Alimentary canal and reproductive tract of Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae, Scolytinae) Neotropical Entomology
Rubio G.,José D.; Bustillo P.,Alex E.; Vallejo E.,Luis F.; Acuña Z.,José R.; Benavides M.,Pablo.
The alimentary canal and the reproductive tract of males and females of Hypothenemus hampei Ferrari are described. The alimentary canal of H. hampei showed the crop with several spine-like structures and the midgut with few gastric caeca. We evidenced for the first time that adult females need to feed on coffee in order to produce viable eggs before and during oviposition period. The presence of air bubbles inside the anterior midgut may be due to starvation rather than the response of the environment during flying as previously reported. Two ovaries and the same structures and arrangements common to individuals of the Curculionidae beetles composed the female reproductive system. The male reproductive tract showed a significant difference with respect to...

Natural Enemies and Competitors of Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae) in Colombia Neotropical Entomology
BUSTILLO,ALEX E.; CÁRDENAS,REINALDO; POSADA,FRANCISCO J..
The objective of this research was to survey and record the natural enemies and competitors of the Coffee Berry Borer (CBB) Hypothenemus hampei (Ferrari) in the Colombian coffee region. Despite the recently introduction of CBB to Colombia, 25 natural enemies were recorded, including Beauveria bassiana. Except for this fungus, the other organisms are new records of natural enemies of CBB. This emphasizes the little knowledge about these natural control agents and competitors that can help to keep the CBB population under control. The predators were the group with higher number of natural enemies followed by the competitors, fungi, bacteria and protozoans. Only one parasitoid wasp was recorded attacking CBB adults.
