Chitosan induces tolerance to abiotic stress agents in plants. However, studies on the diferent application forms of this biopolymer are limited. This study evaluated the efect of two forms of chitosan application on the morphophysiology of and metal accumulation by Talinum patens cuttings subjected to Cd to develop new cadmium (Cd) decontamination technologies. Cuttings from 75-day-old plants were transferred to a hydroponic system. For 30 days, three Cd concentrations (0, 7, and 14 mg L-1) and three forms of chitosan application (without application, root, and foliar) were applied. The cuttings were tolerant to Cd because the metal did not infuence biomass production or photosynthetic efciency. Neither chitosan application nor Cd increased the modifed chlorophyll content and fuorescence parameters. However, foliar chitosan reduced the transpiration rate. At the highest concentration of Cd, the application of chitosan in the root reduced the Mg content of the root system and shoots. The root application of chitosan increased the surface area and volume of thicker roots at the expense of fner ones. The foliar application resulted in greater total root length and surface area, mainly those fner. Furthermore, chitosan applied to the leaves activated catalase in the roots and leaves. In contrast to the root application, foliar application increased the accumulation of Cd in the roots. The action of catalase and the increase of fne roots may have favored a greater absorption of the nutrient solution and Cd in the chitosan foliar application treatment. It is concluded that chitosan foliar spraying can improve Cd rhizofltration with T. patens. MenosChitosan induces tolerance to abiotic stress agents in plants.

Fopius arisanus Soman (Hymenoptera: Braconidae) is a generalist tephritid egg parasitoid from the Indo-Pacific region introduced to Brazil in 2012 to control the exotic fruit fly pest Bactrocera carambolae Drew & Hancock (Diptera: Tephritidae) in the northern region. Doryctobracon areolatus Szépligeti (Hymenoptera: Braconidae) is a native generalist parasitoid of second instar larval fruit flies from Central and South America. Because both species of fruit fly parasitoids share some genera of fruit fly hosts, we evaluated if the commercial release of F. arisanus could cause adverse effects (e.g., competitive displacement) on the native parasitoid. Host preference and competitive ability were compared using as hosts the native Anastrepha fraterculus Wiedemann (Diptera: Tephritidae) and the exotic Ceratitis capitata Wiedemann (Diptera: Tephritidae) fruit fly species. To evaluate host preference, choice and no-choice experiments were conducted with lines of F. arisanus reared from each of the hosts. Laboratory studies showed that F. arisanus accepted only 2-3% of the native hosts compared to 34-41% of the exotic hosts under no choice conditions, with similar results when given a choice of native and exotic hosts. The field cage choice study showed similar results when F. arisanus was reared on the exotic host, but when reared on the native host, F. arisanus parasitized more of the native host than when reared on the exotic host. However, both lines of the parasitoid preferred the exotic host. To evaluate competitive ability, experiments with both species together and separate were conducted in the laboratory and in field cages. Both experiments showed that F. arisanus had no measurable detrimental effect on the native parasitoid in either the native or exotic host. Indeed, the native parasitoid was consistently the superior competitor in native host even though it parasitized larvae while F. arisanus is an egg parasitoid. These results indicated that F. arisanus interacted minimally with the native parasitoid on the native host, and while it interacted with the native parasitoid on the exotic host, it did not detrimentally affect it. Thus, F. arisanus is unlikely to cause adverse effects on the native parasitoid, D. areolatus in Brazil.
