Larva Black Soldier Fly (BSF) spesies Hermetia illucens mengandung nutrisi protein yang berpotensi menjadi sumber pakan alternatif hewan peliharaan ramah lingkungan, berkelanjutan, dan memiliki komposisi ideal. Namun, laporan penggunaannya masih belum diketahui sebagai bahan kucing. Uji palatabilitas komersial dengan penambahan tepung maggot bertujuan untuk mengetahui daya terima dikonsumsi. di...

We report for the first time the expression of multiple protease activities in the first instar larva (L1) of the flesh fly Oxysarcodexia thornax (Walker). Zymographic analysis of homogenates from freshly obtained L1 revealed a complex proteolytic profile ranging from 21.5 to 136 kDa. Although some activities were detected at pH 3.5 and 5.5, the optimum pH for most of the proteolytic activities...

THE complex chemical changes associated with metamorphosis have long been of interest to biochemists, but a detailed study of one type is not yet available, in spite of much attention having been paid to the silkworm. The subject of this study is the sheep blow-fly Lucilia sericata Meigan. This insect is very suitable for an investigation of this kind since the prepupal stage, morphologically s...

CERTAIN changes in the chief chemical constituents of tissues have been studied during the metamorphosis of Lucilia sericata Meigan, commonly known as the green-bottle or sheep blow-fly by Evans (3). Since histolysis and histogenesis are very well marked in this species, it was thought advisable to extend the study to a member of a lower order in which the changes are not so drastic. A suitable...

We report that a stage-specific developmental program, dauer larva formation, is temporally regulated by four heterochronic genes, lin-4, lin-14, lin-28, and lin-29. The effects of mutations in these four genes on dauer larva formation have revealed that they regulate two different processes of dauer larva formation: (1) a decision specifying the larval stage at which dauer larva development in...

Drosophila melanogaster is a widely used model organism for studying neurological diseases with similar neurotransmission to mammals. While both larva and adult Drosophila have central nervous systems, not much is known about how neurotransmitter tissue content changes through development. In this study, we quantified tyramine, serotonin, octopamine, and dopamine in larval, pupal, and adult fly...
