The insect male accessory gland (MAG) is an internal reproductive organ responsible for the synthesis and secretion of seminal fluid components, which play a pivotal role in the male reproductive strategy. In many species of insects, the effective ejaculation of the MAG products is essential for m...
The proportion of both male morphs was recorded for each cross. Parents of C. berlesei were isolated individually from the population at the stage of quiescent protonymphs (an instar preceding the tritonymphal stage at which a developmental switch occurs). Since such a procedure gives a very ...
which were consistent with morphological changes of wing buds.These results indicate that the 3rd instar nymph is the critical stage of wing bud differentiation in males.Furthermore,through pathway enrichment analysis of DEGs and WGCNA,it revealed that the neuroactive ligand-receptor interaction,Ras ...
To test whether these phenotypic differences correlate with variation in gene expression, we sequenced the leg transcriptomes of males and females from these lines at the 5th nymphal instar – the developmental stage where we observed a burst of growth [40]. If a strict correlation existed between...
In this study, the two hypotheses proposed for the evolution of male mate choice (i.e., cannibalism avoidance and fecundity preference) were examined with the praying mantid Tenodera angustipennis. Both the adult and nymph of this species engage in cannibalism, as revealed by an enclosure study...
neotestacea harbors a non-male-killing Spiroplasma strain (also within the poulsonii clade) that inhibits growth of Howardula aoronymphium, a parasitic nematode of adult hemocoel (Jaenike et al., 2010b). Thus, assuming the same mechanism is responsible for growth inhibition of the two types...
Marchalina hellenica is univoltine and undergoes three female and four male nymphal instars [1,13]. Adult females, which bear 11-segmented antennae and lack mouthparts, usually appear on the branches of pine trees during April, where they oviposit a mean of 262 eggs in woolly ovisacs [1,...
