Life History of <I>Paracoccus marginatus</I> (Hemiptera: Pseudococcidae) on Four Host Plant Species Under Laboratory Conditions

Abstract

Life history of the mealybug, Paracoccus marginatus Williams and Granara de Willink, on three ornamental plants [Hibiscus rosa-sinensis L., Acalypha wilkesiana (Muell.-Arg.), and Plumeria rubra L.] and one weed species (Parthenium hysterophorus L.) was studied under laboratory conditions. Mealybugs were able to develop, survive, and reproduce on all four hosts; however, there were differences in the life history parameters. Adult females that developed on acalypha and parthenium emerged approximately 1 d earlier than those that developed on hibiscus and plumeria. Adult males had a longer developmental time on plumeria than on the other hosts. Survival of first- and second-instar nymphs and cumulative adult survival were lowest on plumeria. Longevity was not affected by hosts for males and females and averaged 2.3 +/- 0.1 and 21.2 +/- 0.1 d, respectively. On plumeria, 58.9 +/- 1.7% of the adults were females, which was a higher female percentage than on the other hosts. No egg production occurred in virgin females. Prereproductive and reproductive periods of the females were not affected by hosts and averaged 6.3 +/- 0.1 and 11.2 +/- 0.1 d, respectively. Mean fecundity of 186.3 +/- 1.8 eggs on plumeria was lower than on the other three plant species. Life history parameters of P. marginatus on hibiscus, acalypha, plumeria, and parthenium show its ability to develop, survive, and reproduce on a wide variety of plant species.

Influence of different plants substrates on development and reproduction for laboratory rearing of Pseudococcus calceolariae (Maskell) (Hemiptera: Pseudococcidae)

“…Female P. kraunhiae reared on broad bean seeds laid an average of 965 eggs per female at 24 ºC (narai and Murai, 2002). Fertility values reported for other species are lower than those obtained for P. calceolariae in this study and include, for example, 72 % for M. hirsutus on hibiscus cuttings at 25 ºC (Chong et al, 2008) and 82.2 -83.5 % for P. marginatus on different substrates at 25 ºC (Amarasekare et al, 2008).…”

“…generational times reported for other species reared in different substrates are in general shorter than those obtained for P. calceolariae here. This is the case for Paracoccus marginatus (24.4 -25.5 days at 25 ºC, depending on the substrate; Amarasekare et al, 2008), Planococcus ficus (28.1 days at 25 ºC, reared on grapevines; Walton and Pringle, 2005), Maconellicoccus hirsutus (32.4 days at 25 ºC, reared on hibiscus cuttings; Chong et al, 2008) and Planococcus kraunhiae (37.8 days reared on broad bean seeds; narai and Murai, 2002).…”

“…to study the developmental biology (e.g. Arai, 1996;Walton and Pringle, 2005;Amarasekare et al, 2008), their susceptibility to pesticides, or for molecular studies (e.g. Beuning et al, 1998).…”

“…Menurut Amarasekare et al (2008), perbedaan siklus hidup serangga pada beberapa tanaman inang dapat disebabkan oleh faktor nutrisi, senyawa alelokimiawi, dan struktur fisik daun tanaman inang. Spesies tanaman yang berbeda menyediakan kualitas nutrisi dan unsur pokok kimia yang berbeda.…”

Laboratory Studies on the Development and Life Table Parameters of Planococcus citri (Risso) (Hemiptera, Pseudococcidae) at Different Temperatures

“…However, no significant difference in adult longevity of males and females of the mealybug, Paracoccus marginatus reared on different hosts. Mean longevity of adult males and females kept at 25 ºC was 2.3 day and 21.2 day, respectively (Amarasekare et al, 2008). Adult longevity of the citrus mealybug, P. citri at three different constant temperatures (18, 24 and 30 o C) on citrus was 17.3, 13.1and 11.7 days, respectively (Ahmed and AbdRabou, 2010).…”
