(n.) Any one of numerous species of hymenopterous insects belonging to the family Tenthredinidae. The female usually has an ovipositor containing a pair of sawlike organs with which she makes incisions in the leaves or stems of plants in which to lay the eggs. The larvae resemble those of Lepidoptera.
Example Sentences:
(1) The R-receptor of the solitary bee Callonychium petuniae is based on a pigment (P596) with a long lambda max, whereas in the sawfly Tenthredo campestris the G-receptor appears to act as filter to a pigment (P570), shifting its lambda max value to a longer wavelength and narrowing its bandwidth.
(2) 3,7-Dimethylpentadecan-2-ol was identified as the free alcohol in three species from two genera of pine sawflies (Hymenoptera: Diprionidae).
(3) A reduction in the sawfly-induced liver pathology as a consequence of the concurrent F. hepatica infection was also noted.
(4) Larvae of the sawfly Neodiprion sertifer (Hymenoptera: Diprionidae), when disturbed, discharge an oily oral effluent essentially identical chemically to the terpenoid resin of its host plant (Pinus sylvestris).
(5) In contrast, sawfly-dosed, fluke-infected lambs exhibited only moderate clinico-pathological signs of sawfly poisoning and no deaths occurred.
(6) Lophyrotomin was previously isolated from Lophyrotoma interrupta sawfly larvae in Australia.
(7) Whole ovaries of the sawfly, Acantholyda nemoralis Thoms., Tenthredinidae, Hymenoptera, were cultivated by the organ culture technique of Fell in the medium of Jones and Cunningham modified by doubling the contents of salts, sugars and lactalbumin hydrolysate and supplemented with an addition of folate.
(8) Possible factors responsible for the antagonistic effect of F. hepatica infection on sawfly poisoning in lambs are discussed.
(9) Larvae of the European birch sawfly Arge pullata were shown to contain lophyrotomin, an octapeptide liver toxin containing four D-amino acids.

(11) Improved control by advice on property management and a better knowledge of the population dynamics of the sawfly was suggested.
(12) The rumen and gut contained many larvae of the blue-black birch sawfly (Arge pullata).
(13) In a search for a region of DNA that will clarify the interordinal relationships we sequenced approximately 1080 nucleotides of the 5' end of the 18S ribosomal RNA gene from representatives of 14 families of insects in the orders Hymenoptera (sawflies and wasps), Neuroptera (lacewing and antlion), Siphonaptera (flea), and Mecoptera (scorpionfly).
(14) The pheromone perception system encountered in male pine sawflies thus differs clearly from that observed in moths.
