Philippe SIBOMANA
Philippe SIBOMANA is a crop scientist interested in agricultural improvement from field to fork. General areas in his career are mainly Crop protection, plant biotechnology and agricultural surveys. Philippe contributed to the production of improved coffee varieties through tissue culture technique (Somatic embryonesis) as laboratory technician. Those varieties replaced the old coffee trees in Rwanda for quality and yield increment. He also served in producing clean and disease-free banana, flowers, bamboo, passion fruits, pineapples at FAIM Africa. Philippe contributed in Seasonal agriculture survey at National Institute of statistics of Rwanda, where he got a full package in techniques in getting quick and accurate data in terms of agriculture surveys. Philippe worked as Plants and plant products inspector at Rwanda Ministry of Agriculture and Animal Resources(MINAGRI) for plant pest quarantine purpose. Currently, he works as Export Permit Processing Officer at Rwanda Inspectorate, Competition and Consumer Protection Authority (RICA) specifically issuing export certificates to plants, plant products and other articles regulated by National Plant Protection Organization. He obtained a Masters degree in crop sciences from University of Rwanda. Published research article: Nutritional quality of carrot (Daucus carota L.) as influenced by farm yard manure.

presence of aboveground insects. However, there is less evidence to describe the presence of such insects in
Rwanda. Thus, the objective of this study was to assess the abundance of the aboveground insect species in
Musanze district, in the Northern part of Rwanda. Insect traps were laid in agricultural fields ten sectors of
Musanze district; Busogo, Cyuve, Gacaca, Gataraga, Kimonyi, Kinigi,Musanze, Muhoza ,Muko and Nkotsi. The
insects were caught using nets during the day and during night the traps were hung with light to attract insects.
The insects were trapped and collected two consecutive seasons, during the month of April 2021 (wet season) and
July 2021 (dry season). The data were analyzed using SPSS version 24 and Microsoft Excel package. The findings
showed that the overall insect species abundance was as follows; Bush cricket (8.6%), Long-horned grass hoppers
(15.4%), Bombardier beetles (3.4%), Stunk bug beetles (3.1%), Leaf chaffers (3.4%), Leaf beetles (3.7%), Honey
bees (3.6%), Maize leaf hoppers (9.7%), swallowtail butterflies (18.9%), Wasps (2.2%), White butterflies (12.6%),
White flies (9.2) and Leaf miners (6.2%). Hence, the results revealed that there is a significant difference in the
mean amount between insects trapped. The swallowtails butterflies, which are beneficial insects, were highest in
abundance (18.9%) whereas the stung bug beetles was recorded lowest abundance (3.1%). Since the collected
insects included major beneficial insects, during insect pest control, farmers are recommended to firstly use
trapping and netting methods before pesticides application. This can reduce the cost and dangers to human health
and to beneficial insects as well. Besides, they can apply wide spectrum insecticides which have fewer hazards to
the environment.
