| mortality of leishmania major in phlebotomus papatasi caused by plant feeding of the sand flies. | the plant feeding of phlebotomus papatasi and the effects of plant diets on the leishmania major infections were investigated. plant-fed flies had small free particles and membranous shreds in their gut that were stained by calcofluor as cellulosic plant tissues. they were found in 34.0% of the female and 14.3% of the male sand flies following feeding on the caper plant (capparis spinosa). no plant residues were found in 54 females that had been fed on plant-derived honeydew secretions of aphis ... | 1994 | 8304569 |
| role of two insect growth regulators in integrated pest management of citrus scales. | portions of two commercial citrus orchards were treated for two consecutive years with buprofezin or three consecutive years with pyriproxyfen in a replicated plot design to determine the long-term impact of these insect growth regulators (igrs) on the san joaquin valley california integrated pest management program. pyriproxyfen reduced the target pest, california red scale, aonidiella aurantii maskell, to nondetectable levels on leaf samples approximately 4 mo after treatment. pyriproxyfen tre ... | 2006 | 16813306 |
| role of imidacloprid in integrated pest management of california citrus. | portions of three commercial citrus orchards were treated for 1 yr with foliar imidacloprid or for 2 yr with a systemic formulation in a replicated plot design to determine the impact of this neonicotinoid on the san joaquin valley california citrus integrated pest management (ipm) program. foliar-applied imidacloprid had little effect on california red scale, aonidiella aurantii (maskell); cottony cushion scale, icerya purchasi maskell; or citrus red mite, panonychus citri (mcgregor), populatio ... | 2008 | 18459411 |

| rapid assessment of insect fauna based on local knowledge: comparing ecological and ethnobiological methods. | the rapid assessment of biodiversity making use of surveys of local knowledge has been successful for different biological taxa. however, there are no reports on the testing of such tools for sampling insect fauna. the present study aimed to evaluate the efficiency of different ethnobiological techniques for rapid sampling of insect fauna. | 2016 | 26932264 |
| abundance of icerya purchasi (hemiptera: margarodidae) and its parasitoid cryptochaetum iceryae (diptera: cryptochaetidae) in argentina blueberry crops. | icerya purchasi maskell is a polyphagous scale pest of ornamentals and several other crops. it has two natural specialist enemies that maintain its populations at low levels: rodolia cardinalis (mulsant) and cryptochaetum iceryae (williston). i. purchasi was recently observed in blueberry crops (vaccinium corymbosum l.) in argentina. seven blueberry fields located in different agricultural landscapes were sampled from july 2006 to september 2008. i. purchasi was present only in the citrus areas ... | 2009 | 19389286 |

| conserving vedalia beetle, rodolia cardinalis (mulsant) (coleoptera: coccinellidae), in citrus: a continuing challenge as new insecticides gain registration. | the effects of insecticides used for california citrus pest management were evaluated using larval and adult stages of vedalia beetle, rodolia cardinalis (mulsant). this predatory beetle is essential for control of cottony cushion scale icerya purchasi (williston) (homoptera: margarodidae) in san joaquin valley citrus. when adult beetles were exposed to treated citrus leaves, adult survival was significantly reduced by the foliar neonicotinoid imidacloprid and the pyrethroid cyfluthrin. progeny ... | 2003 | 14650510 |
