释义 | larval adjective biology specializeduk /ˈlɑː.vəl/ us /ˈlɑːr.vəl/ relating to a form of an insect or an animal such as a frog that has left its egg but is not yet completely developed: 幼虫的 Strong winds can catch this early larval form of the insect and carry it up to 50 miles.强风可以将这种昆虫的幼虫吹到50英里以外。 The army worms are the larval stage of a common moth.行军虫是一种蛾的幼虫。 Compare pupal See larva These organisms are a tiny, larval form of a type of jellyfish. In its larval stage, the insect feasts on corn root systems. From eggs, tiny larval fish will feed on a dollop of oil and fat.

Current studies are being carried out to determine the pharmacology, ion dependence and molecular basis for larval tegumental serotonin transporters. Thus, larval migration in rodents may be used in infectivity studies not requiring patency. In the present study, tunnel length in maize tended to increase with age of the plant, while larval weight per cm tunnel produced decreased. Larval infestation rates on susceptible wheat tended to show the same patterns as oviposition rates (fig. 2). An advantage of the zebrafish is its transparent nature during embryonic and larval stages. Those populations sourced from lodgepole pine did not differ in fecundity according to which larval food had been eaten. Larval density was not precisely controlled, and with this procedure ranged between 100 and 200 individuals per vial. Levels of natural populations of larval parasitoids were measured by their parasitism rate. The populations examined in this study also showed significant variability in larval growth rate (fig. 2a). Both species of parasitoid delay larval development until the host has reached full size and has entered the ground to pupate. In other words, the longer the female's larval and pupal stages were, the bigger were her eggs. One larva was observed to pass through six larval stages. Larval performance was studied by following larvae enclosed in cages from newly moulted second instars to third instars in the field. It seems to be clear that the highest larval reduction percentage in faecal cultures is related to the maximum elimination of fungal material into faeces.
