In this perspective, authors studied the biological and physiological effects of LeucokininlI on the growth of Red Palm Weevil through adult insect feeding of the sugar cane treated with different concentrations （0.05%, 0. I%, 0.25%, 0.4%） and biological effects on the number of eggs, the percentage of hatching, the length of the generation and the proportion of deformation, Results showed that there is a significant reduction in the number of eggs laid by the insects as the average number of eggs/female 75.7, 63.5, 59.4, 55.1 egg for each of the concentrations, respectively, compared with the average 140.2 egg in the control group, and reduction of percentages of hatching in all treatment as 71.4%, 64.6%, 70% and 71.5% respectively, compared with 79.3% of the control group. The percentage of deformations in egg densities included 44.4%, 15.4%, 22.6%, 27.8% compared to the control group. The results showed that there are a number of large deformations in the resulting larvae for different treatments. The conclusion is drawn that this study using LeucokininlI confirmed inhibition growth and caused an imbalance in the development stages of different insects due to its effect on the hormones that control molting of insects. This conclusion is furthermore apparent in the larval stage, as it appeared that Leucokininll prevents the insect from completing its life cycle. Test results using LeucokininlI are encouraging, and its future potential use in reducing Red Palm Weevil deserves broader studies.

In males, 0.05% has recorded significant increase in total protein, then 0.25% concentration compeer control, while the maximum high of females 4.846 mg at 0.05% compeer control. The effect of leucokininlI on content of haemolymph cholesterol has shown result that 0.05% concentration and have a clear impact on cholesterol concentration for both sexes with an average reduction of 37.989 mg in males compeer with 120.123 for control, and 57.263 in females compeer with 96.087 mg for control.展开更多
