Ross] Mottled body (Mt) is a mutant of the German cockroach, Blattella germanica (L.), which is characterized by extensive color variegation on the surface of the body. Irregular light patches appear in the integument of wild-type black color. Mottling is more conspicuous on abdominal segments than on thoracic segments. The character is clearly observed in the nymphal stage but also can be seen on the small dorsal tergites of adults. Expression of mottling is variable. The trait is mostly maternally inherited, and cytoplasmic factor(s) may be involved. A method for judging the degree of mottling was established. Degree of mottling was scored on the surfaces from 1st to 3rd thoracic and 1st to 7th abdominal segments. Mottling patterns did not change during late nymphal development. Mottling expression did not decrease from the Mt stock to the F1 (Mt female × wild-type male), and F2 (F1 Mt female × wild-type male). Mottling patterns were often different between left and right sides. Patterns were often discontinuous across the median line of the body and sometimes one side was mottled and the other side almost wild-type color. Separate scoring between left and right surfaces and also between dorsal and ventral surfaces revealed that the degree of mottling was more correlated dorsoventrally than laterally. This suggests that mottling patterns were determined before dorsal closure during embryogenesis and are influenced by the shape peculiar to cockroach embryos packed in the ootheca, which is broad dorsoventrally and compressed laterally. © 1996 Entomological Society of America Genetics nationallicence German cockroach nationallicence mosaicism nationallicence cytoplasmic inheritance nationallicence Tanaka Akira Department of Biology, Nara Women's University, Nara 630, Japan. aut Ross Mary H. 2Department of Entomology, Virginia Polytechnic Institute & State University, Blacksburg, VA 24061. aut Annals of the Entomological Society of America Oxford University Press 89/1(1996-01-01), 129-136 0013-8746 89:1<129 1996 89 aesa https://doi.org/10.1093/aesa/89.1.129 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/aesa/89.1.129 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Tanaka Akira Department of Biology, Nara Women's University, Nara 630, Japan aut NATIONALLICENCE 700 1- Ross Mary H. 2Department of Entomology, Virginia Polytechnic Institute & State University, Blacksburg, VA 24061 aut NATIONALLICENCE 773 0- Annals of the Entomological Society of America Oxford University Press 89/1(1996-01-01), 129-136 0013-8746 89:1<129 1996 89 aesa Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
