(Coleoptera: Curculionidae), and flooding on leaf gas exchange (net CO2 assimilation (A), transpiration (E), and stomatal conductance (g,)), plant growth (root, stem, leaf, and total plant dry weights, stem diameter, and plant height) and adult host plant preference (feeding damage and oviposition) were determined on mahogany, Swietenia mahagoni Jacq., and pond apple, Annona glabra L., trees in outdoor screen cages. Flooding reduced leaf gas exchange, plant growth, and D. abbreviatus feeding damage of mahogany trees. Leaf gas exchange of infested and non-infested trees of both mahogany and pond apple were similar except for one measurement date for mahogany. Leaf dry weights were greater for non-infested than infested mahogany trees. There was no effect of infestation on dry weights of pond apple trees. Based on feeding injury to leaves, adults preferred non-flooded to flooded mahogany trees. The lack of response in leaf damage or oviposition to flooding for pond apple was attributable to the avoidance of leaves by adult D. abbreviatus of this plant species despite it being a host for root weevil larvae. The results indicate that while flooding of the root zone adversely affects growth and physiology of mahogany trees, it does not predispose trees to greater damage from adult D. abbreviatus. In fact, adult insect damage was greater for non-flooded than flooded trees. Pond apple was not greatly affected by root zone flooding and was not a preferred host of adult D. abbreviatus under flooded or non-flooded conditions.10aDiaprepes abbreviatus1 aMartin, Cliff, G.1 aMannion, Catharine1 aSchaffer, Bruce  uhttps://weevil.myspecies.info/leaf-gas-exchange-and-damage-mahogany-and-pond-apple-trees-adult-diaprepes-abbreviatus-coleoptera-cu02330nas a2200181   4500008004100000020001400041245016600055210006900221260000800290300001200298490000700310520160600317653002601923100002201949700002301971700002001994856013402014       2011                        eng d  a0015-404000aLEAF GAS EXCHANGE AND GROWTH RESPONSES OF GREEN BUTTONWOOD AND SWINGLE CITRUMELO TO DIAPREPES ABBREVIATUS (COLEOPTERA: CURCULIONIDAE) LARVAL FEEDING AND FLOODING0 aLEAF GAS EXCHANGE AND GROWTH RESPONSES OF GREEN BUTTONWOOD AND S  cJun  a279-2890 v943 aEffects of flooding and herbivory by Diaprepes abbreviatus L. (Coleoptera: Curculionidae) larvae on leaf gas exchange (net CO2 assimilation (A), transpiration (E), and stomatal conductance (gs)) and growth of green buttonwood (Conocarpus erectus L.) and Swingle citrumelo (Poncirus trifoliata (L.) Raf. x Citrus paradisi Macf.) trees were tested. Growth and survival of the larvae were also examined. For each plant species, there were 2 larval infestation treatments (infested and non-infested) and 2 flooding treatments (flooded and non-flooded). Beginning 6 d after larval infestation, plants were flooded in three 1-wk cycles each with 2 d of flooding followed by 5 d of non-flooding. For green buttonwood, E was higher for non-flooded than flooded plants on the third of 5 measurement dates and A and gs were higher for non-flooded than flooded plants on the fifth (final) measurement date. For Swingle citrumelo, E and gs were higher for non-infested than infested plants on the fifth (final) measurement date. Root dry weight of Swingle citrumelo was higher for flooded, infested than for non-flooded, infested plants and for non-flooded, non-infested than for non-flooded, infested plants. Larval survival rate, head capsule width, and root damage rating of Swingle citrumelo were lower for flooded than for non-flooded plants, whereas flooding did not affect larval survival or growth on green buttonwood. Thus, short-term cyclical flooding of three 2-d cycles may control D. abbreviatus larvae on Swingle citrumelo but did not control larval populations or reduce damage on green buttonwood.10aDiaprepes abbreviatus1 aMartin, Cliff, G.1 aMannion, Catharine1 aSchaffer, Bruce  uhttps://weevil.myspecies.info/leaf-gas-exchange-and-growth-responses-green-buttonwood-and-swingle-citrumelo-diaprepes-abbreviatus01845nas a2200181   4500008004100000020001400041245013900055210006900194260000800263300001200271490000700283520114300290653002601433100002201459700002701481700002001508856013501528       2010                        eng d  a0015-404000aSURVIVAL OF DIAPREPES ABBREVIATUS (COLEOPTERA: CURCULIONIDAE) LARVAE ON GREEN BUTTONWOOD TREES IN FLOODED MARL SOIL AND POTTING MEDIUM0 aSURVIVAL OF DIAPREPES ABBREVIATUS COLEOPTERA CURCULIONIDAE LARVA  cJun  a153-1600 v933 aSurvival of Diaprepes root weevil Diaprepes abbreviates (L.) (Coleoptera: Curculionidae) larvae was assessed in flooded marl soil and a flooded nursery potting medium with green buttonwood (Conocarpus erectus L., Combretaceae) as a food source for the larvae. Root-zone flooding may be a viable control option for flood-tolerant ornamental plants including buttonwood. Significantly more larvae survived after 38 d in non-flooded than in flooded marl soil. Similarly, more larvae survived in non-flooded than in flooded potting medium; no larvae were recovered from flooded potting medium. Larval survival rates were significantly higher in flooded marl soil than in flooded potting medium, but there was no difference in survival between non-flooded marl soil and non-flooded potting medium. Larvae recovered from flooded marl soil had significantly smaller head capsule widths and probably were at least 1 instar younger than larvae recovered from non-flooded marl soil or non-flooded potting medium. In summary, flooding marl soil or potting medium reduced survival, and in marl soil flooding slows the growth of D. abbreviatus larvae.10aDiaprepes abbreviatus1 aMartin, Cliff, G.1 aMannion, Catharine, M.1 aSchaffer, Bruce  uhttps://weevil.myspecies.info/survival-diaprepes-abbreviatus-coleoptera-curculionidae-larvae-green-buttonwood-trees-flooded-marl-s
