“…This survival rate is lower than values reported elsewhere for other reared cricket species, which range from 76 to 100% at the age of 3-4 weeks (Clifford et al, 1977;Neville and Luckey, 1962;Tyree et al, 1974). It is also lower than values recently reported for T. testaceus (Megido et al, 2016).…”

This study evaluated survival and growth of Cambodian field crickets (Teleogryllus testaceus) during captivity when fed a set of local weed species, agricultural and food industry by-products. Wild individuals were caught at two locations in Cambodia, kept in pens and fed commercial chicken feed until the second generation off-spring hatched. First larval stage nymphs from this generation were collected and used in a 70-day feeding trial with one control treatment (chicken feed) and 12 experimental treatments (rice bran, cassava plant tops, water spinach, spent grain, residue from mungbean sprout production, and Alternanthera sessilis, Amaranthus spinosus, Commelina benghalensis, Cleome rutidosperma, Cleome viscosa, Boerhavia diffusa and Synedrela nodiflora). The crickets were kept in plastic cages and feed intake, weight and survival of crickets were recorded weekly. Overall survival did not differ between chicken feed and the experimental treatments with the exception of crickets fed B. diffusa, which had lower survival. From day 35 to day 49, survival on A. sessilis was also lower (P<0.05) than on chicken feed. There was no difference in weight between crickets fed chicken feed, cassava tops and C. rutidosperma. However, crickets fed A. sessilis, A. spinosus and B. diffusa weighed less than those fed chicken feed already at day 21. The feed conversion rate ranged from 1.6 to 3.9 and was ≤1.9 in crickets fed chicken feed, cassava plant tops and C. rutidosperma. Thus this study shows that it is possible, using simple means, to rear Cambodian field crickets. Cassava plant tops and C. rutidosperma both have great potential as cricket feed and the other weeds, with the exception of A. sessilis, A. spinosus and B. diffusa, agricultural and food industry by-products tested, also showed potential.

“…It is known that the house cricket (Acheta domesticus) can survive and grow well on a variety of organic materials (Makkar et al, 2014) including forage diets (Tyree et al, 1974). The study by Megido et al (2016) indicate that T. testaceus might have similar capacity.…”

“…Despite high feed intake and relatively high CP concentration (>200 g/kg DM) in earlycut red clover, the growth of AD on all red clover diets was lower than on the control diet. Similarly, Tyree et al (1976) found that AD fed timothy or alfalfa as sole feeds for 28 days had lower survival rate and lower average weight than crickets fed a mixed diet. On the other hand, Miech et al (2016) showed that cassava tops and purple cleome (Cleome rutidosperma) can work as sole feed for field crickets.…”

“…Since AD exist naturally in Europe (https://www.gbif.org/species/1718308), When investing in new food production systems, it is of paramount importance not to use foodstuffs suitable for humans as animal feed or create systems that rely heavily on transportation and import of feeds (Berggren et al, 2019). As AD can utilise food by-products and forages, it is possible to rear this species in ways that do not compete with humans for food sources (Caparros Megido et al, 2016;Miech et al, 2016;Tyree et al, 1976). Field crickets (Teleogryllus testaceus) reared in captivity and fed diets including one single agricultural by-product (tops of cassava, Manihot esculenta) or weed (purple cleome, Cleome rutidosperma) displayed similar growth and feed efficiency to individuals reared on poultry feed (Miech et al, 2016).…”

“…Poultry feed is commonly used in cricket rearing, but cannot be regarded as a sustainable feed, as this does not exploit AD's ability to utilise lower value organic materials (Berggren et al, 2019;Miech et al, 2016). Tyree et al (1976) has previously shown AD to grow well on diets mainly consisting of grasses and legumes, namely lucerne (Medicago sativa). The leguminous species red clover (Trifolium pratense) is a commonly used ruminant feed in Europe.…”

This study evaluated the potential of red clover as a sole diet for house crickets (Acheta domesticus, AD) and the effect of ensiling or drying red clover biomass on growth, survival and water consumption of AD. Wild AD were caught near Uppsala, Sweden, and reared in a climate-controlled room under a 12-h light regime. One day-old third-generation cricket nymphs (n=2,880) were used in a 56-day feeding trial. The experimental diets (n=8) were early-cut (pre-bloom) and late-cut (late-bloom) red clover, preserved as frozen-fresh, dry-silage, haylage and hay, and a control diet. All clover diets were fed as sole diets with salt block available ad libitum in every treatment. Feed dry matter intake, feed conversion ratio (FCR, kg feed dry matter per kg weight gain), number and weight of crickets and water consumption were recorded every five days. FCR was higher for late-cut than early cut-red clover, but overall cricket weight and survival rate did not differ between cutting times (P=0.939). FCR, weight and survival were not affected by forage conservation method. Total feed consumption was highest for red clover hay. Crickets fed red clover diets had lower (P<0.01) weight and higher FCR than crickets fed the control diet, but their survival rate was not different from that of control crickets during the first 25 days of life. Water consumption of AD fed the control diet was about half that reported for pigs and poultry. Crickets fed on fresh red cover had lower (P=0.04) water consumption compared with crickets fed dried or ensiled red clover, but ensiling did not reduce water consumption compared with hay. Red clover cannot be recommended as a sole feedstuff for AD, but early and late-cut red clover had similar effects. The possibility to partly include late cut red clover in cricket diets is interesting from an ecosystem service perspective since the flowering crop will provide feed for declining populations of bees and other pollinators.

http://www.eje.cz and high fecundity. In addition, it is more environmentally friendly and less expensive to rear insects for food.The fi eld cricket, Scapsipedus icipe Hugel and Tanga (Orthoptera: Gryllidae) (Tanga et al., 2018) is edible and could be used to reduce malnutrition at local and global levels. It is a native of Kenya and well adapted to the tropical climate of Africa including Madagascar (Tanga et al., 2018;Magara et al., 2021). This insect is highly nutritional in terms of protein, fat, fi bre, mineral and vitamins (Murugu et al., 2021). As food for humans, this cricket can be fried and eaten as a snack or processed into fl our and still remain highly nutritional. It can also be offered as feed for other insects (Mwale et al., 2022), or as food for livestock, such as pigs (Miech et al., 2017). Like other Gryllidae, S. icipe can feed on a variety of foods including agricultural by products, vegetable materials, commercial food, forage and even weeds (
