What's the difference between locusta and spikelet?
Locusta
Definition:
(n.) The spikelet or flower cluster of grasses.
Example Sentences:

(9) Protein methylase II (protein O-methyltransferase, EC 2.1.1.24) was found in Dictyostelium discoideum amoebae, Astacus leptodactylus axonal, Locusta migratoroides neuronal, Torpedo marmorata electroplaque and Bos bovis stratial tissue and compared in both the soluble and particulate fractions.
(10) The relative position of the genes is conserved between Locusta and Drosophila, thus indicating conservation of mitochondrial gene order in insects.
(11) Electrophysiological studies have shown that both the 5-kDa and 4-kDa peptides depolarise the membrane and increase the membrane conductance of neurones freshly isolated from the thoracic ganglia of Locusta.
(12) Two distinct diuretic peptides affect the rate of fluid secretion of the Malpighian tubules in Locusta.
(13) High-performance liquid chromatography with electrochemical detection was used to measure N-acetyldopamine and N-acetyl 5-hydroxytryptamine in the cerebral ganglia of the African migratory locust, Locusta migratoria (fifth instar) exposed to lindane, a chlorinated insecticide.
(14) The peptide stimulates the contractions of the oviduct of Leptinotarsa as well as that of Locusta migratoria.
(15) Five of the six categories of haemocytes of Locusta migratoria, that is, the plasmatocytes, spherule cells, granulocytes, coagulocytes and oenocytoids, contain conspicuous granules of mucosubstance in their cytoplasm.
(16) They stimulate visceral muscle contractions of the oviduct and the foregut of Locusta migratoria and of the hindgut of Leucophaea maderae.
(17) A neuropeptide with adipokinetic activity in Locusta migratoria and hypertrehalosaemic activity in Periplaneta americana was purified by reversed-phase high performance liquid chromatography from the corpus cardiacum of the dragonfly, Libellula auripennis.
(18) Electron microscopic studies on developing follicles of Locusta migratoria show the vitelline membrane to be composed of two ultrastructurally distinguishable components: The vitelline membrane bodies (VMBs) and, in addition, fine granular material, cementing the VMBs together.
(19) An alpha-toxin-binding membrane protein, isolated from the head and thoracic ganglia of the locus (Locusta migratoria), was reconstituted into planar lipid bilayers.
(20) It has been previously shown that fucosterol-24,28 epoxide 3 is transformed into 5 in Locusta migratoria, desmosterol 4 being an intermediate.
Spikelet
Definition:
(n.) A small or secondary spike; especially, one of the ultimate parts of the in florescence of grasses. See Illust. of Quaking grass.
Example Sentences:
(1) Small transient all-or-none depolarizations (also termed in the literature fast prepotentials, spikelets, pseudospikes, d-spikes, or short latency depolarizations) and their association with lucifer yellow (LY) dye-coupling were analyzed in CA1-CA3 hippocampal pyramidal cells in urethane anesthetized rats.
(2) The isolates were grown on Sabouraud glucose agar for 2 days before being inoculated into boiled spikelets of Axonopus compressus (Gramineae) and then into induction medium (IM).
(3) Spikelets rose from base line as 3-10 mV depolarizing wavelets with a duration between 5 and 10 ms.
(4) The action potentials and the subthreshold spikelets were shown to be Na+ dependent and are presumably generated by a voltage-dependent inactivating Na+ conductance.
(5) Hooked macrohairs on the lemma of the spikelet show that morphological modifications in grasses for dispersal by attachment to the surface of animals were present in the Late Eocene.
(6) flower glume colour, degree of lateral spikelets development, hairy rechis of the ear, were observed in diallel crosses among the varieties Nutans 244, Trumpf, DZ-02389, Hiproly and Brachitic.
(7) Plateau potentials with a high threshold and high-threshold spikelets were Ca2+ dependent and seem to be generated by non-inactivating and possibly inactivating Ca2+ conductances.
(8) Relay cells, on the other hand, were strongly depolarized and fired spikelets at a greatly increased frequency during EOD-interruptions.
(9) It was found that (a) 15 of the 24 LY-injected pyramidal neurons (63%) showed dye-coupling; (b) spontaneous, anti- and orthodromically evoked spikelets (3-7 ms in duration; 3- to 12-mV peak) were recorded in 40 of 95 cells (42%); (c) there was a significantly higher probability of dye-coupled neurons with spikelets and of uncoupled ones without spikelets; (d) spikelet waveform and amplitude were unaffected by spontaneous or imposed polarizations; (e) large hyperpolarizations could reduce the rate and even prevent spikelets; and (f) spikelets could precede or follow spikes, the latter were more frequent with large depolarizations.
(10) Electrophysiological findings, and the association of dye-coupling and spikelets, suggest strongly that at least some spikelets are coupling potentials.
(11) Discovery of a female spikelet of the grass genus Pharus (Gramineae: Bambusoideae: Phareae) in association with mammalian hair in Dominican Republic amber provides the first fossil evidence of epizoochory.
