    Description / Table of Contents: Résumé Des expériences ont été menées au laboratoire pour examiner si la phéromone sexuelle synthétique de C. fumiferana pouvait altérer le comportement d'appel de femelles vierges de la même espèce. Un appareil a été conçu pour libérer alternativement — à des intervalles déterminés — un courant d'air portant de la phéromone sexuelle ou un courant d'air pur, dans plusieurs flacons contenant des femelles vierges. Le comportement sexuel de mouches de 0 et 2 jours a ainsi été observé. Indépendamment de l'exposition des femelles à la phéromone, il y avait deux pics quotidiens d'activité d'appel, l'un dans l'après-midi et l'autre après le crépuscule. Des papillons exposés au 1×10−6 mg ou 1×10−3 mg de phéromone avaient un premier pic d'appel au moins antérieur de 2 heures par rapport aux témoins. Ainsiily a vait un plus grand nombre de papillons engagés dans une activité d'appel en présence de la phéromone que chez les témoins.
    Notes: Abstract The calling behaviour of 0-day-old and 2-day-old virgin female eastern spruce budworm moths, Choristoneura fumiferana (Clem.) was observed during exposure to different concentrations of the synthetic female sex pheromone. Regardless of whether the females were exposed to pheromone or not, there were two daily peak periods of calling activity, one in the afternoon and the other after dusk. Those moths exposed to pheromone commenced calling at least 2 h earlier during their first peak of calling activity. Also, a greater number of moths engaged in calling when exposed to pheromone than those under control conditions.

    Description / Table of Contents: Résumé L'application topique d'un analogue de l'hormone juvénle, l'Altosid, sur les larves de la mouche de la viande Sarcophaga bullata, inhibe l'éclosion imaginale. Tandis que la tête et le thorax sont résistants à cet analogue de l'hormone, l'abdomen y est très sensible. Selon la dose du produit appliquée, différents effets morphogénétiques ont été observés au niveau de l'abdomen, tels que l'absence de rotation des genitalia du mâle, la réduction du nombre des soies et microtriches, l'orientation irrégulière des soies et l'inhibition de la différenciation des genitalia. Les mouches traitées ont été examinées histologiquement. Les muscles des genitalia et de l'abdomen ne se sont pas développés cependant que les muscles thoraciques montraient des dystrophies. La signification de ces effets sur les muscles est discutée en rapport avec l'inhibition de l'élosion imaginale chez les insectes traités par l'Altosid.
    Notes: Abstract Topical application of a juvenile hormone analogue, Altosid, onto the larvae of the fleshfly, Sarcophaga bullata, inhibited adult eclosion. While the head and thorax were resistant to the hormone analogue, the abdomen was highly sensitive. Depending on the dose of the compound applied, various morphogenetic effects were noticed on the abdomen such as failure of rotation of male genitalia, reduction in the number of bristles and microtrichiae, irregular orientation of bristles and inhibition of differentiation of genitalia. The affected flies were examined histologically. The muscles of the genitalia and abdomen failed to develop, while thoracic muscles exhibited dystrophic changes. The significance of these muscular effects is discussed in relation to the inhibition of adult eclosion of Altosid treated insects.

    Glucosinolate levels in cotyledons of mustard,Brassica juncea L. and rape,B. napus L. do not determine feeding rates of flea beetle,Phyllotreta cruciferae (Goeze) (1990)

