Whole body sterol metabolism in insects has seldom been studied. We were able to design an appropriate study at a butterfly farm in Belize. We collected six larvas of butterfly (Morpho peleides), their food (leaves of Pterocarpus bayessii), and their excretions. In addition, six adult butterflies were collected. The sterols of the diet, the larva, and adult butterfly were analyzed by gas-liquid...

infestation of soil and night-soil with the eggs or larvae of soil-transmitted helminthes is very important factor in the transmission of these infections. the effect of various temperatures and different chemicals on the development of larva inside the eggs of ascaris, which is the most resistant eggs or larvae of helminthes, or destruction of developed larvae inside the eggs has been evaluate...

Two boys with ophthalmomyiasis caused by the first instar larva of the reindeer warble fly Hypoderma tarandi are reported. Both were 9 years old and came from the coast of northern Norway. One had ophthalmomyiasis interna posterior and one eye had been removed because of progressive pain and blindness. Histological examination showed the remains of a fly larva. The second boy had ophthalmomyias...

The hookworm related Cutaneous Larva Migrans is a common disease present in the tropic and subtropical areas of the world. The disease is self limiting and would naturally resolve within weeks. However, an unusual recurrence of the disease in a Ghanaian male after standard treatment was observed and is herein reported. A 52 year old Ghanaian male of Akan dissent was diagnosed with Cutaneous Lar...

Cutaneous larva migrans is a frequent phenomenon endemic in tropical and subtropical countries. In Europe only sporadic cases are reported. We present two cases of cutaneous larva migrans in two Slovenian tourists returning from a vacation in Brazil.

human visceral and ocular toxocariasis can occasionally be a serious or life-threatening condition, especially for children. the diagnosis and confirmation of the disease mostly based upon serological tests. the purpose of the present study was to evaluate somatic antigen with regard to its application in a routine diagnostic laboratory test. using gel-filtration chromatography, fraction no.1 o...

Creating sustainable bioeconomies for the 21st century relies on optimizing the use of biological resources to improve agricultural productivity and create new products. Arbuscular mycorrhizae (phylum Glomeromycota) form symbiotic relationships with over 80% of vascular plants. In return for carbon, these fungi improve plant health and tolerance to environmental stress. This symbiosis is over 4...

The life cycle of Lutzomyia shannoni (Dyar), was described for laboratory conditions with maximum daily temperature of 27-30 degree C, minimum daily temperatures of 22-27 degree C and relative humidity between 87-99%. Life cycle in each stage was as follows: egg 6-12 days (ave, 8.5 days); first stage larva 5-13 days (ave. 9.6 days); second stage larva 4-13 days (ave. 9.2 days); third stage larv...

The larva of Scydmoraphes sparshalli is redescribed. This is the first complete description of an immature Scydmoraphes with special focus on the chaetotaxic characters. The larva is unique among Cyrtoscydmini in having three pairs of stemmata, a very long sensory appendage of the antennomere II, mandibles with mesal row of microserrations interrupted by smooth portion of mandibular margin; max...
