This work makes a approach of the familiar agriculture of the Assentamento Redonda in the City of Icapuí in the State of the Ceará, objectifying tytisy to identify, to classify the familiar agriculturists having for base the survival strategies put in practical for these actors in the process of local development. The methodology adopted in the work searched to make possible adequate knowledge of the agricultural activity and the agricultural agriculturist, through the analysis of economic performance and parameters that they make possible to measure the stimulus to the investment in the production, as well as the degrees of integration to the market and specialization of the production. In accordance with the gotten results, in the studied locality, the properties are considered integrated to the market and possess greater specialization in the cattle production and of cashew chestnut. Between the studied producers, it has low stimulus to invest in the farming production; this if must to the fact from that the majority of the income of the seated ones is proceeding from other sources as: retirements, pensions, stock market family (bolsa família), wages and others, what it becomes the agricultural activity relatively less attractive. Words Key: Tipificação, Familiar Agriculture, System of Production, Icapuí-ce.

This work objectified to study the nutritional composition of the espinheiro (Machaerium aculeatum Raddi.), in dry and rainy season under pasture of Brachiaria decumbens Stapf in the conditions of Itambé, Pernambuco, Brazil. The experiment was carried out at Experimental Station of Itambé, of the IPA. It was identified 20 trees of the specie in the pasture, in which were realized eight collections of leaves and twigs (diameter<0.5 cm), half at the dry period and half at the rainy period. It were determinate the dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), potassium (K), nitrogen (N), calcium (Ca), magnesium (Mg), and phosphorus (P) contents. The CP, ADF, K, N, Ca and Mg contents were larger (P<0.05) in the rainy season, with average 14.7; 39.7; 1.7; 2.3; 1.1 and 0.5%, respectively. NDF and P contents had not differed between the seasons, with average 49.1 and 0.1%. The espinheiro presents similar chemical composition to the one of other legumes forages. The season of the year exerts influence on the chemical composition of the espinheiro.

The objective of this paper was to know the species of the leafminer (Diptera: Agromyzidae) associated with melon plant Cucumis melo L., in the Chapada do Apodi, semi-arid region of the Rio Grande do Norte state, and report losses due to leafminer mining. This way, leaves infested with leafminer larvae were collected in the field and carried to laboratory, in order to obtain pupae. These pupae were placed inside glass containers until adults emergence. All identified adults belonged to Liriomyza trifolii (Burgess). In some farms leafminer caused losts that range from 10 to 15% of the whole area, due to low fruit ºbrix value. From pupae also emerged some Opius sp. (Hymenoptera: Braconidae) individuals, a leafminer natural enemy, endoparasites the larva-pupae of L. trifolii.

The experiment was carried for 12 months in the Rabbit Unit of Departamento de Zootecnia at the Universidade Federal do Ceará. The aim of this work was to evaluate the rabbit reproductive parameters and ponderable performance of the races New Zealand (NZ) and Califórnia(CA) , in Ceará, Northeast Brazil. Animals were fed with a commercial feed of 2500 kcal DE/kg for rabbit in reproduction. Thirty does (50% of each race) were distributed at random in experimental cages, such that each ¿treatment¿ (race) had 15 replications. Data were analyzed in a complete randomized design. Does were selected by weight and age, being included in the expeiment with 3,0 kg and 4,5 months of age, approximately. The male/female ratio was 1:10. Pregnancy check was done by palpation 15 days after mating. Reproductive management adopted was mating 10 days after delivery and weaning at 30 days of age (semi-intensive). Productivity in maternity was similar between races. Numeric productivity for both races was 31.3 rabbits weaned/cage/year. Does CA showed greatest maternal ability as compared with NZ does, with heavier offspring at birth, at 21 days, and at weaning. Finally, it is suggested that to produce a rabbit for slaughtering, it should use females CA with males NZ, in single or industrial mating.

The in vitro propagation can provide the production of uniform plants, with high quality and free of diseases, and allow fast and genetically reliable multiplication of new cultivars and hybrids. In this context, the present work had the aim at developing a protocol for the in vitro propagation of Ananas lucidus Miller. Two experiments have been carried through, the first on the effect of BAP on nodal multiplication, an the second on plantlet acclimatization. For the multiplication it was used a completely randomized factorial design with 10 repetitions, and 2x5 factors, composed by two consistences, solid and liquid, and five BAP dosages (0,0; 1,0; 2,0; 3,0; 4,0) mg L-1. For the acclimatization experiment it was used a randomized blocks design with 5 treatments, 5 repetitions and 5 plants in each experimental unit, it being tested different substrata (coconut fiber, compost of plant residues, vermiculite, coconut fiber + compost, and vermiculite + compost). The number of sprouts (NB) produced in the liquid medium in the 2,0 mg. L-1 BAP dosage treatment was greaterthan in the 0,0 mg L-1 dosage, at a 5% probability level, and similar to the 1,0; 3,0 e 4,0 mg.L-1 dosages. It was observed that in the liquid media treatments there was a higher proliferation of sprouts than in the semi-solid media (11,3 and 9,0 respectively). The acclimatization survival index was of 96% for all treatments.
