Female mosquitoes use abiotic and biotic factors, such as the presence of heavy metals or parasites, to determine the acceptability of oviposition sites. Some biotic factors can originate from mosquito larvae. When mosquito larvae are starved or infected with trematode metacercaria, they render associated water unacceptable to ovipositioning females. Internal symbiotes are common in wild mosqui...

Polyester pad was utilized as solid support for rearing Cochliomyia hominivorax Coquerel larvae in liquid diet and compared with the ground meat diet. There were no significant differences in the mean third instar larvae and pupal weights, number of pupae, emergence and rearing efficiency. The tests were conducted through four consecutive generations, presenting no detectable effect in any of t...

Larval therapy is a biological 'dressing' for chronic ulcers which is used for debridement, to initiate healing and to reduce bacteria and unpleasant odour. One condition for being able to employ larval therapy is access to disinfected larvae of good quality. We therefore started rearing Lucilia sericata larvae in 1998. Rearing necrophagous larvae in a hospital setting makes it essential to con...

Captive rearing of insect pests is necessary to understand their biology and to develop control methods. The avian nest fly, Philornis downsi Dodge and Aitken, is a blood-sucking parasite during its larval stage and a serious threat to endemic birds in the Galapagos Islands where it is considered invasive. In order to procure large numbers of flies for biological studies, rearing media and diet...

rearing methods for bracon hebetor (say) (hym., braconidae) were investigated in the series of laboratory experiments designed to enhance the yield of the mass rearing of this parasitoid for biological control of lepidopteran field and stored product pests. in these experiments, the effects of parasitoid and host densities on fertility and sex ratio of b. hebetor were assessed. in parasitoid de...

Larval rearing Larval development usually take five months in the field. The early hatched young larvae are fragile so we kept them to grow inside fruits for about 15 days. Then larvae were transferred to artificial diets. Mature larvae drill out diet and pupate in moist sands (Fig. 4). We used several diet formulations recommended from other fruit flies rearing. Evaluation was carried out base...

NorthAmerican tiger beetles (Cicindela spp. L.) have been reared in the laboratory for more than a century, and here we summarize the relevant literature to develop a general rearing protocol. We used this protocol to experimentally overwinter adults in the laboratory and observe variation in oviposition and fecundity among several species. Overwintering experiments, involving Þve North East No...

Abstract Larval cod require live prey as food, and concentration (PC) feeding frequency (FF) often affect their growth survival. Apart from this, water exchange rates/water flow (WER/WF) current (WC) also the resident time in tank larval/early juvenile behaviour, respectively. High is known to induce stress finfish larvae, this response believed be dependent on larval developmental stage. Thus,...

Egg production of cultivated broodstocks of orange-spotted grouper, Epinephelus coioides and larvae rearing were surveyed in Iran from 2008 to 2012. . Broodstocks were obtained by rearing of 7 wild juveniles (587.57 ± 132.63 g body weight) which were caught from the north of Persian Gulf in October 2008 and reared to December 2012.. Captured juvenile fishes were fed using defrosted trash fish a...