    Notes: Abstract Sinigrin (allyl glucosinolate), the major glucosinolate in the cotyledons ofBrassica juncea cv. Cutlass, occurred in the highest concentration and amount at seedling emergence and declined during growth. Glucobrassicin (3-indolylmethyl glucosinolate), the major glucosinolate in the cotyledons ofB. napus cv. Westar, occurred in the lowest concentration and amount at seedling emergence. The amount of glucobrassicin per cotyledon pair increased about fourfold during 14 days of growth, but its concentration remained relatively unchanged because of “dilution” by increasing cotyledon biomass. These different glucosinolate profiles indicate a different metabolic control and different biological function for sinigrin and glucobrassicin. The flea beetle,Phyllotreta cruciferae Goeze, does not discriminate between cotyledons having sinigrin or glucobrassicin since the two crucifers were fed upon equally in choice tests. Restricting the concentration of sulfur in the nutrient medium accelerated the decline of sinigrin inB. juncea cv. Cutlass but did not alter the feeding rate ofP. cruciferae compared to controls. Sulfur restriction reduced glucobrassicin inB. napus cv. Westar to undetectable levels and somewhat reduced the feeding rate of P.Cruciferae. Nevertheless,P. cruciferae still fed actively on cotyledons ofB. napus cv. Westar depleted of glucosinolates and severely damaged many of them. Since glucosinolate type and concentration had little effect on feeding response, reduction or elimination of foliar glucosinolates alone would not seem a useful strategy for protecting seedlings of these two crucifers from flea beetle damage.

    Notes: Abstract (Z,Z,Z)-3,6,9-Eicosatriene and (Z,Z,Z)-3,6,9-heneicosatriene have been identified as components of the sex pheromone of the noctuid,Caenurgina erechtea (Cramer), the forage looper. Structural assignments were made on the basis of spectroscopic and chromatographic data and were confirmed by comparison with synthetic material. Flight tunnel behavioral studies demonstrated that either component, when tested individually, would elicit wing fanning responses in males; however, mixtures of the two components increased this response and were essential for initiation of upwind flight and landing. In field experiments, traps baited with either component alone captured few or no adult forage looper males while those baited with both components captured several target males.

    Notes: Abstract All four geometrical isomers of 7,9- and 8,10-dodecadienes with acetate, alcohol, and aldehyde functional groups were synthesized and field tested. The field survey produced sex attractant lures for 14 insect species. Species in the generaCydia, Grapholita, Eucosma, Pelochrista, Petrova, Phenta, Hedya, and Pseudosciaphila were captured. Defined lures were developed for some of the species captured. Gas chromatographie retention times for all geometrical isomers of 7,9- and 8,10-dodecadienes with acetate, alcohol, and aldehyde functional groups are reported. A study of the isomerization of 8,10-dodecadienyl acetates and aldehydes impregnated in rubber septa is reported.

    Notes: Abstract A sex pheromone extract from fall cankerworm moths,Alsophila pometaria, attracted conspecific males in field tests. Four EAG-active components were isolated from the extract and identified by GC-MS, highfield PMR spectroscopy, and microchemical techniques asn-nonadecane (I), (Z,Z,Z)-3,6,9-nonadecatriene (II), (Z,Z,Z,E)-3,6,9,11-nonadecatetraene (III), and (Z,Z,Z,Z)-3,6,9,11-nonadecatetrane (IV). Studies of the behavioral responses of male moths in a flight tunnel to the isolated components showed II, III, and IV were the major components of the sex pheromone. No sex pheromone behavioral responses were observed for I.

    Notes: Abstract In addition to three known sex lure components [(Z)-11-hexadecenyl acetate, (Z)-11-hexadecenal, and (Z)-11-hexadecenol], (Z)-9-tetradecenyl acetate was field-proven as a trace coattractant for malePlutella xylostella, with an optimal content below 0.01% in blends. This potent four-component lure for diamondback males also attractedCrymodes devastator males, and in this respect is not different in its attractancy from virgin diamondback females. Replacement of (Z)-9-tetradecenyl acetate in the four component lure with (Z)-9-tetradecen-1-ol, at the level of 10% of the total lure mixture, did not alter its attractancy for diamondback males, but it did inhibit attraction ofCrymodes devastator. The status of biologically active components as possible sex pheromones or para-pheromones is discussed.

Flight-tunnel bioassays and field-trapping experiments confirmed that the two tetraenes together with (Z,Z,Z)-3,6,9-nonadecatriene are sex pheromone components. While traps baited with either tetraene individually captured conspecific males in field-trapping experiments, addition of the triene, which captured no males by itself, to either tetraene resulted in synergistic responses.
