Proximate and Mineral Analysis of Coconutrhinoceros Beetle (Oryctesrhinoceros Linnaeus 1758) Larva Meal

A chromosomal analysis of Nepa cinerea Linnaeus, 1758 and Ranatra linearis (Linnaeus, 1758) (Heteroptera, Nepidae)

An account is given of the karyotypes and male meiosis of the Water Scorpion Nepa cinerea Linnaeus, 1758 and the Water Stick Insect Ranatra linearis (Linnaeus, 1758) (Heteroptera, Nepomorpha, Nepidae). A number of different approaches and techniques were tried: the employment of both male and female gonads and mid-guts as the sources of chromosomes, squash and air-drying methods for chromosome ...

Inorganic, organic, and encapsulated minerals in vegetable meal based diets for Sparus aurata (Linnaeus, 1758)

Substituting fishmeal (FM) with vegetable meal (VM) can markedly affect the mineral composition of feeds, and may require additional mineral supplementation. Their bioavailability and optimal supplementation levels depend also on the form of delivery of minerals. The aim of the study was to determine the effect of different delivery forms of three major trace elements (Zn, Mn and Se) in a marin...

Larva and pupa of Megatoma (s. str.) undata (Linnaeus, 1758) with remarks on biology and economic importance (Coleoptera, Dermestidae)

An updated description of the final larval instar and pupa of Megatoma (s. str.) undata (Linnaeus, 1758) (Coleoptera: Dermestidae) is presented. Several morphological characteristics of M. undata larvae are documented and discussed: antenna, epipharynx, mandibula, maxilla, ligula with labial palpi, hastisetae, terga, and condition of the antecostal suture. The paper is fully illustrated and inc...

Macroanatomical aspects of the gastrointestinal tract of the alpaca (Vicugna pacos Linnaeus, 1758) and dro- medary (Camelus dromedarius Linnaeus, 1758)

Although camelids and taxonomic ruminants share fundamental convergent properties, such as microbial fermentation and a sorting mechanism in the forestomach with a resulting high degree of digesta particle size reduction, there are important differences in the capacity to process high amounts of food. We describe qualitative and quantitative characteristics of the gastrointestinal anatomy of al...
