Juvenile Hormone Mimic

Simplified preparations, such as isolated abdomens, were used to study the effect of farnesyl methyl ether (a juvenile hormone mimic) and ecdysone on ovarian development and adult development in Malacosoma pluviale. Untreated isolated abdomens showed very limited ovarian development and failed to form imaginal cuticle, thus indicating a lack of adult development. Topical application of farnesyl methyl ether to the isolated abdomens blocked the ovarian development completely and no adult development ensued either. Both adult development and ovarian development of the isolated abdomens were stimulated by ecdysone injections. Thus, adult development and ovarian development in M. pluviale seem to be closely related.

Juvenile  Hormone  (JH)  is  considered  the  main  determinant  of  caste  in  social insects, though little is known about how this hormone acts in social wasps, especially the independent-founding species. The known relationship between JH titer and caste in the colony and we suggest a relationship among the effects of JH and the cuticular chemical profile. Therefore, this study aimed to test the hypothesis that topical application of JH to larvae of different instars alters the cuticular chemical composition of newly emerged females of Mischocyttarus consimilis (Zikán), influencing the dynamics of colony. Two techniques were used to evaluate the variation in cuticular chemical composition: Fourier transform infrared photoacoustic spectroscopy and gas chromatography coupled to mass spectrometry (GC-MS). Indeed, the application of JH did significantly alter the cuticular chemical composition of adult females that received treatment at the larval stage in comparison to control. The effects of JH were instar-dependent in that the results of topical application were significant when performed at third larval instar. Overall, these results add evidence that caste determination may, at least in part may be pre-imaginal in species of independent-founding social wasps.

AbstractTopical application of three analogues of juvenile hormone, ZR-515 (isopropyl 11-methoxy-3,7,11-trimethyldodeca-2,4-dienoate), ZR-777 (prop-2-ynyl 3,7,11-trimethyldodeca-2,4-dienoate), and JH-25 (7-ethoxy-1 (p-ethylphenoxy)-3,7-dimethyl-2-octene) to pre-diapause adults of the white pine weevil, Pissodes strobi (Peck), induced ovarian development and resorption of fat bodies. Control of this species by hormonal induction of reproductive maturity and related metabolic alterations at the onset of winter is suggested.
