Abstract
The present studies focus on the effect of different types of dung mixed with sandy soil on three biological aspects of the pubescent rose chafer, Tmginota squalida Scup. (Coleoptera: Scarabaeidae). Studies were conducted under laboratory conditions of 20.25°C and 60-65% RH. Investigated dung types were: cattle, horse, poultry, their mature compared with separate mud and sandy soils. It was found that, cattle dung was the most attractive to adults followed by horse and dung mixture. The least attractive one was sand. Oviposited eggs in sandy soil did not develop beyond the second Larval instar. Other ones supported development to adult stage. The percentages of survivorship of the larval stage did not differ significantly In the different media types except sandy soil, were it did not exceed 3%. The survivorship of pupal stage ranged between 5.9 and 26.6% with significant differences within dung lopes. Shortestduration of different stages was 93.3 days on poultry dung while it ranged 105.7 to 111.3 days on other tested media. Emerged adults longevity of males and females ranged between 19.7 to 22.6 days and 22.5 to 24.6 days, respectively, with no yielded significant differences within tested dung. Female fecundity was highest for one those developed on horse dung medium. (65.4 eggs/female) and lowest fecundity was recorded in case of using poultry dung medium (54 eggs/female). The effect of adults diet type on longevity and female fecundity can be ranked into three groups. The optimal one is 8. !caber followed by P. males , V. faba and 8. capitata occupied the same rank ,while C sinensiswas the least optimal one. Generally, tested dung in soil is essential for governing insect stages to develop.
