MITCHELL [1924, 2], using young growing rats as experimental animals, found that the biological value of proteins was lessened as the proportion of the protein in the diet was increased. He considered that this result might in part be due to the fact that proteins could be used more economically for maintenance than for growth. When supplied in the diet in a low proportion, almost all the prote...

In view of the increasing and devastating damage by rhinoceros beetle (Oryctes rhinoceros) to coconut palms in the middle of last century, many efforts were made to find an efficient natural control factor against this pest, which could not be controlled by pesticides. The basic procedures of these monitoring programmes are outlined together with the final detection of a virus disease in oil pa...

Dynoides canadensis sp. nov. is described from the south-western coast of British Columbia, Canada. This species differs its closely related species, D. elegans (Boone, 1923) ), by presence a smooth pleotelson without prominent rounded tubercle on basal part pleotelsonic sinus, sinus wall lacking crenulation; in having penial processes length 7.7 × width and acute distal apex instead 2.3 blunt ...

This study aimed to microencapsulate protein hydrolysates from stripped weakfish (Cynoscion guatucupa) industrial byproducts produced by Alcalase (HA) and Protamex (HP) spray drying, using maltodextrin as wall material. The physicochemical characteristics, in vitro antioxidant Angiotensin-I converting enzyme-inhibitory activities were evaluated during storage. Both microencapsulated showed sphe...

As a significant threat to agriculture, pests have caused great disservice crop production and food security. Understanding the mechanisms of pests’ outbreaks invasion is critical in giving sound suggestions on their control prevention strategies. The African rhinoceros beetle, Oryctes monoceros (Olivier), as most damaging pest palms, banana, sugarcane, pineapple, severely threatens due its abi...
