Breeding pair insect. True breeding pairs are rare in amphibians or reptiles, although the Australian Shingleback is one exception with long-term pair-bonds. Some fish form short term pairs and the French angelfish is thought to pair-bond over a long term. True breeding pairs are quite common in birds. Breeding pair arrangements are rare in mammals, where the prevailing patterns are either that the male and female only meet for copulation (e.g. brown bear) or that dominant males have a harem of females (e.g. walrus). Breeding pair Breeding pair is a pair of animals which cooperate over time to produce offspring with some
Commercial butterfly breeding biological pest control. Captive breeders employ cost-effective and sustainable methods of plant propagation needed to provide larval food for their stock. Green houses, hydroponics, drip irrigation, and organic-based methods are used to control disease costs and create high plant yields. Pesticides are not used in the breeding of stock. Captive breeders reduce the exposure of laboratory bred stock to naturally curing predators, parasites and diseases that occur in wild stock by rearing butterflies in enclosed environments. The butterfly and moth larvae are typically raised in containers in various densities dependent upon the predetermined protocols. Some butterfly larvae best raised in
