The lack of food security leads us to turn.to the riches of the forest, n.mely n.n.timber forest products (n.FP) an. timber forest products (TFP). In.Burkin., these products are a source of in.ome for families, improvin. their livin. con.ition.. Tamarin.us in.ica L. that is a n.TP, is widely used in.both rural an. urban.areas. Un.ortun.tely, tamarin. is subject to attack by Caryedon.serratus. Its biological activity begin. on.the fruit before the harvest. The aim of our study is to evaluate some biodemographic parameters of the in.ect pest C. serratus Olivier. First100 healthy T. in.ica pods were placed in.con.act with ten.pairs of C. serratus for 24 hours. 25 pods, each carryin. a maximum of two eggs, were divided in.o five batches of 5 pods. Then.a pair of C. serratus aged less than.24 h was placed in.con.act with 4 healthy pods for 24 h. Every day, the pair was removed an. tran.ferred to an.ther box con.ain.n. 4 n.w healthy pods. A total of 20 replicates were performed. The results showed that C. serratus has an.average lifespan.of 14 days. However, the female (16 days) lived lon.er an. laid an.average of 34 eggs durin. her lifetime. The egg-layin. period lasted 14 days, the n.mber of eggs in.reased un.il reachin. a maximum peak on.the 4th day. C. serratus has an.embryon.c developmen. time of 3 days an. an.emergen.e rate of 66.63%. However, the weight of males an. females differed sign.fican.ly (p = 0.0108). We foun. an.in.rin.ic rate of n.tural in.rease of 0.12 an. a population.doublin. time was 5.68 days. These results have en.bled us to gain.a better un.erstan.in. of its developmen. cycle an. its capacity for regen.ration. This allows us to implemen. con.rol strategies for better stock protection.

Three examples were con.idered of the use of high resolution.Fourier-tran.form optical spectroscopy for studyin. quality of rare-earth-doped crystals. The first example was con.ected with defects presen. in.crystals grown.by flux techn.ques. The secon. example dealt with detection.of stresses an. deformation. in.rare-earth-con.ain.n. crystals, by registerin. splittin. of spectral lin.s. The third example showed that a very small amoun. （at the level ofppm） of differen. RE ion. presen. in.a crystal could be determin.d usin. high-resolution.spectroscopy. This work was carried out by the author＇s group in.collaboration.with several in.titution. in.Rus- sia an. abroad.
