Lupine alkaloids as larval feeding deterrents for spruce budworm, Choristoneura fumiferana (Lepidoptera:Tortricidae)

Lupine alkaloids as larval feeding deterrents for spruce budworm, Choristoneura fumiferana (Lepidoptera:Tortricidae). Bentley, M. D.; Leonard, D. E.; Reynolds, E. K.; Leach, S.; Beck, A. B.; Murakoshi, I. (Dep. Chem., Univ. Maine, Orono, ME 04469, USA). Ann. Entomol. Soc. Am., 77(4), 398-400 (English) 1984. CODEN: AESAAI. ISSN: 0013-8746. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Twelve lupine alkaloids 8 from Lupinus polyphyllus, were tested in feeding bioassays against 6th instar budworm, C. fumiferana. Feeding deterrence was found in the alkaloid fraction of L. polyphyllus exts. Eight lupine alkaloids shown to be present in the ext. were tested at the rate of 25 mg/feeding disk. Of these compds., 13-trans-cinnamoyloxylupanine [5835-04-1] and 13-tigloyloxylupanine [57943-34-7] were highly deterrent, whereas lupanine [550-90-3], sparteine [90-39-1], 13-hydroxylupanine [15358-48-2], tetrahydrorhombifoline [3382-84-1], angustifoline [550-43-6], and 17-oxolupanine [4697-83-0], were not. Four alkaloids not present in L. polyphyllus, lupinine [486-70-4], epilupinine [486-71-5], a-isolupanine [486-87-3], and lupinyl-trans-cinnamate [92662-78-7] were not active at 25 mg/feeding disk. Clearly, there is wide variability in the response of spruce budworn larvae, which are not adapted to feeding on alkaloids to various alkaloids within the same structural class. If this variability in response is general among herbivores, perhaps the presence of an alkaloid is not significant with regard to defense, whereas diversity in structure of alkaloids may deter generalist grazers.

DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) Section cross-reference(s): 63 The total alkaloid content of whole, defatted, and defatted and debittered Lupinus mutabilis seeds was 2.60, 2.20, and 0.376 (sic). TLC sepn. yielded sparteine [90-39-1], 13-hydroxylupanine [15358-48-2], N-methylcytisine [486-86-2], lupanine [550-90-3], isolupanine [486-87-3], and 17-oxosparteine [489-72-5]. Extn. of the alkaloids in the lab and pilot plant is presented. The alkaloids were fractionated and some fractions converted into carbamates. Some fractions had insecticidal activity against Aedes aegypti larvae and Blattella germanica. Methods are presented for the manuf. of lupine oil and cake. After removal of the alkaloids, the cake was texturized and extruded, and the pertinent technol. discussed.
