“…4). For instance, many mothssome of them using tomato and tobacco as hosts for their larvae [38,39] can hear and react to ultrasound in the frequencies and intensities that we recorded [22][23][24]. These moths may potentially benefit from avoiding laying 20 their eggs on a plant that had emitted stress sounds.…”

the plant's condition -dry, cut, or intact -based on its emitted sounds. Our results suggest that animals, and possibly even other plants, could use sounds emitted by plants to gain information about the plant's condition. More investigation on plant bioacoustics in general and on sound emission in plants in particular may open new avenues for understanding plants, and their interactions with the environment.15 20

“…Crops such as soybeans and beans have suffered from constant population outbreaks of Chrysodeixis includens (Walker, 1857) (Lepidoptera: Noctuidae) [1] [2], known as soybean looper [3], with great defoliator potential [4] of polyphagous habit [5].…”

The objective was to determine lethal concentrations and to evaluate the effects of sublethal doses of insecticides on Chrysodeixis includens under laboratory conditions. The standard population of C. includens was kept on artificial diet under controlled conditions (25˚C ± 5˚C, 60% ± 10 RU, 12:12 h). The active principles used were B. thuringiensis, Indoxacarb and Teflubenzuron.The CL 25 and LC 50 obtained from dose response curve (estimated from eight concentrations of each active principle) were diluted in water and applied to the back of third instar caterpillars and compared to the control (water). The insecticides used showed lethal and sublethal effects in C. includens. Bacillus thuringiensis was 6.21 and 2.79 times more toxic to soybean looper when compared to the products Indoxacarb and Teflubenzuron, respectively. Insecticides applied to the caterpillars reduced survival and affected the biomass gain with increased larvae and pupae longevity, with a significant reduction in fertility (40%) and fecundity (94.97%) in adults. In the present study it was observed that both survival and larval biomass gain have a direct effect on fecundity and fertility, respectively. Therefore the active ingredients Indoxacarb, Teflubenzuron and B. thuringiensis can be used in rotation as a tool in the C. includens.

“…to its: occurrence in all states of the country; high polyphagia, with 175 species of host plants; and resistance to control measures, such as the application of insecticides, which can be explained by the habit of the species taking shelter in the middle and lower thirds of the plant (Hoffmann-Campo et al, 2012;Baldin et al, 2014;Specht et al, 2015). The incorrect use of insecticides and fungicides on soybean has also been identified as a factor that has contributed to the increase of this insect population, particularly by contributing to a high mortality of biological control agents (Sosa-Gómez et al, 2010).…”

-The objective of this work was to evaluate the natural resistance of soybean cultivars to Chrysodeixis includens. For this, four commercial soybean cultivars recommended for the Southern region of Brazil were used: BR 36, NA 5909 RG, BMX Turbo RR, and Benso 1RR. In the laboratory, larvae were subjected to the antixenosis feeding assay, in which they were free or not to choose among old leaves, new leaves, and pods. Neonate larvae were subjected to two antibiosis tests: in the first one, they were fed with leaves from the middle third of the plants of the four cultivars; and, in the second one, with leaves or pods of the NA 5909 RG cultivar. Chrysodeixis includens larvae prefer leaves over pods and old leaves over new ones. The Benso 1RR cultivar extends the development cycle of C. includens, but only BMX Turbo RR will reduce the population growth of larvae in the next generations.Index terms: integrated pest management, IPM, lepidopteran pests, plant resistance, Plusiinae.
