| maternal effects in the soft scale insect saissetia coffeae (hemiptera: coccidae). | 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 (he ... | 2004 | 15612288 |
| local maladaptation in the soft scale insect saissetia coffeae (hemiptera: coccidae). | 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 ... | 2006 | 17089970 |
| scale insects (hemiptera: coccoidea) associated with arabica coffee and geographical distribution in the neotropical region. | coffee is one of the most important brazilian agricultural commodities exported, and minas gerais and espírito santo states are the main coffee producers. scale insects are important coffee pests, and 73 species of cerococcidae (3), coccidae (18), diaspididae (6), eriococcidae (1), ortheziidae (3), pseudococcidae (21), putoidae (2) and rhizoecidae (19) have been associated with roots, branches, leaves, flowers and fruits of arabica coffee in the neotropics. eight species were found associated wi ... | 2018 | 29236860 |
| efficacy of five volatile oils and their mixtures against the soft scale insect, saissetia coffeae (walker) (hemiptera: coccidae) infesting the sago palm, cycas revoluta in alexandria, egypt. | five tested plant volatile oils and their mixtures were evaluated for controlling the coccid, saissetia coffeae (walker) on growing sago palms cycas revoluta in antoniades public gardens, alexandria, egypt. the tested volatile oils at concentration rates of 0.5, 1 and 1.5% (v/v) were: camphor 20%, dill 20%, rose 30%, peppermint 20% and clove 30% (v/v). their mixtures were : camphor/peppermint, camphor/rose at a rate of 1:1, camphor/rose/peppermint at 1:1:2 rate and camphor/rose/dill at 2:1:1 rat ... | 2010 | 21539257 |
