Attractiveness of host plant volatile extracts to the asian citrus psyllid, Diaphorina citri, is reduced by terpenoids from the non-host cashew. Repositório Alice
FANCELLI, M.; BORGES, M.; LAUMANN, R. A.; PICKETT, J. A.; BIRKETT, M. A.; BLASSIOLI-MORAES, M. C..
Diaphorina citri is a vector of the bacterial causative agent of Huanglongbing (HLB?=?Citrus greening), a severe disease affecting citrus crops. As there is no known control for HLB, manipulating insect behaviour through deployment of semiochemicals offers a promising opportunity for protecting citrus crops. The behavioural responses of D. citri to plant volatiles, and the identity of these plant volatiles were investigated. Volatiles were collected from host plants Murraya paniculata, Citrus sinensis, C. reshni, C. limettioides, Poncirus trifoliata, and from non-host plants Psidium guajava, Mangifera indica, Anacardium occidentale. In behavioural assays, female D. citri spent more time in the arms containing volatiles from either M. paniculata or C....

Changes in concentration of isoflavonoids after cis-jasmone spraying in the leaves of two soybean cultivars. Repositório Alice
GRAÇA, J. P. da; UEDA, T.; JANEGITZ, T.; SILVA, D. M. da; MAEDA, J. M.; MORAES, M. C. B.; BIRKETT, M. A.; PICKETT, J. A.; BUENO, A. de F.; HOFFMANN-CAMPO, C. B..
cis-jasmone is a naturally-occurring compound in plants that activates direct and indirect defence in model and crop plants'". Exogenous application of cis-jasmone increases flavonoid concentrations in soybean and affects negatively Anticarsia gemmatalis weight gain. Here, foliar isoflavonoid concentrations were evaluated after cis-jasmone spraying on soybean cultivars BRS l34 and lAC 100, grown at Embrapa Soybean greenhouse facilities. At V) development stage, plants were sprayed with water, Tween 20 + water or cis-jasmone + tween 20 + water. For flavonoid extraction, leaves were collected 12, 24, 48, 96, and 120h after spraying, and immediately frozen in liquid nitrogen, ground in a mortar and extracted in MeOH 90% or EtOH 80% + HCI (0.001 M)....

Neotropical maize genotypes with different levels of benzoxazinoids affect fall armyworm development. Repositório Alice
MICHEREFF, M. F. F.; NASCIMENTO, I. N.; SANTANA, G. T.; SARRIA, A. L. F.; BORGES, M.; LAUMANN, R. A.; WITHALL, D. M.; CAULFIELD, J. C.; BIRKETT, M. A.; MORAES, M. C. B..
Plants are equipped with various defensive attributes against herbivores, including volatile and nonvolatile compounds. In maize plants, benzoxazinoids mediate resistance against some herbivores, with the most abundant being (2R)-2-β-D-glucopyranosyloxy-4-hydroxy-7-methoxy-2H-1,4-benzoxazin3(4H)-one (DIMBOA-Glc), and its corresponding aglucone 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one (DIMBOA). Both compounds have been shown to interfere in the larval development of generalist herbivores but are less effective on specialist, that is, grass-feeding, herbivores. Using a Brazilian population of Spodoptera frugiperda, we investigated (i) the level of constitutive benzoxazinoids in Neotropical maize genotypes, that is, Zapalote Chico, Mirt...

Persistence and efficacy of a new formulation based on dog allomonal repellents against Rhipicephalus sanguineus sensu lato tick. Repositório Alice
OLIVEIRA FILHO, J. G. de; FERREIRA, L. L.; SILVA, F. de O.; MENEZES, C. M. F.; MUNIZ, E. R.; PAULA, L. G. F. de; SARRIA, A. L. F.; PICKETT, J. A.; BIRKETT, M. A.; MASCARIN, G. M.; BORGES, L. M. F..
Abstract: Beagles are less susceptible to Rhipicephalus sanguineus sensu lato tick due to the production of the allomones benzaldehyde and 2-hexanone. Our previous published work showed that these compounds can reduce tick burden on susceptible dogs. Here we tested the hypothesis that an increase in repellent dose and release rate could increase repellent efficacy and persistence. Slow-release formulations of these compounds, with higher doses and release rates, were tested on artificially-infested dogs. Ten dogs were randomly assigned to two groups with five dogs each. The treated group received collars with slow-release formulations of the compounds attached, while the control group received collars with clean formulations attached. Five environmental...

