| The tribe Attini (Hymenoptera: Formicidae) comprises 14 genera with approximately 230 described ant species, which are engaged in an obligate mutualism with fungi. The fungus is cultivated inside their colonies, using a variety of organic material as substrate. The fungus is used as food by the ants, and in return, the ants nourish, protect, and disperse their fungal cultivars. Although all species of this tribe cultivate fungi, attine ants are quite heterogeneous in relation to agricultural system, colony size and social structure, substrate preparation behavior, foraging behavior, etc. Agriculture, symbiosis and natural history traits of fungus-farming ants are discussed in this review, as well as future research directions. |

| A traça-da-castanha (Anacampsis phytomiella) é a praga mais importante do período de frutificação do cajueiro porque ataca o fruto (castanha), causando elevados prejuízos por destruir completamente a amêndoa da castanha de caju. O principal sintoma de ataque é a presença de um furo localizado na parte distal da castanha e é conhecido pelo produtor como castanha furada. O adulto é uma pequena mariposa de hábito noturno, com cerca de 1,5 cm de envergadura, coloração escura, com pequenas manchas claras nas asas. O objetivo deste trabalho foi investigar a infestação da traça-da-castanha nos clones de cajueiro-anão CCP 76, BRS 226, BRS 189, cultivados em consorciação com as fruteiras, banana, mamão e melancia, no Campo Experimental da Embrapa Agroindústria... |

| Spodoptera frugiperda (Smith) is a polifagous insect of major economic impact in the western hemisphere and exhibits two strains (i.e., corn and rice) that are morphologically identical but differ in ecology, genetics and physiology. In this work we identified these strains and their respective hybrids by using a PCR-RFLP of the COI gene and PCR of the tandem region FR. Moreover, we performed a population structure analysis by using 253 larvae from Tolima, a region where S. frugiperda is a pest on corn, rice, sorghum and cotton. Corn strain was found on 42% in corn, 34% in cotton, 19% in sorghum and 0.04 % in rice and rice strain on 35% in corn, 0.06% in cotton, 0.06% in sorghum and 53% in rice, demonstrating that corn strain specificity is superior to... |

| Changes in the agroecosystem with the increase of green cane harvesting in Brazil affected the insect populations associated to this crop, and secondary pests like the spittlebug Mahanarva fimbriolata Stål, became much more important. Many studies have demonstrated the active role played by silicon in plant defense against herbivory. The objective of this study was to evaluate the effects of silicon applications on the biology of the spittlebug reared on two resistant (SP79-1011 and SP80-1816) and one susceptible (SP81-3250) sugarcane cultivars. Sugarcane plants were grown under greenhouse conditions and submitted to different treatments: with and without silicon fertilizer in two different soil type (sandy and clay soil). The newly hatched nymphs were... |
