Biology of blepyrus clavicornis (compere) (hymenoptera: encyrtidae), a parasitoid of pseudococcus viburni (signoret) (hemiptera: pseudococcidae). Repositório Alice
SILVA, V. P. da; GARCIA, M.; BOTTON, M..
Mealybugs (Hemiptera: Pseudococcidae) are common pests in fruitproduction(Franco et al., 2009; Daane et al., 2012). The obscure mealybug Pseudococcus viburni (Signoret) is a cosmopolitan and polyphagous species found in 56 countries. It feeds on members of nearly 90 plant families and 240 genera (García et al., 2016), and is one of the main pest species of vineyards (Vitis spp., Vitaceae) in Brazil as well as other countries of the Americas (Correa et al., 2012; Daane et al., 2012; Pacheco da Silva et al., 2014). P. viburni also attacks other plants of economic importance, such as apples (Rosaceae) and pears (Rosaceae) (Ciampolini et al., 2002; Dapoto et al., 2011). It feeds on the leaves, trunks, cordons, canes, fruits and roots of host plants. Similarly...

Biology of Blepyrus clavicornis (Compere) (Hymenoptera: Encyrtidae), a parasitoid of Pseudococcus viburni (Signoret) (Hemiptera: Pseudococcidae) Rev. Bras. entomol.
Silva,Vitor Pacheco da; Garcia,Mauro; Botton,Marcos.
Abstract Encyrtids (Hymenoptera: Encyrtidae) are the most important and diverse group of natural enemies of mealybugs (Hemiptera: Pseudococcidae). Blepyrus clavicornis (Compere) is the most common parasitoid associated with Pseudococcus viburni (Signoret) in the Serra Gaúcha region, Brazil. We conducted laboratory studies to assess the development time, sex ratio, adult longevity, host stage selection for parasitism, and effect of food on the longevity of adult females of B. clavicornis. The experiments were conducted in a climate chamber at 25 ± 1 °C, 70 ± 10% RH and 12:12 L:D photoperiod. The solitary parasitoid B. clavicornis parasitized third-instar and adult female stages of P. viburni. The development time was more than 30 days (31.75 ± 0.38 for...

Effect of host plants on the development, survivorship, and reproduction of Pseudococcus viburni (Hemiptera: Pseudococcidae). Repositório Alice
SILVA, V. C. P. da; NONDILLO, A.; GALZER, E. C. W.; BOTTON, M..
Abstract The obscure mealybug Pseudococcus viburni (Signoret) (Hemiptera: Pseudococcidae) is one of the most important damaging mealybugs in vineyards worldwide and in South American temperate fruit production. The life history of P. viburni on 3 fruit species was studied under laboratory conditions. Leaves of apple Malus domestica (Borkh.), persimmon Diospyros kaki L., and grapevine Vitis labrusca L., were used as host plants. Mealybugs were able to develop, survive, and reproduce on all 3 hosts; however, persimmon and grape leaves were most suitable for P. viburni development and reproduction. The cumulative development time (nymph to adulthood) ranged from about 35 d on persimmon and grape leaves to 40.87 ± 0.53 d on apple leaves for females, and from...
