# A Preliminary Analysis on the Insecticidal Effect of Cyantraniliprole against Stored-Product Pests
## 3 Results  
All tested doses of cyantaniliprole were effective against beetle adults, with variation in virulence. As expected, the mortality percentage depended on the dose of cyantanilip-role. The final mortality percentages of _T. molitor_ adults, which were recorded on day 28 after exposure, ranged from 13.3% (250 ppm) to 93.3% (3000 ppm) in the treatments with cyantaniliprole (F = 3.181, df = 36.996, \(p<0.001\)) (Figure 1). The final mortality percentages of _T. confusum_ adults ranged from 33.3% (250 ppm) to 100% (3000 ppm) (F = 5.226, df = 36.996, \(p<0.001\)) (Figure 2). The medial survival time of tested adults after exposure to cyantaniliprole was dose-dependent. On the other hand, the medial survival time of control adults was longer in comparison to the medial survival time of adults that had been sprayed with cyantaniliprole. More specifically, the medial survival time of _T. molitor_ adults, after treatment with different doses of cyantaniliprole, ranged from 26.7 (250 ppm) to 13.4 days (3000 ppm) (F = 5.887, df = 9, \(p=0.034\)) (Table 1); for _T. confusum_ adults, it ranged from 24.3 (250 ppm) to 7.7 days (3000 ppm) (F = 2.113, df = 9, \(p<0.001\)) (Table 1). Control mortality was low for _T. molitor_ adults, with a high median survival time (28 days). Control mortality of _T. confusum_ with a high median survival time was 27.3 days (Table 1).

The final mortality percentages of _A. dioperinus_ adults, which were recorded on day 28 after exposure, ranged from 26.6% (250 ppm) to 93.3% (3000 ppm) in the treatments with cyantrainiliprole (F = 4.112, df = 36.996, \(p<\) 0.001) (Figure 3). The final mortality percentages of _R. domestica_ adults ranged from 16.6% (250 ppm) to 86.6% (3000 ppm) (F = 5.222, df = 36.996, \(p<\) 0.001) (Figure 4). Finally, the final mortality percentages of _T. granarium_ adults ranged from 26.6% (250 ppm) to 80% (3000 ppm) (F = 3.911, df = 36.996, \(p<\) 0.001) (Figure 5). Moreover, the medial survival time of _A. diaperinus_ adults, after treatment with different doses of cyantrainiliprole, ranged from to 9.9 days (3000 ppm) to 22.9 days (250 ppm) (F = 7.124, df = 9, \(p=\) 0.032) (Table 1). For _R. domestica_ adults, it ranged from 10.7 days (3000 ppm) to 25.3 days (250 ppm) (F = 5.195, df = 9, \(p<\) 0.001) (Table 1). Lastly, for _T. granarium_, the median survival time ranged from 12.2 days (3000 ppm) to 24.2 days (250 ppm) (F = 6.669, df = 9, \(p=\) 0.025) (Table 1). Control mortality was low for _A. diaperinus_ adults, with a long median survival time (26.9 days). Finally, the control mortality of _R. domestica_ and _T. granarium_ was minimal, with a long median survival time of 27.3 days.

The results of LC50 values of the tested adults are shown in Table 2. The estimated LC50 values were lower for _T. confusum_ compared with the other species, indicating higher virulence of cyanraniliprole against _T. confusum_. Furthermore, _R. dominica_ and _T. molitor_ adults were more tolerant of cyanraniliprole.
