local maladaptation in the soft scale insect Saissetia coffeae hemiptera coccidae
Evolution, 2006Co-Authors: Brian W SpitzerAbstract:Local adaptation has often been documented in herbivorous insects. The potential for local maladaptation in phytophagous insects, however, has not been widely considered. I performed a two-generation reciprocal cross-transplant experiment with the generalist soft scale insect Saissetia coffeae (Hemiptera: Coccidae) on two common species of host plants in rain forest habitat in Costa Rica. In this system, S. coffeae showed significant local maladaptation at the level of the host species. Lineages originally collected from Witheringia enjoyed a strong advantage over those collected from Lomariopsis when both sets of lineages were placed on Lomariopsis; however, when both sets of lineages were raised on Witheringia, their fitnesses were statistically indistinguishable. While some aspects of the biology of S. coffeae may impair its ability to adapt to local selection pressures, scale insects are often locally adapted on fine spatial scales, and local maladaptation is therefore especially surprising. Other documented cases of local maladaptation in parasites appear to be due to evolution on the part of the host. The possibility that hosts or natural enemies may place local genotypes at a disadvantage, producing a pattern of local maladaptation, is one that deserves more consideration in the context of plant-insect interactions.

maternal effects in the soft scale insect Saissetia coffeae hemiptera coccidae
Evolution, 2004Co-Authors: Brian W SpitzerAbstract:Effects of maternal environment on offspring performance have been documented frequently in herbivorous insects. Despite this, very few cases exist in which exposure of parent insects to a resource causes the phenotype of their offspring to be adjusted in a manner that is adaptive for that resource, a phenomenon called adaptive transgenerational phenotypic plasticity. I performed a two-generation reciprocal cross-transplant experiment in the field with the soft scale insect Saissetia coffeae (Hemiptera: Coccidae) on two disparate host plant species in order to separate genetic effects from possible transgenerational plasticity. Despite striking differences in quality between host species, maternal host had no effect on overall offspring performance, and I detected no "acclimatization" to the maternal host species. However, there was a significant negative association between maternal and offspring development times, with potentially adaptive implications. Furthermore, offspring of mothers reared in an environment where scale densities were higher and scales were more frequently killed by fungi were significantly less likely to suffer from fungal attack than were offspring of mothers reared in an environment where densities were low and fungal attack was rare. Although S. coffeae does not appear to alter offspring phenotype to increase offspring fitness on these two distinct plant species, it does appear that offspring phenotype may be responding to some subtler aspects of maternal environment. In particular, the possibility of induced transgenerational prophylaxis in S. coffeae deserves further investigation.

Coccophagus scutellaris (Hymenoptera: Aphelinidae): A Highly Effective Biological Control Agent of Soft Scale Insects (Hemiptera: Coccidae) in Egypt
Psyche: A Journal of Entomology, 2011Co-Authors: Shaaban Abd-rabouAbstract:About 953000 individuals of the cosmopolitan parasitoid, Coccophagus scutellaris (Dalman) (Hymenoptera: Aphelinidae), were released and evaluated during 2009-2010 for the control of the following soft scale insects (Hemiptera: Coccidae) infesting the following economic crops in Egypt: Ceroplastes rusci on citrus in Beni Seuf, Ceroplastes floridensis Comstock on citrus in Gharbiya, Coccus hesperidum L. on guava in Giza, Pulvinaria floccifera (Westwood) on mango in Sharqiya, Pulvinaria psidii Maskell on mango in Ismailia, Saissetia coffeae (Walker) on olive in Marsa Matruh, and Saissetia oleae (Oliver) on olive in the Northern Coast. The population of C. scutellaris showed a significant correlation with the build up of the population of the soft scale insects population in all of the release sites studied. The maximum rate of parasitism of the other species of parasitoids associated with soft scale insects at the release sites decreased after the release of C. scutellaris.

Importation, colonization and establishment of Coccophagus cowperi Gir. (Hymenoptera: Aphelinidae) on Saissetia coffeae (Walk.)(Homoptera: Coccidae) in Egypt
Journal of Pest Science, 2005Co-Authors: Shaaban Abd-rabouAbstract:The hemispherical soft scale, Saissetia coffeae (Walker) (Homoptera: Coccidae), is one of the most important pests attacking olive trees in Egypt. During the period 2001–2003, a total of about 300,000 individuals of the parasitoid Coccophagus cowperi Girault (Hymenoptera: Aphelinidae), obtained from India, was released at 35 sites for the biological control of S.coffeae on olive trees in Egypt. The maximum parasitism rates reached 53 and 62%, while average parasitism rates were 17.2 and 30.8% in the Marsy Mattrouh and El-Arish locations, respectively. These results indicate establishment of this parasitoid on this important economic plant in Egypt.

Scale insects (Hemiptera: Coccoidea) associated with avocado crop, Persea americana Mill. (Lauraceae) in Valle del Cauca and neighboring departments of Colombia
2016Co-Authors: Kondo Takumasa, Muñoz, Jazmín AdrianaAbstract:Scale insects (Hemiptera: Coccoidea) of avocado, Persea americana Mill. (Lauraceae) were collected in the State of Valle del Cauca, Colombia. The study was conducted for one year, during October 2008–October 2009. As a result of this study, 34 scale insect species in seven families (Coccidae, Diaspididae, Kerriidae, Margarodidae, Monophlebidae, Pseudococcidae and Putoidae) were collected. Together with previous records, the number of scale insects collected on avocado in Colombia increased to 44 species and to 137 species worldwide. Species commonly collected on avocado in Colombia include Hemiberlesia cyanophylli (Signoret), Pseudoparlatoria parlatorioides (Comstock) (Diaspididae), Ceroplastes rubens Maskell, Coccus hesperidum L., Protopulvinaria pyriformis (Cockerell), Pulvinaria psidii Maskell, Saissetia neglecta De Lotto (Coccidae) and Ferrisia williamsi Kaydan and Gullan (Pseudococcidae).
