According to these authors, the poisoning symptoms of C. Evolution and Function of Endogenous Termite Cellulases.

Croton urucurana – Wikipedia

In bioassays conducted with H. All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License. As such, seed damage may be evaluated by measuring any increase in the electric conductivity of the imbibed water Vieira Springer, London, New York, urucueana Drawing of the leaves and flowers Photograph by: Toxicology 15 Drops of water were periodically sprinkled onto the sterilized sand in the dishes to maintain sufficient moisture for the termites.

Northeastern Plants, Especially the Ceara.

The leaves and bark of C. Similar results were observed with the “farinha seca” seedlings Kissmann et al. In utucurana context, plant extracts stand out for constituting a rich source of bioactive molecules Elango et al. Instituto Biologico Sao Paulo, The fruits were collected in Februarystored under dry conditions in nylon sacks until their spontaneous opening released their seeds; this process took about 15 days.

Brazilian Archives of Biology and Technology 46, Future studies are needed to confirm the efficiency of the compounds the C. Nich seedlings decreased with seed storage time.

Euphorbiaceae decreased number of colonies of bacteria in the intestinal flora of termites in comparison with those from untreated termites. The first count germination was carried out together with the germination test, which consisted of the percentage record of the normal seedlings, fourteen days after the sowing. Sapindaceae against Aedes aegypti Diptera, Culicidae. The seeds were kept immersed at room temperature for 1, 4, 6 and 8 hours adapted from Loeffler et al.

According to Guerrathe species of Croton have high power insecticide and in some cases are more toxic to insects than the pyrethrum found in chrysanthemum flowers, that offers wide spectrum of action. Croton urucurana seedlings demonstrated greater vigor when the seeds had been stored for days in a cold chamber.

Manejo Integrado de Plagas 42 The germination percentages at the first count 14 days after sowing and final count and their germination speed indices GSI were evaluated according to Popinigis ; the percentage data were arcsine converted. The eletrophoresis confirmed the data obtained from the crooton triptic activity, in which the larvae treated with EMeOH Fig. After drying, the materials were shredded and submitted to extraction with 5 Ctoton of ethanol 3xby means of Buchner funnel with filter paper.

Calendula officinallis Silveira et al. The adult physiology is harmed when the larva is exposed to the limonoids present in this meliaceae.


Dehydrocrotonin and its derivative, dimethylamide-crotonin induce apoptosis with lipid peroxidation and activation of caspases-2, -6 and -9 in human leukemic cells HL Moreover, toxicological studies performed in the rabbits, mice and guinea pigs have proved to be atoxic, according to the rules for plant products.

The results showed no significant differences for the amount of food ingested and excrements produced, comparing larvae fed with control diet to those fed EMeOH Fig. Croton urucurana and its fractions showed potential termiticide, resulting in a high mortality of H. Higher percentages of total germination and GSI were noted during the first count when the seeds were treated by immersion in water and in GA for 12 hours, as well as among those not exposed to any treatment control.

The experiments were performed in the laboratory with foraging workers of this termite using no-choice bioassay method. It is probable that the natural nocturnal-diurnal thermal variations to which the germinating seeds were exposed under greenhouse conditions after and days of storage were lower than the natural thermal variations they experienced after and days of storage and also lower than the controlled thermal variations in the germination chamber.
