. ciliatus recorded the highest growth rate 6.76 taking 21 day between the initial pest number No (12 (larvae stages) / 40 fruits and maximum count Nt (154 (larvae stages) / 40 fruits. Data showed when using different treatments Penny 9% (Emamectin benzoate 1.5%+Indoxacarb 7.5%), Sinodor WG70% (Imidacloprid 70%) and Betavant SC14.5% (Indoxacarb 14.5%) have a highly significant effect on decreasing D. ciliatus population infesting zucchini growth. The plant extract and nanoparticles treatments have effect on D. ciliatus population whereas decreased mean number of pests the most efficiency method compared to control (without treatment).

瓜蝇对三种瓜蝇的敏感侵染及其防治
试验连续两个季节(2020年和2021年)在Qalubiya省Qaha植物保护研究所实验农场田间条件下进行。目的研究葫芦丝蝇(Dacus ciliatus Loew)对3种不同种类葫芦丝蝇的敏感侵染及其防治。结果表明:3种不同瓜类(黄瓜、西葫芦和蛇瓜)果实上的毛僵螨种群波动差异极显著,第一季F值= 10.15 **,L.S.D. = 21.11个体/240个果实,第一季可分为3组,第二季可分为2组,第二季F值= 14.66 *** L.S.D. = 29.24个体/240个果实。结果表明,受侵染影响最大的是西葫芦,两季中5月12日的种群消长均较高。西葫芦第一季易感虫数为72.21(幼虫级)/ 240个果实,第二季易感虫数为98.63(幼虫级)/ 240个果实。2个试验季节的平均敏感度为高敏感,为85.42(幼虫期)/ 240个果实。结果表明,西葫芦中纤毛虫的生长速率最高(4.24),第一季纤毛虫初数21与最高110(幼虫)/ 40个果实的生长时间相差21 d。第二季数据显示,从初始害虫数(12(幼虫期)/ 40个果实到最大害虫数(154(幼虫期)/ 40个果实之间的21 d内,纤毛虫的生长速度最高,为6.76;结果表明,Penny 9%(苯甲酸埃维菌素1.5%+茚虫威7.5%)、Sinodor WG70%(吡虫啉70%)和Betavant SC14.5%(茚虫威14.5%)处理对西葫芦毛螨的抑制效果极显著。植物提取物和纳米颗粒处理对毛缕螨种群有一定的影响,而减少毛缕螨的平均害虫数量的方法与对照(不处理)相比效果最好。
