Leland Ossian Howard
Leland Ossian Howard (June 11, 1857 – May 1, 1950) was a pioneer American entomologist who worked in the US Department of Agriculture. Serving as the chief of the bureau of entomology, a successor to C.V. Riley, he helped establish economic entomology as a profession in the United States and strengthened research activities, helping establish laws to prevent the introduction of agricultural pests. He was a specialist on the Hymenopteran family Chalcididae, which are parasitic and contributed to the introduction of biological control agents for pest management. Howard also took an interest in medical entomology. Early life Howard was born to Ossian Gregory Howard, a lawyer, and Lucy Denham Thurber on 11 June 1857. His relatives from his mother's side included the Harvard astronomer E.C. Pickering while other distant relatives included Senator J.M. Howard and President William Howard Taft. Shortly after his birth, the family moved from Rockford, to Ithaca, New York where his fat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Encyrtidae
Encyrtidae is a large family of parasitic wasps, with some 3710 described species in about 455 genera. The larvae of the majority are primary parasitoids on Hemiptera, though other hosts are attacked, and details of the life history can be variable (e.g., some attack eggs, some attack larvae, others are hyperparasites, and some Encyrtidae develop as parasitoids of ticks). They are found throughout the world in virtually all habitats, and are extremely important as biological control agents. They may also present as an ecological threat to the population of some species. For example, the endangered ''Papilio homerus'' butterfly is parasitized at a rate of 77%, making them the main contributor to egg mortality in this (and other) butterfly species. Some species exhibit a remarkable developmental phenomenon called "polyembryony", in which a single egg multiplies clonally in the host and produces large numbers of identical adult wasps. Even more remarkably, some of the larvae are larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egg (biology)
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , the o ...

Tick
Ticks (order Ixodida) are parasitic arachnids that are part of the mite superorder Parasitiformes. Adult ticks are approximately 3 to 5 mm in length depending on age, sex, species, and "fullness". Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are from the Cretaceous period, around 100 million years old. Ticks are widely distributed around the world, especially in warm, humid climates. Ticks belong to two major families, the Ixodidae or hard ticks, and the Argasidae, or soft ticks. ''Nuttalliella,'' a genus of tick from southern Africa is the only member of the family Nuttalliellidae, and represents the most primitive living lineage of ticks. Adults have ovoid/pear-shaped bodies (idiosomas) which become engorged with blood when they feed, and eight legs. Their cephalothorax and abdomen are completely fused. In addit ...

Ixodiphagus Hookeri
''Ixodiphagus hookeri'', the tick wasp, is an encyrtid wasp which lays its eggs into ticks. It seems to use a symbiotic bacteria, ''Wolbachia pipientis'', to weaken the tick's immune system. Description ''Ixodiphagus hookeri'' is a small wasp which has the typical morphology of an encyrtid wasp and is blackish in colour, it measures 0.8-0.9mm in length and has a wing length span of 1.5mm. Its head is dorsally flattened with very large compound eyes. In females, the antennae have eleven segments and the antennae are club shaped; while in males they have ten segments and are thread-like. Biology ''Ixodiphagus hookeri'' has a short flight period in the summer in Europe. The female normally oviposits an egg into the body of an unfed nymph of ''Ixodes ricinus'', but has been recorded ovipositing in the adults of ''Rhipicephalus sanguineus''. The egg remains in diapause until the nymph engorges on vertebrate blood, at which point the egg becomes active. Some eggs are not successful, a ...
