“…Valério and Nakano [ 12 ] also reported an increase in dry mass content in B. decumbens infested with high densities of adults of Zulia entrerriana . Weaver and Hibbs [ 33 ] and Marthus and Pienkowski [ 34 ] who studied Philaenus spumarius in alfalfa and red clover, respectively, and Fagan [ 35 ], who studied Prosapia bicincta in Digitaria decumbens , also observed increases in the percentage of dry mass content in these host plants as a result of damage caused by spittlebugs. The increase in dry mass found in the above results is a negative effect, since damages imposed by the spittlebug result in early drying of the plants.…”

The aim of this study was to determine the damage in Brachiaria ruziziensis (Germain & Edvard) according to the density of and exposure time to adults of Mahanarva spectabilis (Distant, 1909) (Hemiptera:Cercopidae). Each plant was kept with 0, 12, 18, or 24 adults of M. spectabilis for five or ten days. Then, the insects were removed from the plant, and the following parameters were evaluated: content and loss of chlorophyll, visual damage score, shoot dry mass, and the capability for regrowth. In fact, plants exposed to the highest level of infestation for 10 days showed an 80.97% loss of chlorophyll, which is 25% higher than that shown by the plants exposed for five days. The damage score also increased with infestation levels. In the levels of 12 and 18 adults per plant, the damage score increased with increasing time of exposure. The dry mass content was higher in plants exposed to 24 insects for 10 days, suggesting that the attack of spittlebugs caused premature drying of the plant. These effects caused significant reduction in the number of tillers of infested plants. Our results indicate that exposure to adults of M. spectabilis causes significant damage and affects the development and persistence of B. ruziziensis plants.

“…Those authors attributed the increased dry matter percentage to the reduced fresh weight from insect damage. The increased dry matter percentage was also reported for B. decumbens infested with Zulia entreriana adults [ 11 ] in alfalfa; red clover attacked by Philaenus spumarius [ 32 , 33 ]; and Digitaria decumbens infested with Prosapia bicincta [ 34 ].…”

The aim of this study was to determine the damage caused by adult Mahanarva spectabilis (Distant, 1909) (Hemiptera: Cercopidae) on Brachiaria ruziziensis (Germain & Evard) under field conditions. A total of 0, 4, 8, 12, or 16 M. spectabilis adults per plot were maintained for 6 days. Thereafter, the insects were removed from the plant, and the following parameters were evaluated: chlorophyll content, damage score, dry as well as fresh weights, percentage of shoots' dry matter, and the forage's ability to regrow. The chlorophyll content was significantly reduced; the damage score and percentage of dry matter in plants increased depending on the increased insect infestation density after 6 days of exposure. In contrast, no change was observed on the B. ruziziensis fresh and dry weights as well as the regrowth capacity depending on the M. spectabilis infestation densities. Attacks by 8 adult M. spectabilis per clump of B. ruziziensis with an average of 80 tillers for 6 days were sufficient to reduce the chlorophyll content and the functional plant loss index. This density can be a reference for spittlebug integrated management in Brachiaria.

FAGAN (1969), afirma que nastaqens com qrancle densidade de caules e touceiras, formam uma proboçào contra vcntos quer tes (reduzem a evaporação) e altas temperaturas, aumentando a taxa de sobreviência de ninfas.…”

Effect of the litter removal on the spittlebug (Homoptera: Cercopidae) popuiation, ifl Erc7caría 7ho' pastures This work was carried out in order to evaluate the effect of removal of accumulated litter at the soil levei, on the spittlebug population, on B• rj pastures. The data cor sisted of nyrnphs and adults countinq which were obtained by sampiing the Dastures during 17 months, in plots which hadthe litter manually removed and piots where the litter was mcmtained.It was observed that the litter favoured the spittlebug popuiation as the number of these insecta in plots with removed litter was sianificantiy lower than where It was maintained. The averaqe reductions observcd for nymphs and adults were, respectiveily, 60 and 30%.
