Insect behavior and control techniques

The study was carried out in 2009 with the objective of knowing the diversity of ornamental species susceptible to the attack of pink cochineal hibiscus, Maconellicoccus hirsutus (Green), as well as to determine the incidence and level of insect infestation. The weekly samplings in 28 species of plants, were quantified individuals of cochineal present in 9 101 sampling sites of seven municipalities, within marginal, urban, agricultural and nursery areas. This pest was detected in 2 435 sites (26.7%), with infestation of 25.7, 0.9 and 0.1% for the low, medium and high levels, respectively. The species identified with the highest incidence of the pest were Hibiscus rosa-sinensis L. (37.4%), H. tiliaceaus Arruda (29%) and H. mutabilis L., (14.4%); For H. rosa-sinensis, the municipalities that were identified with the greatest pest-host association were Acaponeta (59.3%), Santiago Ixcuintla (44.2%) and Rosamorada (37.5%). Montanoa grandiflora Alaman ex DC and Solandra sp., Were determined as new hosts of pink hibiscus cochineal, both at infestation level 1.