Semiochemicals from herbivory induced cotton plants enhance the foraging behavior of the cotton boll weevil, Anthonomus grandis. Repositório Alice
MAGALHÃES, D. M.; BORGES, M.; LAUMANN, R. A.; SUJII, E. R.; MAYON, P.; CAULFIELD, J. C; MIDEGA, C. A. O.; KHAN, Z. R.; PICKETT, P. J. A.; BIRKETT, M. A.; MORAES, M. C. B..
The boll weevil, Anthonomus grandis, has been monitored through deployment of traps baited with aggregation pheromone components. However, field studies have shown that the number of insects caught in these traps is significantly reduced during cotton squaring, suggesting that volatiles produced by plants at this phenological stage may be involved in attraction. Here, we evaluated the chemical profile of volatile organic compounds (VOCs) emitted by undamaged or damaged cotton plants at different phenological stages, under different infestation conditions, and determined the attractiveness of these VOCs to adults of A. grandis. In addition, we investigated whether or not VOCs released by cotton plants enhanced the attractiveness of the aggregation pheromone...

The natural plant stress elicitor cis-jasmone causes cultivar-dependent reduction in growth of the stink bug, Euschistus heros and associated changes in flavonoid concentrations in soybean, Glycine max. Repositório Alice
GRAÇA, J. P da; UEDA, T. E.; JANEGITZ, T.; VIEIRA, S. S.; SALVADOR, M. C.; OLIVEIRA, M. C. N. de; ZINGARETTI, S. M.; POWERSH, S. J.; PICKETT, J. A.; BIRKETT, M. A.; HOFFMANN-CAMPO, C. B..
To test the hypothesis that the plant stress related elicitor cis-jasmone (cJ) provides protection in soybean pods against the seed-sucking stink bug pest, Euschistus heros, the growth of E. heros on cJ-treated pods was investigated using three soybean cultivars differing in insect susceptibility, i.e. BRS 134 (susceptible), IAC 100 (resistant) and Dowling (resistant). E. heros showed reduced weight gain when fed cJ-treated Dowling, whereas no effect on weight gain was observed when fed other treated cultivars. Using analysis of variance, a three factor (cultivar x treatment x time) interaction was observed with concentrations of the flavonoid glycosides daidzin and genistin, and their corresponding aglycones, daidzein and genistein. There were increases...

Variability in herbivore-induced defence signalling across different maize genotypes impacts significantly on natural enemy foraging behaviour. Repositório Alice
MICHEREFF, M. M.; MAGALHÃES, D. M.; HASSEMER, M. J.; LAUMANN, R. A.; ZHOU, J.-J.; RIBEIRO, P. E. de A.; VIANA, P. A.; GUIMARAES, P. E. de O.; SCHIMMELPFENG, P. H. C.; BORGES, M.; PICKETT, J. A.; BIRKETT, M. A.; MORAES, M. C. B..
'Smart' plants that release volatile defence compounds in response to pest damage, and which recruit beneficial natural enemies, offer an opportunity for exploiting biological control in future crop protection strategies. Using six maize genotypes, Zapalote Chico (?landrace?), Mirt2A, Sintético Spodoptera (SS), L3, and two commercial hybrids BRS 4103 and BRS 1040, the aim of this work was to evaluate maize responses to larval damage from the fall armyworm Spodoptera frugiperda, a major maize pest in Brazil, and the ability of the egg parasitoid Telenomus remus to respond to HIPVs induced by S. frugiperda damage. Y-tube olfactometer bioassays with T. remus showed preferential responses to the S. frugiperda-induced volatiles of SS and BRS 4103 compared to...
