this experiment was conducted to increase the resistance of tiger barb (capoeta tetrazona ) against environmental stress by feeding brackish water gammarus sp. powder as supplementary diet in three levels (25%, 50% and 75%) and three replicates pe group compared to control group for 60 days. fishes was fed with 4 diet treatment containea of: 100% artificial diet (control group), 25% brakish wat...

pomegranate fruit moth (pfm), apomyelois ceratoniae zeller is a major pest of pomegranate in iran. in this study, the effect of four diets including pistachio, pomegranate, semi-artificial and artificial diets were studied on biological parameters of pfm in a growth chamber under controlled conditions at 30 ± 2 °c, 65 ± 5% rh and 16:8 (l: d) h. the results demonstrated that the longest incubati...

Diapetimorpha introita (Cresson) (Hymenoptera: Ichneumonidae) is a native ectoparasitoid of Spodoptera spp. pupae. This parasitoid has been reared in the laboratory on an artificial diet devoid of any insect host components. However, wasps reared on this artificial diet had reduced fecundity. Efforts to increase fecundity included supplementing the diet with cell culture media conditioned with ...

A number of concentrations of PRO-PLEXTM, a protein rich food additive, were incorporated into an artificial diet to determine its effect on the predatory beetle, Carcinops pumilio (Erichson). The impact of this host-free artificial diet on developmental time, larval weight, oviposition and mortality was assessed. When C. pumilio is fed on a host-free diet, the total development of egg to adult...

The impact of a tapioca-based artificial diet on the developmental rate, life history parameters, and fertility was examined over five consecutive generations for the cotton bollworm, Helicoverpa armigera Hubner (Lepidoptera: Noctuidae), a highly polyphagous pest of many agricultural crops. The study showed that when fed the tapioca-based artificial diet during larval stage, larval and pupal de...

The bean pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae), is a serious pantropical pest of grain legumes. A suitable artificial diet is desirable for producing uniform insects for commercial purposes or research. Three previously described artificial diets, 1 newly-developed artificial diet, and cowpea (Vigna unguiculata (L.) Walp. (Fabales: Fabaceae)), the natural hostplant of M. ...

The impact of an insect-free artificial diet provided at nymphal and/or adult stage upon the developmental rate, life table parameters, and fertility table parameters was examined for Podisus maculiventris (Say). This study showed that when fed an insect-free artificial diet during both the nymphal and adult stage, developmental time was prolonged, preoviposition period was extended, and reprod...

Wild population of the olive fruit fly (Bactrocera oleae (Rossi.)) was adapted to the laboratory conditions feeding on both olive fruits and an artificial diet. Infested fruits were brought to the laboratory and emerged adults used as the initial generation of the laboratory colony. After eggs were laid into the fruits, they were dissected and first instars were transferred to an artificial die...

Hypothesis: Interactions between diet and temperature affect reaction norms for growth rate in ectotherms. Organisms: Full-sib families of the small cabbage white butterfly, Pieris rapae, derived from field populations near Seattle, WA, USA. Methods: We used a split sib-family experimental design with two food treatments (collard leaves and artificial diet) and four test temperatures (11, 23, 3...
