Coccus trichodes Anderson  

Coccus trichodes Anderson, 1787e: 4   ; 1787g: 2; 1788a: 4; 1788b: 20, 25; Signoret, 1877: 625; Fernald, 1903: 327.

In letter No. 3, Anderson (1787a: 5) referred to a`viviparous insect covered with white Farina on the Robinia Grandi X   ora, or Agaty Jumbo of the Tamuls on the Psidium Guajava   and Hibiscus Rosa Sinensis   with a nipple between the two foremost pair of legs, a drawing of which is enclosed No. 8’. In the later version of this letter, Anderson (1788b: 3) again referred to ®gure 8 but only to the species on Robinia mitis   (presumably altered from R. grandi   X ora) and on H. rosa sinensis   . He referred to a diOEerent insect on Psidium guajava   and Hibiscus rosa sinensis   . After placing branches of the guava tree on Opuntia   plants, the guava insects multiplied on the cactus so that the leaves were entirely covered with a white hairy scurf. Anderson’s ®gure 9 refers to this insect and his ®gure 10, the ¯y, is a fairly good representation of an adult male mealybug and is accompanied by a description discussing two very remarkable hairs being perfectly opaque and white and only a little longer than the ¯y. He described ®gure 11 as a caterpillar but this is probably a chrysopid larva.

The name Coccus trichodes   , or guava Coccus   , ®rst appeared in the 11th letter ( Anderson, 1787e). Host plants listed are Psidium Guajava   , Annona Squamosa   , Solanum Lycopersicum   , Hibiscus Rosa Sinensis and Phasioli   [5 Phasiolus   ].

There is no doubt that the name Coccus trichodes   is valid and that it refers to a mealybug of the family Pseudococcidae   . Although the species is probably Maconellicoccus hirsutus (Green)   , there is no positive evidence of its correct identity and it should be left under its original name.
