Though their utilization is not a novelty, it has been rather common before inorganic insecticides became available.

Afterward, the material was percolated on a silica gel 60 g column, using hexane, dichloromethane and ethyl acetate successively.

L -1 gibberellic acid GA solution for 2 hours; 4 immersion in a mg. Termite resistance tests of hardwoods of Kochi growth. Rev Bras Plantas medicinais 7: Kining maong panid kataposang giusab niadtong 18 Enero sa Our current knowledge of the viability and storage potential of C.

July 14, ; Revised: Considering the advancement of researches on the botanical insecticides and their potential for pest control and the need to find slow action products to be incorporated into baits for control of subterranean termites, the objective of this study was to evaluate the potential termiticide of the ethanolic extract of bark of C.

Considering the advancement of researches on the botanical insecticides and their potential for pest control, the objective of this work was to evaluate, under laboratory conditions, the bioactivity of methanolic extract, semipurified fractions and crude resin of Croton urucurana Baillon, Euphorbiaceaeagainst Anagasta kuehniella Zeller, Lepidoptera: In terms of stored seeds under both incubation conditions, it was observed that there were significant interactions for all of the characteristics evaluated except for GSI and root size under greenhouse conditions.

A Modern Synthesis, Bignell, D. The highest first count percentages of total germination and the highest germination speed indices were observed uruccurana control froton and in those which were treated with water or mg. 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.


Chemical composition and antimicrobial activity of Croton urucurana Baillon (Euphorbiaceae).

As for the values of LC 95, the ethanol-water fraction ppm also showed higher toxicity compared to other compounds Table 2. The seedlings grown under greenhouse conditions had higher fresh and dry weights due to longer periods of evaluation, which allowed them to accumulate more mass than the seedlings maintained in growth chambers under alternating temperatures. Journal of Stored Products Research 40 The gradual decrease in the germination percentages of seeds stored at room temperatures is clearly visible at the time of the third evaluation, and suggests that deterioration became more pronounced after this time.

Similar to Bixa orellana L. As the intestines of Termitidae family consists of a consortium of bacteria and endogenous cellulolytic enzymes Tokuda et al.

Figure 2 E;F showed that with the diet containing FDM food ingestion and excrements produced were reduced, with lower insect weight gain.

Food ingestion and utilization by the insects was determined according to Parra The low emergence percentages observed under greenhouse conditions on the first count may be explained by the fact that the seeds were exposed to temperature and humidity fluctuations that could reduce the speeds of the metabolic reactions necessary for seedling germination and emergence.

Nutritional Indexes for A. Traps were brought to the laboratory and the termites were transferred to plastic boxes containing moist soil. Ecotoxicology and Environmental Safety 47 Annual Biochemistry 72 In this paper, poisoning symptoms appear rapidly in workers of H.

There are not many works available in the literature on the insecticidal activity of Euphorbiaceae species, which present diverse biological activities. Burkart by Kissmann et al. Sinonimo Oxydectes urucurana Baill.

For the larvae fed with solutions of this fraction in concentrations of 0. Estimate of lethal concentration: The eletrophoresis of the midgut homogenates from the control larvae and the larvae treated with EMeOH and crude resin showed that there were no changes in the pattern of digestion products of the treated larvae compared to the control.

Use of plants with insecticidal properties: Four replications of 25 seeds were used in all tests. Ang Wikimedia Commons may mga payl nga may kalabotan sa: According to the same authors, the inverse correlation between the AD and ECD values was probably because when digestibility was high, there was a proportional higher expenditure of digested food on the metabolic energy, which resulted in a lower biomass gain per unit of digested food, corresponding urucugana ECD.

Termitidae treated with extract obtained from seeds of Croton tiglium L. Jatropha curcas Euphorbiaceaeknown for its insecticidal properties, affects the insects of various families, and its ingestion inhibits the growth of several Lepidoptera species Sauerwein et al.

Thus, these compounds have high probability of being urkcurana in controlling subterranean termites. Journal of Applied Entomology The leaves and bark of Froton. Male flowers Photograph by: March 01, ; Accepted: Lethal concentration analyses showed that the ethanol-water fraction presented the lowest value uucurana LC 50 ppm and LC 95 ppm and it was considered the most toxic fraction for H.

Seeds tend to lose humidity after ripening, which may disrupt the cell membrane and lead to electrolyte leakage from the cells to the external environment. Filter paper treated with crude extract and fractions of C. L -1 gibberellic acid for croron hours. A colorful model for genetics, biochemistry, cell biology and biotechnology. The resulting absorbance was read at nm.
