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.

Cogon grass (Imperata cylindrica)

Alang-alang or cogon grass ( Imperata cylindrica ) is a plant species in Poaceae, annual grass, sharp leaf, long buds and scaly, creeping under the ground, very adaptive and grows in all climates which often become weeds on agricultural land. I. cylindrica has a sharp pointed tip of the bud and emerges from the ground, height of 0.2-1.5 m but in other places it may be more, short stems, rising up to the ground and flowering white or purplish, often with wreath of hair under the segment. Leaf strands in the form of long ribbons, lancet-tipped with a narrow base and gutter-shaped, 12-80 cm long, very coarse edge and jagged sharply, long hair at the base with broad, pale leaf bones in the middle. The flowers are panicles, 6-28 cm long with long-haired and white-colored ears for 1 cm which are used as a tool to blow off the fruit when ripe. Cogon grass breeds quickly with seeds that spread quickly with the wind or through rhizomes that quickly penetrate the soil. Alang-alang does...

Ralph Holzenthal caddisfly (Rhyacophila lignumvallis) from Corsica in Rhyacophila tristis (Schmid 1970) group

NEWS - Ralph Holzenthal caddisfly ( Rhyacophila lignumvallis Graf & Rázuri-Gonzales, sp. nov.) from the island of Corsica (France) was established as a new species in the Rhyacophila tristis (Schmid 1970) group based on morphological analysis and the mitochondrial cytochrome c oxidase subunit I (mtCOI), including sequences from 16 of the 28 species in the group. Rhyacophila Pictet 1834 with 814 living and 30 fossil species is the largest genus of caddisflies in the world, distributed mainly in the northern hemisphere, but also in temperate and tropical India and Southeast Asia. One of the groups is the R. tristis group in the branch Rhyacophila invaria . R. lignumvallis is most similar to Rhyacophila pubescens Pictet 1834, Rhyacophila tsurakiana Malicky 1984, Rhyacophila ligurica Oláh & Vinçon 2021, Rhyacophila harmasa Oláh & Vinçon 2021 and Rhyacophila abruzzica Oláh & Vinçon 2021. However, R. lignumvallis differs in the shape of the X tergum, the dorsal arm ...

Guinea grass (Panicum maximum)

Guinea grass or buffalo grass or green panic ( Panicum maximum ) is a plant species in Poaceae, annual grasses, growing upright to form clumps, strong, cultivated in all tropical and subtropical regions for very high value as fodder. P. maximum reproduces in very large pols, fibrous roots penetrate into the soil, upright stems, green, 1-1.5 m tall and have smooth cavities for diameters up to 2.5 mm. Propagation is done vegetatively and generatively. Ribbon-shaped leaves with a pointed tip, very many, built in lines, green, 40-105 cm long, 10-30 mm wide, erect, branched, a white linear bone, often covered with a layer of white wax, rough surface by hair short, dense and spread. The flower grows at the end of a long and upright stalk, open with the main axis length to more than 25 cm and the length of the bunches down to 20 cm. Grains have a size of 3x4 mm and oval. Seeds have a length of 2.25-2.50 mm and each 1 kg contains 1.2 - 1.5 million seeds. Guinea grass has two varieties. P...
