Article Synopsis
- The study investigates how different feeds made from weeds, agro-byproducts, and chicken feed affect the growth and nutritional value of field crickets, a potential solution for global malnutrition.
- Various feed formulations were tested, showing that those with higher protein content led to better growth rates and survivorship, with significant differences in body mass and length observed between the crickets fed formulated feeds versus the control.
- The results suggest that using alternative feeds like weeds and agro-byproducts can enhance the growth and nutrition of crickets, making them a more sustainable food resource while also reducing feeding costs.
Article Synopsis
- Gryllus bimaculatus, a cricket species, is recognized as a valuable source of nutrition for food and feed, but its response to temperature for effective mass production is not well-studied.
- The research tested G. bimaculatus at temperatures from 20°C to 40°C, finding optimal life cycle completion and growth at around 32°C, with the highest population growth rate at 35°C.
- Results provide crucial insights for farmers by revealing that G. bimaculatus can thrive in temperatures between 20°C and 37°C, allowing for better management and sustainability in cricket farming globally.
Following its recent invasion of African countries, fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae), now co-exists with resident stemborers such as Busseola fusca (Lepidoptera: Noctuidae) and Chilo partellus (Lepidoptera: Crambidae) causing severe damage to maize crops. Due to niche overlap, interspecific interactions occur among the three species, but the mechanisms and degree remain unclear. In this study, we assessed plant-mediated intraspecific and interspecific interactions, predation in laboratory and semi-field settings, and larval field occurrence of S.

- * The review highlights over 60 species of edible crickets consumed in 49 countries and notes their high protein (55-73%) and lipid (4.3-33.44%) content, along with essential vitamins and minerals that make them a nutritious alternative.
- * Additionally, the farming of crickets presents various advantages, including contributions to economic development, pest management, and use in food preservation, while the reviewed species are considered safe for consumption.
A new native edible cricket species, Scapsipedus icipe Hugel and Tanga, has been described in Kenya for the first time. However, there is lack of information on suitable diets and their effects on the developmental time, survival, weight gain, body length, growth index, preoviposition, oviposition, postoviposition, fecundity, egg eclosion period, adult emergence, and longevity of this species, which are prerequisite for large-scale production. In this study, six diets (wheat bran, soybean, fish offal, pumpkin leaf, carrot, and maize meals) selected to vary in protein, carbohydrate, and fat content were evaluated.
View Article and Find Full Text PDFA new cricket of the genus Scapsipedus is described from Kenya. The distribution, acoustic behavior, including call and courtship song, mitochondrial sequences, and data on the biology of that new species are given. This edible cricket is a very promising species for mass production for food and feed.
