The effect of fungicides on silkworm larvae was analyzed with regard to the fact that these beneficial insects are usually affected by fungicides, Daily feeding on 1 and 2g/liter of carbendazim, a systemic fungicide, did not have significant effects on larval and pupal mortality. However the weight of the treated larvae showed considerable weight decrease up to 37% weight.. All the economic tra...

In this study, we examined the effects of repeated cold exposure (RCE) on the survival, energy content and stress protein expression of larvae of the Antarctic midge, Belgica antarctica (Diptera: Chironomidae). Additionally, we compared results between larvae that were frozen at -5°C in the presence of water during RCE and those that were supercooled at -5°C in a dry environment. Although >95% ...

The activity of juvenile hormone esterase (JHE) in feeding fifth instar larvae of Manduca sexta increases gradually with larval weight and rises to a peak after larvae pass the critical weight when juvenile hormone secretion ceases. Starvation of larvae of Manduca sexta (L.) that had exceeded the critical weight inhibited peak levels of JHE, but did not delay entry into the wandering stage when...

Unsatisfactory control of blood pressure (BP) leading to an increased rate of cardiovascular events is the main cause of mortality in haemodialysis. BP control has deteriorated since haemodialysis session times have been reduced. Inadequate BP control most often is due to a failure to achieve and maintain dry weight. Dry weight and normotension have been gradually omitted in the goals of dialys...

Sodium and fluid retention in dialysis patients is associated with hypertension and vascular changes that may ultimately lead to serious cardiovascular complications. Achieving and maintaining dry weight appears to be an effective but forgotten strategy in controlling and maintaining normal blood pressure among hypertensive patients on dialysis. A crucial question is how to determine 'dry weigh...

The food and feed sector requires new sustainable sources of protein innovative solutions for upcycling waste (former foodstuffs), which today is downcycled into energy or even wasted. This study aimed at evaluating the use former foodstuff streams as substrate Hermetia illucens (L.) larvae (black soldier fly larvae, BSFL) under long-term semi-industrial conditions. Different foodstuff-based mi...

Two kinds of experiments were conducted with Aethina tumida Murray larvae over four temperatures: "consumption" experiments, in which larvae and diet were weighed to determine food consumption rates under conditions of unlimited food and few conspecifics; and "competition" experiments, in which varying numbers of larvae were presented with the same amount of honey and pollen diet, and larval we...

Oryzias marmoratus is one of the ornamental aquarium fish species that live endemic to Towuti Lake, South Sulawesi, Indonesia. However, has been categorized as near threatened by IUCN. A current report showed could be cultivated. This research aims improve reproduction quality in cultivation using artificial feed containing Spirulina (A=0, B=3, and C=6) % dry weight. The study was conducted wit...

The current commercial production protocols for Atlantic cod depend on enriched rotifers and Artemia during first-feeding, but development and growth remain inferior to fish fed natural zooplankton. Two experiments were conducted in order to identify the underlying factors for this phenomenon. In the first experiment (Exp-1), groups of cod larvae were fed either (a) natural zooplankton, mainly ...

When larvae of the tenebrionid beetle, Zophobas rugipes, were allowed to disperse among 26 equivalent chambers in a circular dispersarium, distribution patterns were found to be a function of larval weight and number of larvae in the apparatus (N). Small larvae (x wt 250 mg) were significantly aggregated while large mature larvae (, 1000 mg) were highly overdispersed. Medium larvae were interme...
