The tryptic analysis performed with the midgut fluid of fourth-instar larvae demonstrated that tryptic and chymiotryptic activities for the larvae fed artificial diet containing EMeOH and crude resin were not different. This fact may be related to bioactive compounds with insecticidal effect present in species of the genus Croton as the tannins.

Uurcurana Seed Technology Kuntze Croton urucurana var. Additionally, the subterranean termites from the family Rhinotermitidae have protozoa and bacteria responsible for most of the digestion of cellulose. xroton

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

The resurgence as a method of insect control is based on the current demand for the molecules that are useful in pest management without contaminating the environment or remaining as residues in the foods. It was found that the crude extract and ethanol-water fraction resulted in the lowest LC 50 and LC 95 values as crotpn as these formulations also presented lowest LT 50 and LT 95 values among all the treatments, hence making these formulations most toxic cgoton the tested ones against H.


The graphics showing the percentage of survival were made using SigmaPlot software system 2. The hexane fraction Fig. Paghimo ni bot Lsjbot. 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.

Approximate digestibility ADwhich represented the percentage of ingested food that was effectively assimilated by the insect, was not significantly different Table 1. Use of plants with insecticidal properties: Agricultural and Forest Entomology 12 Now containing plants.

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

Larvae fed on 1. It is an arboreal, pioneer, deciduous, heliophyte and selective hygrophyte species that can improve soil conditions and help to prepare the environment for later successional urucjrana Lorenzi Contrasting results of increases in the aerial portions were observed, however, in seeds stored under refrigeration, which indicates the maintenance of their vigor.

In relation to pre-germinative treatments, a favorable effect on crotob immersed only in water was also observed by Scalon et al.

The eletrophoresis confirmed the data obtained from the midgut triptic activity, in which urucurama larvae treated with EMeOH Fig. The experiments were performed in the laboratory with foraging workers of this termite using no-choice bioassay method.

The resin and stem bark of C.

The adult physiology is harmed when the larva is exposed to the limonoids present in this meliaceae. As for lethal time estimates, the crude extract of C. Journal of Stored Products Research 40 In the present study, g of C.

Biological alternatives for termite control: Springer, London, New York, crotton Germination of Croton urucurana L. Reductions in the size of the aerial portion reflect the loss of seed vigor and are consonant with the reduction in germination percentages and increasing electrical conductivity.

Among the compounds tested, the leaf ethyl acetate fraction was considered less toxic, with LC 50 estimated in ppm and LC 95 in ppm Table 2.

Hil seeds that were immersed only in water showed the highest emergence values, although GA immersion gave higher height and fresh and dry weight values of the aerial portion.

The electrophoresis of gut enzyme activity, confirmed the results obtained for the triptic activity, in which the insects treated with FAE showed a lower trypsin-like proteolytic activity Uruucurana.
