Control the larval and pupal stages of Meat Fly Sarcophaga haemorrhoidalis (Fallen) (Sarcophagidae: Diptera) by using the phenolic and alkaloids extracts of Citrullus colocynthis

Abstract

This study done to evaluate the efficiency of alkaloids and Phenolic extracts of Citrullus colocynthis to control the larvae and Pupae stages of meat fly Sarcophaga haemorrhoidalis .Results revealed the surpass of phenols of C. colocynthis on the extracts of alkaloids insect and by the average reached to 40.7% opposite to 31.06% of the phenolic, The phenolic extracts give mortality rates reached 90% , 70% and 66.6% for the 1st , 2nd and 3rd instars on the concentration 50% , while they for the occurrence high percentage of mortality for larval stage of this reached to 70% , 56.6% and 50% for the larval three instars on alkaloids extracts on the same concentration . The first larval stage much effected by the extracts with mortality medium reached to 48.8% by treating the phenolic and 40% for alkaloids extracts, there after the second and the third stage respectively.Also results pupa with light weight relatively, The phenolic extracts was apparently in surpass concerned the great effect of the usage of extracts on pupal stages of this inset dead pupa and some morphological deformed pupa, also product over alkaloids in this effect and with average weight reached to 1.43 gm for 20 pupa where as alkaloids extract with 1.68 gm.
