Diaspis boisduvalii Signoret, 1869 (Diaspididae: Diaspis)Nomenclatural History
- Aspidiotus palmarum; Bouché 1834: 17. misidentification (discovered by Danzig1993, 377).
- Diaspis Boisduvalii Signoret 1869d: 432-433. Type data: FRANCE: Louxembourg Botanical Garden in Paris, on orchids, by M. Boisduval. Syntypes, female, accepted valid name Notes: Types presumed lost. Illustr.
- Diaspis trinacis Colvée 1881: 19-20. Type data: SPAIN: on Thrinax sp.. Unknown type status, unknown, junior synonym Notes: Types are probably lost. Although Borchsenius (1966) treats Diaspis trinacis as an incertae sedis, we here agree with Lindinger (1912b) who synonymized it with Diaspis boisduvalii.
- Diaspis cymbidii McIntire 1889: 355. Type depository: Curitiba: Departamento de Zoologia, Setor de Ciencias Biologicas, Universidade Federal do Parana, Brazil; Sao Paulo: Museu de Zoologia, Universidade de Sao Paulo, Brazil; nomen nudum (discovered by Fernal1903b, 229). Notes: Fernald (1903b) placed Diaspis cymbidii as a placed nomen nudum of D. cattleyae which is now considered a junior synonym of D. boisduvalii.
- Aulacaspis boisduvalii (Signoret, 1869); Cockerell 1893c: 180. change of combination
- Aulacaspis cattleyae Cockerell 1899n: 30. Type data: MEXICO: in quarantine at SanFrancisco, California, on Cattleya sp., 1899, by A. Craw. Syntypes, female, Type depository: Washington: United States National Entomological Collection, U.S. National Museum of Natural History, District of Columbia, USA; junior synonym (discovered by Ferris1937, SI-32).
- Diaspis cattleyae (Cockerell, 1899); Cockerell 1902d: 59. change of combination
- Aulacaspis cymbidii (Signoret, 1869); Fernald 1903b: 229. change of combination
- Diaspis bromeliae; Bodenheimer 1949: 87. incorrect synonymy (discovered by Borchs1966, 169).
- Diaspis boisduvalii Signoret, 1869; Borchsenius 1966: 168. emendation that is justified
- Diaspis boisduvalli Signoret, 1869; Jansen & Alferink 2023: 25. misspelling of species epithet

Remarks
- Systematics: Diaspis boisduvalii is sometimes found on palms and pineapple, where it can be confused with D. bromeliae (Williams & Watson, 1988). Although Diaspis boisduvalii is considered by some (Danzig, 1993) to be a senior synonym of Diaspis coccois they are here treated as separate valid taxa. Borchsenius (1966) lists Diaspis cymbidii as an incertae sedis.
- Structure: Female scale cover opaque, circular, flat, exuvia central; male scale cover elongate, carinate with pale terminal exuvium, and associated white woolly wax. Female body creamy with dark pygidium when young, pale yellow when mature, eggs yellow. (Henderson, 2011) Prosoma usually with lateral lobes, main pygidial characters are the 6 macroducts on each side and 1 macroduct between median lobes. Median lobes forming a deep notch at apex; inner margins of each lobe diverging, serrate, and much longer than the outer margins (Williams & Watson, 1988).
- Biology: This species is known from all over the world in greenhouses, chiefly on palms, but also on other hosts like orchids and cacti (Ali, 1970). Detailed life history by Bohart (1942). The following information is taken from Bohart (1942). In the greenhouse on orchids the period from egg to egg laying females requires about 50 days; adult males require about 33 days. Eggs hatch in 5 to 7 days after being laid. The crawler stage lasts about 9 days, the second instar female about 8 days. Adult males leave the scale cover about 15 days after the first molt. Adult females may live as long as 7 months, and each produces about 200 eggs. The ratio of males to females is about 1:1. Settling occurs on all aerial parts of the plant, but there appears to be a preference for the midrib and the part of the petiole that is covered by the sheath. (Miller & Davidson, 2005).
- Economic Importance: Miller & Davidson (1990) list this insect as a serious and widespread pest. Diaspis boisduvalii is a serious pest of orchids in greenhouses in California (Gill, 1997). Boisduval scale is the most important insect pest of orchids in Florida (Dekle 1977). Bohart (1942) reports that only a few scales are necessary to cause damage. A few days after settling, a large chlorotic spot develops surrounding the body of the scale. Heavy infestations cause leaves to turn yellow and fall from the plant; entire plants are sometimes killed. Steinweden (1945) indicated that in 5 months 7 adult females on Cattleya produced 10,000 scales. The species also is reported as a minor pest of bananas, pineapple (Chua and Wood 1990), coffee (Balachowsky 1929), and coconuts (Munoz Ginarte 1937). Examples of countries or states where this species is considered to be a pest are as follows: California (Koehler 1964, Gill 1997); Colorado (Cockerell 1922); Hawaii (Kotinsky 1909); North Carolina (Baker 1994); Ohio (Steiner 1987); Zaire (Balachowsky 1929); West Indies (Ballou 1922); Argentina (Chiesa Molinari 1948); Spain and Portugal (Efimoff 1937); French West Africa and Togo (Mallamaire 1954); England (Miles and Miles 1935); Mauritius (Moutia and Mamet 1947); Bulgaria (Tzalev 1964); Trinidad (Urich 1893); Cuba (Munoz Ginarte 1937); France (Panis and Pinet 1998); Czechoslovakia (Zahradnik 1990a); Canary Island (Gomez-Menor Ortega 1958); and Sierra Leone (Hargreaves 1937). Panis and Pinet (1998) discuss the biological control of this pest in greenhouses using the parasite Coccidencyrtus malloi Blanchard. Beardsley and González (1975) consider this scale to be one of 43 serious armored scale pests, and Miller and Davidson (1990) consider it to be a serious world pest. (Miller & Davidson, 2005).
