Pentatomid bug

In that respect, it is worth noting that in the sperm of the pentatomid bug Murgantia histrionica branched mitochondria fuse gradually to form a cluster of interlocked networks (Pratt 1968), a fusion that was seen as a mechanism to give the mitochondrial DNA a chance to recombine. Thus, an appreciable quantity of recombined paternal mitochondrial DNA is assumed to be transferred to the fertilized egg (Nass et al. 1965 Baccetti Afeelius 1976). However, it is often critical to detect an influence of the paternal mitochondrial DNA in a fertilized egg or embryo (Baccetti Afeelius 1976). Thus, by making a cross-fertilization between two Xenopus toad species, and using molecular hybridization techniques, Dawid (1972) failed to find any... 

The pheromone chemistry of A. hilare has been studied in detail, using both laboratory (vertical Y-tube) and field bioassays [75]. In Y-tube bioassays, mature females were attracted by male odors, but males were not attractive to other males, and females were not attractive to either sex. Males produced (-)-cis-Z-BAE and (-)-frazzs-Z-BAE in a -19 1 ratio, and other compounds in the extracts were not active. The 19 1 blend was more attractive to females than other ratios, and the individual components were not attractive, indicating that both compounds were required. Females were attracted to the synthetic blend in field cage trials [75],but as with most other phytophagous pentatomids,few bugs were caught in pheromone-baited traps (J.G. Millar and H.M. McBrien, unpublished data).
