Humidity Reaction

1. Removal of both antennae of the mealworm beetle, Tenebrio molitor, completely abolishes the animal's reaction to humidity. Removal of both maxillary palps has no effect on the reaction. 2. The quantitative distribution of the five types of sensillae present along the eleven segments of the antenna is described. Two of these types occur also on the maxillary palps. 3. Progressive symmetrical amputation of antennal segments leads to a gradual reduction of the humidity reaction to zero; there is a reaction with four segments remaining on each side and no reaction when only three segments remain. 4. Asymmetrical amputation of the more basal segments shows that humidity receptors are nevertheless present on these and that a threshold number of sensillae must be left in action before a reaction occurs. 5. The experimental work, taken in combination with observations in the distribution of sensillae, shows that the pit peg organs are hygro-receptive. Either the peg organs or the bristles or both are hygro-receptive as well. It is, however, unlikely that the bristles are hygro-receptive. 6. Experimental work on the locomotory activity of this beetle shows that the conclusions are not invalidated by any general ill effects of amputation of antennae. 7. It is suggested that the hygro-receptors function hygroscopically.

Suppressors Of Cytokine Signaling

Suppressors of cytokine signaling (SOCS) influence cytokine and growth factor signaling by negatively regulating the Janus kinase (JAK)-signal transducers and activators of transcription (STAT) pathway to maintain homeostasis during immune responses. However, functional characterization of SOCS family members in invertebrates is limited. Here, we identified and evaluated three SOCS genes (type I sub-family) in the mealworm beetle Tenebrio molitor. The full-length open reading frames (ORFs) of TmSOCS5, TmSOCS6, and TmSOCS7 comprised of 1389, 897, and 1458 nucleotides, encoding polypeptides of 462, 297, and 485 amino acids, respectively. The SH2 and SOCS box domains of the TmSOCS C-terminal region were highly conserved. Phylogenetic analysis revealed that these SOCS genes were clustered within the type I subfamily that exhibits the highest amino acid identity with Tribolium castaneum SOCS genes. Contrary to TmSOCS7 expression, the expression levels of TmSOCS5 and TmSOCS6 were lower in the larval, pupal, and adult stages. In larvae and adults, the expression levels of TmSOCS5 and TmSOCS6 were highest in the hemocytes and ovaries, respectively. SOCS transcripts were also highly upregulated in the hemocytes of T. molitor larvae within 3–6 h post-infection with the fungus Candida albicans. Collectively, these results provide valuable information regarding the involvement of TmSOCS type-I subfamily in the host immune response of insects.
