First report and population dynamics of the Tobacco Thrips, Thrips parvispinus (Karny) (Thysanoptera: Thripidae) on ridged gourd, Luffa acutangula (L.) Roxy in selected export fields in southern Ghana

Thrips attack several crops causing considerable economic damage. To prevent this damage, sticky traps can be used to monitor their population for the timely execution of management interventions. Ridged gourd or turia (Luffa acutangula (L.) Roxy) is an important Asian vegetable exported regularly to the European Union market from Ghana. However, this vegetable has been intercepted severally at the point of entry because of thrips infestation. The current study is aimed at identifying and monitoring thrips population on turia using blue and yellow sticky traps in six export vegetable production sites in Ghana for two consecutive seasons and three trapping periods. The results showed that Thrips parvispinus (Karny) (Thysanoptera: Thripidae) was the commonest and only species of thrips found attacking turia. The highest and lowest mean number of thrips were recorded from the blue and yellow sticky traps during the dry and the late part of the major rainy seasons, respectively. Thrips population build-up was observed to reach its peak at the flowering stage of the crop. This is the first report of T. parvispinus in Ghana. The implications of this finding on the export of turia to the EU market has been discussed

Hirschsprung Disease in Adults: A Case Report in a Tertiary Hospital in West Africa

Hirschsprung disease in adults is a rare and frequently misdiagnosed cause of long-standing and refractory constipation. Surgical procedures initially developed for pediatric patients are applied to adults with varying degrees of success. A nineteen-year-old girl was diagnosed with Hirschsprung disease in a tertiary hospital of low technology level in Togo. Soave-Boley’s procedure was used as definitive surgical management which resulted in a good outcome
