“…The NA with the contents of chlorophyll in the leaves also showed a similar trend. Golawska et al (2010), Calatayud et al (2008), Neves et al (2006) and Stone et al (2001) observed a significant decrease in the values of physiological variables of the plant to increase the plague poblacionalmente, with direct effects on the commercial quality of the flower stalk (Tjosvold and Chaney, 2001). The interruption in the development of floral structure increases with population growth of T. urticae, dispersión en tejido con daño por ácaros, lo que remarca la disminución de la actividad fotosintética en determinados cultivares.…”

The leafminer Liriomyza sativae (Diptera: Agromyzidae) is one of the main pests of melon crop (Cucumis melo) in the Brazilian semiarid. The aims of this study were to determine the damaged leaf area and assess the physiological responses of melon plants submitted to different levels of infestation per larvae of L. sativae. The study was carried out in a greenhouse, using plants of melon of the cultivar Iracema (yellow melon). The design utilized was completely randomized, with five treatments [control (no infestation in the leaves) and four infestation levels (1; 10; 20 and 30 larvae per leaf)] and 10 replications (melon plants). Initially we evaluated the physiological aspects: photosynthetic rate (µmol CO 2 /m 2 /s), stomatal conductance (mol H 2 O/m 2 /s) internal CO 2 concentration (µmol CO 2 / m 2 ) and leaf transpiration (mmol H 2 O/m 2 /s). After the measurements of physiological aspects, the evaluated leaves of each plant were cut close to the petiole and scanned individually with a measuring scale on the side, being the determination of the damaged leaf area performed with the aid of software for processing and analysis of images. The averages of damaged leaf area observed were of 1.2; 6.3; 19.6 and 40.8 cm 2 for infestations of 1; 10; 20 and 30 larvae/ leaf respectively. In relation to the physiological aspects, the rate of photosynthesis, stomatal conductance and transpiration significantly decreased with the increase of leafminer larvae per leaf. The internal CO 2 concentration increased with the increase in the number of larvae per leaf.

BACKGROUND The rice stalk stink bug Tibraca limbativentris (Hemiptera: Pentatomidae) is one of the most important rice pests in Brazil. The search for cultivars that tolerate insect injury is necessary to complement other less aggressive methods of pest suppression. The combination of integrated pest management tactics will reduce insecticide applications and improve the safety of food production. Here, we tested the tolerance response of Xingu, Canela de Ferro and Primavera rice genotypes in glasshouse experiments. In addition, we measured tolerance expressed in a variety of physiological responses, including gas exchange rates, leaf chlorophyll content and reactive oxygen species (ROS) detoxification. RESULTS The results showed that the tolerance of the Primavera genotype to rice stalk stink bug damage was higher, due to (a) a lower reduction of photosynthetic activity, (41% reduction only 96 h after infestation) compared to Xingu and Canela de Ferro (56 and 65% reduction at 24 and 48 h after infestation, respectively); (b) the capacity to maintain the chlorophyll content after infestation, while Xingu and Canela de Ferro reduced their chlorophyll content to 20% and 25% at 72 and 48 h after infestation, respectively; (c) the antioxidative defense system being activated in the first 12 h after infestation, in which superoxide dismutase (SOD) showed an increase of 61% in its activity, and (d) the maintenance of its grain yield, number of panicles per plant, number of filled grains, and spikelets sterility. CONCLUSION Rice genotypes tolerant to herbivory can be identified by measuring the effect of injury and the plant's physiological response by evaluating attributes such as grain yield and its components, gas exchange, chlorophyll content and ROS detoxification. Therefore, the use of rice genotypes tolerant to stalk stink bugs as a component of integrated pest management has the potential to reduce upland rice yield loss.
