| Abstract | ||
| The present work was carried out to study the effect of infestation type, host plant, moisture content, chemical components and prevailing conditions of temperature and relative humidity as well as natural enemies on the infestation of beetle, Sinoxylon sudanicum Lesne (Coleoptera: Bostrichidae) to nine host plants. Intact branch cuttings were collected from Cassia fistula, Poinciana regia, Cassia renigera, Ficus sycomorus, Morus alba, Mangifera indica, Sailxae gyptiace, Casuarina equisetifolia and Eucalyptus citriodora trees, and transferred to laboratory to study the points of article. The obtained data, reported that the obligatory infestation detected that Cassia fistula attracted the highest number of beetles (7.93 beetles) and gave the highest number of emerged beetles (24.53 beetles), while it showed the lowest duration of generation (50.7days), whereas, Mangifera indica attracted3.13 beetles and gave 9.3 beetles and recorded the longest duration of generation 81.2days. Facultative infestation showed that the highest percentage of infestation (27.2%) recorded for Cassia fistula, while the lowest infestation percentage 6.67% recorded for Morus alba. The suitable moisture content to infestation was varied from 46.45% to 11.61% for Cassia renigera, while the minimum value recorded 7.78% for Cassia fistula. The infestations were decreased with the increasing in phenol content, while duration of generation for beetles increased with increased phenol content. The host plant with high content of carbohydrate (Cassia fistula) infested by highest number of beetles (7.93beetle) and gave the highest number of emerged beetles. S.sudanicum beetle emergence is accompaniment for predator beetle Tarsostenus univittatus (Fam.: Cleridae). | ||
