| plant resources and colony growth in an invasive ant: the importance of honeydew-producing hemiptera in carbohydrate transfer across trophic levels. | studies have suggested that plant-based nutritional resources are important in promoting high densities of omnivorous and invasive ants, but there have been no direct tests of the effects of these resources on colony productivity. we conducted an experiment designed to determine the relative importance of plants and honeydew-producing insects feeding on plants to the growth of colonies of the invasive ant solenopsis invicta (buren). we found that colonies of s. invicta grew substantially when th ... | 2008 | 18419921 |
| cytogenetic and taxonomic studies of some legless mealybugs (homoptera, coccinea, pseudococcidae). | a new monotypic genus and species, komodesia circuliplurimagen. et sp. n., from flores is. (indonesia) and the new species, antonina diversiglandulosasp. n., from southern thailand are described and illustrated. chromosomes of these species and also the ones of antonina purpurea signoret, 1872 and antonina thaiensis takahashi, 1942 are studied for the first time: 2n = 30, 20, 12 and 22+bs correspondingly; the male embryos of all four species demonstrate lecanoid paternal heterochromatinization o ... | 2016 | 28123680 |
| distribution and abundance of parasites of the rhodesgrass mealybug, antonina graminis: reassessment of a classic example of biological control in the southeastern united states. | control of the rhodesgrass mealybug, antonina graminis maskell (hemiptera: pseudococcidae), by the encyrtid wasp neodusmetia sangwani is considered a textbook example of classical biological control. however, recent evidence suggests that a. graminis is abundant in the southeastern united states and no recent surveys have been conducted to determine the status of n. sangwani or other a. graminis parasites. a survey was conducted and it was found that n. sangwani was uncommon overall, occurring a ... | 2009 | 20050768 |
