Ecology and Field Biology of the Sorghum Chafer, Pachnoda Interrupta (Olivier) (Coleoptera: Scarabaeidae) in Ethiopia
Vol. 5(5), pp. 64-69, August 2013 DOI: 10.5897/JEN2012.0059 ISSN 2006-9855 ©2013 Academic Journals Journal of Entomology and Nematology http://www.academicjournals.org/JEN Full Length Research Paper Ecology and field biology of the sorghum chafer, Pachnoda interrupta (Olivier) (Coleoptera: Scarabaeidae) in Ethiopia Asmare Dejen1* and Yeshitila Merene2 1Wollo University, College of Agriculture, P.O.Box 1145, Dessie, Ethiopia. 2Amhara Regional Agricultural Research Institute, P.O.Box 08 Bahir Dar, Ethiopia. Accepted 4 June 2013 Studies on sorghum chafer (Pachnoda interrupta) were conducted under field conditions for two consecutive years (2005 to 2006) to determine the biology and ecology of the beetle. On average, oviposition rate by a single female was 1.28 eggs per day over a period of 11 days. In general, eggs hatched within 4 to 22 days with a mean of 15.7 days, after which larval and pupal stages lasted a mean of 59.8 and 18.3 days, respectively. The highest rate of oviposition was recorded during the first four days after mating and none after the eleventh day. A total of 156 and 236 sites or samples were investigated from nine habitats (under trees in a forest, under trees in a crop field, in crop fields, border of crop field, grazing land, riverside, manure heaps, termite mound and cattle dung in homesteads) to identify breeding and hibernating areas of the beetles. Fertile humus and moist light soil under the shade of various tree species in the forest and along the riverside were found to be the potential breeding and hibernating areas of the beetles. -
Scarab Beetles in Human Culture
Coleopterists Society Monograph Number 5:85–101. 2006. SCARAB BEETLES IN HUMAN CULTURE BRETT C. RATCLIFFE Systematics Research Collections University of Nebraska Lincoln, NE 68588-0514, U.S.A. [email protected] Abstract The use of scarab beetles (Coleoptera: Scarabaeidae) by primarily pre- and non-industrial peoples throughout the world is reviewed. These uses consist of (1) religion and folklore, (2) folk medicine, (3) food, and (4) regalia and body ornamentation. The use of scarabs in religion or cosmology, once widespread in ancient Egypt, exists only rarely today in other cultures. Scarabs have a minor role in folk medicine today although they may have been more important in the past. The predominant utilization of these beetles today, and probably in the past as well, is as food with emphasis on the larval stage. Lastly, particularly large or brightly colored scarabs (or their parts) are used (mostly in the New World) to adorn the body or as regalia. If one advances confidently in the direction of his dreams and endeavors to live the life which he has imagined, he will meet with a success unexpected in the common hours.—Thoreau This paper is warmly dedicated to Henry Howden in celebration of his many long years of dedicated field work in the Neotropics and the many fine paperson scarab systematics that flowed from his exploration and research. Henry’s illustrious career has added immeasurably to our knowledge of all things scarabaeoid. His students and colleagues have all benefited from his mentoring, advice, and wealth of knowledge.

They are often described as flower pest (“Rose chafers, flower beetles”), and are thought not to be significant as fruit pests. However, during the last ten years some serious damage to fruit has been observed. Since this damage occurs when the fruits are ripening, insecticides cannot be used. There are no literature data about the amount of the damage or how to monitor the damage. This paper describes our monitoring of the population dynamics of the Cetonia aurata and Potosia cuprea, and the method for calculating the damage to fruit suitable for the orchards in this area. The study was conducted during the spring and summer of the year 2005, 2006 and 2007 in the Ravni kotari region, near the villages of Prkos and Smilčić. We used Csalomon® VARb3k funnel traps. -

Zoosystema 35 (4): 537-549. http://dx.doi.org/10.5252/z2013n4a7 ABSTRACT Augosoma centaurus Fabricius, 1775 (Melolonthidae: Dynastinae), one of the largest Scarabaeoid beetles of the Ethiopian Region, is classified in the tribe Dynastini MacLeay, 1819, principally on the basis of morphological characters of the male: large frontal and pronotal horns, and enlargement of fore legs. With the exception of A. centaurus, the 62 species of this tribe belong to ten genera grouped in Oriental plus Australasian and Neotropical regions. We performed cytogenetic studies of A. centaurus and several Asian and Neotropical species of Dynastini, in addition to species belonging to other sub-families of Melolonthidae Leach, 1819 and various tribes of Dynastinae MacLeay, 1819: Oryctini Mulsant, 1842, Phileurini Burmeister, 1842, Pentodontini Mulsant, 1842 and Cyclocephalini Laporte de Castelnau, 1840. The karyotypes of most species were fairly alike, composed of 20 chromosomes, including 18 meta- or sub-metacentric autosomes, one acrocentric or sub-metacentric X-chromosome, and one punctiform Y-chromosome, as that of their presumed common ancestor.
