A study was carried out at Embrapa Semi-Árido, Petrolina-PE, Brazil, aiming to understand the gas exchange process of the umbu tree (Spondias tuberosa Arr. Cam) in the dry and rainy seasons. Stomatal conductance, transpiration, photosynthesis and internal CO2 concentration were obtained with a portable infrared gas analyzer (IRGA). During the dry season the umbu tree showed a much lower stomatal conductance early in the morning, as soon as the vapor pressure deficit increased, apparently affecting CO2 assimilation more than transpiration. The highest values were detected around 6: 00 am but decreased to the lowest points between 10:00 am and 2:00 pm. During the raing season, however, stomatal conductance, transpiration and photosynhesis were significantly higher, reaching the highest values between 8:00 and 10:00 am and the lowest around 2:00 pm. It was also observed at 4:00 pm, mainly during the rainy season, an increase on these variables indicating that the umbu tree exhibits a two-picked daily course of gas exchange. |

ABSTRACT - This study aimed at assessing selectivity of insecticides to adults of Doru lineare. The tests were performed under controlled environmental conditions. Insecticides tested (g a.i. ha-1) were: flubendiamide (72); chlorantraniliprole (30); chlorantraniliprole (15) + lambda-cyhalothrin (7.5); lambda-cyhalothrin (7.5); chlorpyriphos (480); and control (distilled water). Treatments were sprayed over arenas made up with glass plates (area 169 cm2), imprisoning the insect with PVC rings. The top of the rings was protected with a fine fabric (tulle) where adult insects were sprayed with insecticides using a Potter Tower. Insect survival was assessed at 24, 48, 72, 96, and 120 h after exposing adults to the treatments. Flubendiamide and chlorantraniliprole were classified as harmless (class 1) to D. lineare and therefore apropriated to be used in Integrated Pest Management (IPM) programs since they can be sprayed preserving natural biological control. Chlorpyriphos, lambda-cyhalothrin and the mixture of chlorantraniliprole + lambda-cyhalothrin were harmful (class 4), moderately harmful (class 3), and slightly harmful (class 2), respectively. Non-selective products should also be tested in semi-field and field conditions to evaluate its persistence. Whenever possible, noxious and persistent insecticides should be replaced for more selective ones. RESUMO - Este trabalho avaliou a seletividade de inseticidas a adultos de Doru lineare. Os testes foram conduzidos em condições controladas. Os inseticidas testados (g i.a. ha-1) foram: flubendiamida (72); clorantraniliprole (30); clorantraniliprole (15) + lambda-cialotrina (7,5); lambda-cialotrina (7,5); clorpirifós (480); e controle (água destilada). Os tratamentos foram aplicados em arenas compostas de placas de vidro (área 169 cm2 ), aprisionando o inseto com anéis de PVC. A extremidade superior do anel foi protegida com tecido fino (tule), onde os adultos receberam aplicação tópica dos inseticidas através de Torre de Potter. A sobrevivência dos insetos foi avaliada 24, 48, 72, 96 e 120 horas após a exposição dos adultos aos tratamentos. Flubendiamida e clorantraniliprole foram classificados como inócuo (classe 1) a D. lineare e, portanto, são apropriados para uso em programas de Manejo Integrado de Pragas (MIP) porque podem ser aplicados preservando o controle biológico natural. Clorpirifós, lambda-cialotrina e clorantraniprole + lambdacialotrina foram nocivo (classe 4), moderadamente nocivo (classe 3) e levemente nociva (classe 2), respectivamente. Produtos não seletivos precisam ser também testados em semi-campo e campo para avaliar a persistência. Inseticidas nocivos e persistentes devem, sempre que possível, ser substituídos por outros mais seletivos.
