| development and life table parameters of phenacoccus madeirensis green (hemiptera: pseudococcidae) on four ornamental plants. | the development, reproduction, and life table parameters of the phenacoccus madeirensis green (hemiptera: pseudococcidae) on four ornamental plant species, namely pelargonium zonale (geraniaceae), hibiscus rosa-sinensis, hibicus syriacus (malvaceae), and cestrum nocturnum (solanaceae) were investigated under controlled conditions (25 ± 2°c, 60 ± 10% r.h., and 16 h photophase). life table data were analyzed by using an age-stage two-sex life table. the shortest total immature developmental time o ... | 2016 | 26951150 |
| description of a new species of anagyrus howard (hymenoptera: chalcidoidea: encyrtidae), a promising biological control agent of the invasive madeira mealybug, phenacoccus madeirensis green (hemiptera: sternorrhyncha: pseudococcidae). | anagyrus amnestos sp. n. (hymenoptera: encyrtidae), a promising parasitoid of the invasive madeira mealybug, phenacoccus madeirensis green (hemiptera: pseudococcidae), is described based on material collected from india. this parasitoid was identified as anagyrus sp. nov. nr. sinope noyes & menezes in recent literature, and was initially collected in georgia, usa. it was found to be a specific parasitoid of the madeira mealybug and its biological attributes and potential as a biological control ... | 2013 | 26176096 |
| identification of mealybug pest species (hemiptera: pseudococcidae) in egypt and france, using a dna barcoding approach. | pseudococcidae (mealybugs) is a large taxonomic group, including a number of agronomic pests. taxonomic identification of mealybug species is a recurrent problem and represents a major barrier to the establishment of adequate pest management strategies. we combined molecular analysis of three dna markers (28s-d2, cytochrome oxidase i and internal transcribed spacer 2) with morphological examination, for the identification of 176 specimens collected from 40 mealybug populations infesting various ... | 2012 | 22360997 |
| identification and synthesis of the sex pheromone of the madeira mealybug, phenacoccus madeirensis green. | two components were identified from aeration extracts of the virgin female madeira mealybug, phenacoccus madeirensis as trans-(1r,3r)-chrysanthemyl (r)-2-methylbutanoate and (r)-lavandulyl (r)-2-methylbutanoate (with a ratio of 3:1) by a combination of gas chromatography retention time matches, mass spectrometry, and microchemical tests. the structures and chirality of the compounds were confirmed by comparing with synthetic compounds. the synthetic trans-(1r,3r)-chrysanthemyl (r)-2-methylbutano ... | 2009 | 19529970 |
| chirality and bioactivity of the sex pheromone of madeira mealybug (hemiptera: pseudococcidae). | two compounds (trans-1r,3r-chrysanthemyl r-2-methylbutanoate and r-lavandulyl r-2-methylbutanoate) identified from aeration extracts of virgin female madeira mealybug, phenacoccus madeirensis green (hemiptera: pseudococcidae), were synthesized and tested in field bioassays in northern taiwan over a 1-mo period. in total, 1,492 male p. madeirensis were captured in sticky traps. our results showed that 1 microg of synthetic trans-1r,3r-chrysanthemyl r-2-methylbutanoate released from a plastic tube ... | 2011 | 21735899 |
