“…Mealybugs (Hemiptera: Pseudococcidae) are important plant pests worldwide (McKenzie 1967;Williams 1985;Williams & Granara de Willink 1992;Miller et al 2002Miller et al , 2005b. Their feeding may cause leaf yellowing, defoliation, reduced plant growth, and in some cases death of plants.…”

Three mealybug (Hemiptera: Pseudococcidae) plant pest species: Dysmicoccus boninsis (Kuwana), Phenacoccus solenopsis Tinsley, and Pseudococcus viburni (Signoret), are recorded for the first time in the state of Espírito Santo, Brazil. This is the first record of Phenacoccus solenopsis in Brazil, where it was found infesting tomato plants. The species Antonina graminis (Maskell), a common pest of Bermuda grass, and Dysmicoccus brevipes (Cockerell), a major pest of pineapple, also were encountered. Key words: Antonina graminis, Dysmicoccus boninsis, Dysmicoccus brevipes, Phenacoccus solenopsis, Pseudococcus viburni, Solanum lycopersicum Uma nova praga do tomateiro e outros registros de cochonilhas-farinhentas (Hemiptera: Pseudococcidae) no Espírito Santo, BrasilResumo: São registradas pela primeira vez a ocorrência das cochonilhas-farinhentas (Hemiptera: Pseudococcidae) Dysmicoccus boninsis (Kuwana), Phenacoccus solenopsis Tinsley, e Pseudococcus viburni (Signoret) no estado do Espírito Santo. Destaca-se que o registro de Phenacoccus solenopsis, encontrada no tomateiro, é o primeiro no Brasil. Também foram encontradas em capim Bermuda a espécie Antonina graminis (Maskell) e em abacaxi e abóbora a espécie Dysmicoccus brevipes (Cockerell), ambas já relatadas no estado do Espírito Santo.

“…The morphological analysis revealed that the phenotype of P. calceolariae used in this study corresponds to the most common one present in Australia and new Zealand, as the four parameters measured were well within the range reported for this phenotype (Cox, 1987;Williams, 1985), and were different from the phenotype described originally as P. similans and later synonymized with P. calceolariae (Charles et al, 2000) (Table 1).…”

“…), to name the most important (Artigas, 1994;Ripa and Larral, 2008). Pseudococcus calceolariae is a cosmopolitan species, and possible native to east Australia (Williams, 1985; Wil-liams and granara de Willink, 1992). It was detected for the first time in Chile around 1925, and its area of distribution in the country ranges now from the extreme north (Arica) to the region of the Araucanía, in southern Chile (Artigas, 1994).…”

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

T. Zaviezo, E. Cadena, M. F. Flores, and J. Bergmann. 2010. Influence of different plants substrates on development and reproduction for laboratory rearing of Pseudococcus calceolariae (Maskell) (Hemiptera: Pseudococcidae). Cien. Inv. Agr. 37(3): 31-37. The citrophilus mealybug, Pseudococcus calceolariae, is a polyphagous pest that has a major impact on fruit crops in central Chile, and is of quarantine importance for many markets. To study many control alternatives, it is important to develop efficient rearing protocols. The objective of this work was to determine mealybug development on three different plant substrates: sprouted potatoes, lemon fruits and Butternut squash. Insects were inoculated on the substrates, maintained at 25°C and in total darkness until completing their development. Every one to 4 days, advancement on the development was checked by counting the exuvia. Mean developmental time for each stage, adult longevity, fecundity and fertility were determined. Preimaginal developmental time was similar for females and males, but it differed among plant substrates. For females, preimaginal development was about nine days shorter on potatoes, as compared to butternut squash or lemons, and for males about 12 days longer in squash than on the other two substrates. The preoviposition period was significantly longer in squash and consequently, a longer generational time resulted. Female adult longevity was similar in all substrates, around 31 days, and for males it was 6 days in potatoes and lemons and 4 days on squash. Female fecundity was similar in potatoes and squash, and lower on lemons. Egg fertility was significantly higher on potatoes. Parthenogenetic reproduction was not observed. Therefore, the three substrates were adequate for rearing P. calceolariae, but the shortest developmental time and highest fecundity and fertility were obtained on sprouted potatoes.

“…Scale insects often have one or more specialized setae on or near the terminus of the leg called digitules. Most scale taxonomists use the term based on setal shape and position on the leg (i.e., it is differentiated from nearby setae in some way, most often enlarged and with an enlarged apex and is near or at the apex of the leg) (Williams 1985, Hodgson 1994, Hardy et al 2008). If a seta occurs on the claw it is considered to be a digitule regardless of the shape.…”

Rediscovering digitules in Aphidomorpha and the question of homology among Sternorrhyncha (Insecta, Hemiptera)

We explore and expand on the morphological term digitule. The term was originally proposed for toe-like setae on a species of Phylloxera Boyer de Fonscolombe, 1834 (Hemiptera, Sternorrhyncha, Aphidomorpha) by Henry Shimer, an American naturalist. While it is standard terminology in scale systematics (Hemiptera, Sternorrhyncha, Coccidomorpha), the term digitule was ignored by aphid specialists despite being the original taxon for which the term was described. Similar setae occur on many arthropod groups, so the homology is poorly understood even within any superfamily of Hemiptera. We provide the etymology of the term, a proposed explanation for why it was used among scale taxonomists and not aphid taxonomists, and discuss briefly options to progress beyond the confusion between terminology for morphology and homology in Sternorrhyncha.
