larval造句
1 These tracheoles may be termed the larval or provisional tracheoles, and they extend in bundles into the developing lacunae. 2 It always breeds in a larval condition, its external gills growing into great branching bushes on either side of its neck. 3 This fish feeds readily on larval Artemia, but fully grown adults are too large. 4 More commonly, larval numbers increase on pasture in summer and autumn giving rise to clinical problems during these seasons. 5 The entry of larval trichonemes into the lumina of the tubular glands generally provokes an inflammatory response together with marked goblet cell hypertrophy. 6 The nymphs, or first larval stages of mayflies, are also adapted to very particular conditions. 7 In the main, larval control would have to be near perfect in its efficiency and to allow very few adults to survive. 8 The larval stages occur in the gastric glands and can only be seen microscopically following processing of the gastric mucosa. 9 The larval stages remained clinging to the mast, to blow away in the next gale. 10 An insecticide designed to kill larval pests. 11 The larval stage of certain tapeworms, resembling a cysticercus but having the scolex completely filling the enclosing cyst. 12 Where Ancylostoma is also endemic, differential diagnosis may require larval culture although the treatment is similar. 13 Bees of these nine colonies took the caps off the larval cells, but then left the dead larvae inside. 14 Traditionally, ostertagiasis has been prevented by routinely treating young cattle with anthelmintics over the period when pasture larval levels are increasing. 15 It arises when an immune animal is suddenly exposed to a massive larval challenge, usually from a heavily contaminated field. 16 This is usually about 18 days after infection, but it may be delayed for several months when arrested larval development occurs. 17 In mild to moderate infections, there are no clinical signs during the pulmonary phase of larval migration. 18 Tannic acids, gossypol and tomatin in the diet hamper the larval growth of both species and tomatin has more pronounced effect on the tobacco budworm. 19 Adults have lungs, But a gill slit persists from the larval stage side Behind the head. 20 Mosquito breeding can be forestalled by killing the insect at its adult or and larval pupal stages. 21 They must obtain it from decomposed plants they eat while in their larval stage, living in shallow waters. Plants make phytosterol, which is converted to cholesterol in the mosquito's gut. 22 As the name suggests, the caveserves as the home to glowworms, specifically Arachnocampa luminosa, which are a type of fungus gnat species that glow in their larval stage. 23 The transgenic foliage consumed by insects induced the increase of larval mortality, and decrease of larval wet weight gain, faecal output, pupal weight and egg deposition. 24 Vector control measures (mainly larviciding in one site) substantially reduced larval and pupal counts and "pushed" mosquito breeding to alternative containers. 25 The redia feeds on snail tissue and buds off other larval stages through asexual reproduction. 26 Hydatid disease is a worldwide zoonosis produced by the larval stage of the Echinococcus tapeworm. 27 Methods The density surveillance was conducted by the spoon method, and 10% beta-cypermethrin and 1% Abate larvicide were deployed on the spot for larval control. 28 The ghostly looking Mexican axolotl retains some of its larval features for life, including its feathery pink external gills. 29 The entomologist is working with the Ministry and WHO to conduct larval and mosquito surveys to develop a strategy for vector control. 30 On all host plants, significant relationships were founded between larval survival, duration of larval stage, pupal weight, adult eclosion rate and fecundity.
