Results provide further evidence suggesting leptin is a MT growth-promoting factor and the inhibition of leptin signaling could serve as a potential adjuvant therapy for treatment of breast cancer and/or provide a new target for the designing strategies to prevent MT development.
Manuka Oil and Phoebe Oil are Attractive Baits for Xyleborus glabratus (Coleoptera: Scolytinae), the Vector of Laurel Wilt

Manuka oil was equally attractive as redbay wood to X. glabratus, but increasing release rates >10-fold did not enhance its activity, and phoebe oil, an extract of Brazilian walnut, was also attractive.

Male Roptrocerus xylophagorum (Ratzeburg) (Hymenoptera: Pteromalidae) exhibited courtship and mating behaviors including wing fanning, antennation, mounting, and copulation attempts when exposed to glass bulb decoys coated with a whole-body extract of females in hexane, acetone, or methanol, supporting the hypothesis that the pheromone was composed of one or more cuticular hydrocarbons.
Attraction of the Bark Beetle Parasitoid Roptrocerus xylophagorum (Hymenoptera: Pteromalidae) to Host-Associated Olfactory Cues

The importance of the complete host/plant complex for attraction of R. xylophagorum to its host’s habitat is shown and a possible role for particular odors from uninfested host plant tissue in directing foraging parasitoids away from locations with few or no hosts is suggested.
Ablation of leptin signaling disrupts the establishment, development, and maintenance of endometriosis-like lesions in a murine model.

It is confirmed that leptin signaling is a necessary component in lesion proliferation, early vascular recruitment, and maintenance of neoangiogenesis in a murine model of endometriosis.
Electrophysiological and Behavioral Responses of Dendroctonus frontalis (Coleoptera: Curculionidae) to Volatiles Isolated from Conspecifics

- 1 December 2005
Olfactory sensitivity of the southern pine beetle, Dendroctonus frontalis Zimmermann, to compounds isolated from the mid/hindguts of newly emerged conspecific adults was assayed with coupled gas chromatography-electroantennographic detection to indicate that the majority of the eight compounds were produced in greater quantities by newly emerged beetles than ones attacking pine bolts.

Histological studies show high fine root mortality rate in the hot burn treatment, and Decline syndrome is complexed by root pathogens, soil factors, root damage and dysfunction.
Semiochemicals from Fungal Associates of Bark Beetles May Mediate Host Location Behavior of Parasitoids
- B. Sullivan, C. Berisford

- 1 April 2004
Whereas the laboratory olfactometer data suggest that bark beetle fungal associates may enhance attraction of some parasitoids, bioassays with associate-free hosts indicate that associate-produced are not required for short-range host location and parasitization.
Odor Perception in the Bark Beetle Parasitoid Roptrocerus xylophagorum Exposed to Host Associated Volatiles

Investigation of specific odors utilized as host location cues by the bark beetle parasitoid, Roptrocerus xylophagorum, originating from the southeastern United States found females were attracted to steam distillates and males failed to respond.
