Large conehead grasshopper (Ruspolia nitidula) flour promises as alternative nutrition source

NEWS - There is growing interest in alternative protein sources including tasty insect dishes. The large conehead grasshopper (Ruspolia nitidula) shows promise as a sustainable source of nutrition as global population growth and traditional livestock production increasingly strain environmental resources.

Cameroon’s abundant grasshoppers provide nutrients such as protein, amino acids and minerals that are essential for health and growth. The ecological benefits and health benefits make insects a solution for food security and improving future diets

Ngnaniyyi Abdoul from the University of Dschang in Cameroon and team studied the effects of replacing Clupea harengus fishmeal with R. nitidula meal in the diet of mice. Over 12 weeks, the researchers evaluated how this dietary change affected libido, sleep, hair growth and overall health.

Replacing fishmeal with R. nitidula meal resulted in significant health improvements in mice. Libido was increased with increased intromission and ejaculation compared to mice fed fishmeal or a protein-deficient diet.

Sleep quality improved and was more restful. Hair quality was significantly superior with 94.58% of hair in optimal condition compared to only 5.55% and 0.27% in the fishmeal and protein-deficient groups, respectively. Mice also showed greater weight gain.

"We highlight the significant potential of insects such as R. nitidula as an alternative protein source. Grasshoppers meet nutritional needs and offer substantial health benefits, including increased libido, better sleep and better hair quality with broad implications for animal and human diets," said Abdoul.

R. nitidula, which occurs naturally in Africa, Europe and Asia, has the potential to be a sustainable and nutrient-rich alternative protein source for animal feed and could play a role in addressing human malnutrition, especially in resource-limited environments.

Redflower ragleaf (Crassocephalum crepidioides)

Sintrong or ebolo or thickhead or redflower ragleaf ( Crassocephalum crepidioides ) are plant species in Asteraceae, terma height 25-100 cm, white fibrous roots, generally grow wild on the roadside, yard gardens or abandoned lands at altitude 200- 2500 m. C. crepidioides has erect or horizontal stems along the soil surface, vascular, soft, non-woody, shallow grooves, green, rough surface and short white hair, aromatic fragrance when squeezed. Petiole is spread on stems, tubular and eared. Single leaf, spread out, green, 8-20 cm long, 3-6 cm wide, longitudinal or round inverted eggshell with a narrow base along the stalk. Pointed tip, flat-edged or curved to pinnate, jagged rough and pointed. The top leaves are smaller and often sit. Compound flowers grow throughout the year in humps that are arranged in terminal flat panicles and androgynous. Green cuffs with orange-brown to brick-red tips, cylindrical for 13-16 mm long and 5-6 mm wide. The crown is yellow with a brownish red...

Six new species forming the Sumbana species group in genus Nemophora Hoffmannsegg 1798 from Indonesia

NEWS - Sumbawa longhorn ( Nemophora sumbana Kozlov, sp. nov.), Timor longhorn ( Nemophora timorella Kozlov, sp. nov.), shining shade longhorn ( Nemophora umbronitidella Kozlov, sp. nov.), Wegner longhorn ( Nemophora wegneri Kozlov, sp. nov.), long brush longhorn ( Nemophora longipeniculella Kozlov, sp. nov.), and short brush longhorn ( Nemophora brevipeniculella Kozlov, sp. nov.) from the Lesser Sunda Islands in Indonesia. The Lesser Sunda Islands consist of two parallel, linear oceanic island chains, including Bali, Lombok, Sumbawa, Flores, Sumba, Sawu, Timor, Alor, and Tanimbar. The oldest of these islands have been continuously occurring for 10–12 million years. This long period of isolation has allowed significant in situ diversification, making the Lesser Sundas home to many endemic species. This island chain may act as a two-way filter for organisms migrating between the world's two great biogeographic regions, Asia and Australia-Papua. The recognition of a striking cli...

New living fossil, Amethyst worm lizard (Amphisbaena amethysta), from Espinhaço Mountain Range, Brazil

NEWS - New species from the northern Espinhaço Mountains, Caetité municipality, Bahia state, Brazil. Amethyst worm lizard ( Amphisbaena amethysta ) is the 71st species of the genus with 4 precloacal pores and the 22nd species of Caatinga morphoclimatic domain. Identification of the new species shows the reptiles of the Mountains are far from complete and may contain greater diversity of endemic taxa. A. amethysta can be distinguished by its anteriorly convex snout, slightly compressed and unkeeled, pectoral scales arranged in regular annuli, four precloacal pores, distinct head shield, 185-199 dorsal and half annuli, 13-16 caudal annuli, a conspicuous autotomy spot between the 4th-6th caudal annuli, 16-21 dorsal and ventral segments in the middle of the body, 3/3 supralabials, 3/3 infralabials and a smooth and rounded tail tip. A. amethysta occurs in areas with an average elevation of 1000 meters in patches of deciduous and semi-deciduous forests associated with valleys, slopes, fore...
