A soja, Glycine max (L.) Merril, é uma das culturas de maior importância econômica para o Brasil, considerada uma commodity nacional devido à sua alta produtividade e participação nas exportações no mercado internacional. Dentre os insetos-pragas que causam danos para essa cultura, nos últimos anos agrícolas têm merecido destaque as lagartas de Spodoptera eridania (Cramer), as quais podem se alimentar tanto de folhas quanto das vagens das plantas de soja, causando prejuízos econômicos para os sojicultores, principalmente nas áreas do Cerrado localizadas na região Centro-Oeste do país. O objetivo da presente revisão é disponibilizar informações sobre os aspectos bionômicos de S. eridania, a fim de dar subsídios para futuras pesquisas sobre o manejo dessa praga.Bionomic Aspects of Spodoptera eridania (Cramer): A Pest in Expansion on Soybean Crop in the Region of Brazilian CerradoAbstract. Soybean, Glycine max (L.) Merril, represents one of the major economically important crops to Brazil, and is considered a national commodity because of its high yield and participation in international trade exportations. Among the insect pests that cause damage to this crop, Spodoptera eridania (Cramer) larvae highlighted in the last agricultural seasons by feeding on leaves and pods of soybean plants, and hence causing economical losses to soybean growers, especially in the Cerrado areas located in the Midwest region of the country. We aimed with this review to provide information about bionomical aspects of S. eridania in order to give subsides for further researches on the management of this pest.

Consumption of greenhouse and field grown ‘Bragg’ soybean, Glycine max (L.) Merrill, foliage was determined for Pseudoplusia includens (Walker) larvae treated with varying dosages of Pseudoplusia nuclear polyhedrosis virus to produce different mortality levels. Uninfected P. includens larvae consumed an average of 158.3 and 78.7 cm2 of greenhouse and field grown soybean foliage, respectively. More than 84% of the total leaf area consumed was by the final two larval instars. The amount of foliage consumed by larvae infected as first (greenhouse and field) or second (greenhouse) instars was significantly reduced with increasing NPV mortality level. Foliage consumption by larvae infected as second (field) and third (greenhouse and field) instars at all dosage levels was significantly reduced when compared to the untreated checks, but differences in foliage consumption at the two lower mortality levels were not significant. Frass produced by infected and uninfected larvae was significantly correlated with the amount of greenhouse or field grown foliage consumed.

Mature cowpea (Vigna unguiculata (L.) Walp.) pods with scattered, irregular black spots, similar in appearance to those found on mature soybean (Glycine max (L.) Merr.) pods infected with Phomopsis longicolla T. W. Hobbs, were observed in three fields in Oktibbeha County, MS, in September 1994. In a delayed harvest sample of pods and seeds from one field, a fungus identified as P. longicolla (1) was isolated from more than 60% of surface-disinfested, excised pod disks and from 42% of surface-disinfested seeds. Average frequencies of isolation from seeds harvested at the normal time from the other two fields were 27 and 9%. When surface-disinfested soybean seeds (cv. Avery) were placed along the margins of P. longicolla colonies on potato dextrose agar, the radicals from most germinating seeds became necrotic and many seeds did not germinate. Koch's postulates were completed by reisolating the fungus from diseased tissue. Reference: (1) T. W. Hobbs et al. Mycologia 77:535, 1985.

Chrysodeixis includens and Spodoptera eridania caterpillars have been considered the most important pests for Glycine max in Brazil. This study evaluated different control strategies for these two important soybean caterpillars and the effects on crop productivity. The control strategies adopted were: BC, IPM, PUI and C (without pest control) and 2 cultivars (BMX Desafio - conventional and TEC Power IPRO – transgenic – Cry 1Ac). The experimental design was in randomized blocks in a factorial scheme (2 x 4) with four replications. The transgenic cultivar TEC Power IPRO presents efficiency in the control of Chrysodeixis includens and low efficiency for Spodoptera eridania. Harmonious practices such as IPM are the best alternative for soybean crops, to minimize Chrysodeixis includens and Spodoptera eridania infestations. The control strategy adopted did not influence soybean productivity.

The legume seed coat is the site of sucrose unloading and the metabolism of imported ureides and synthesis of amino acids for the developing embryo. The cell types directly responsible for these functions in the seed coat are not known. We recently described a convex layer of tissue on the inside surface of the soybean (Glycine max L. Merr.) seed coat that was termed “antipit” because it was in direct opposition to the concave pit on the abaxial surface of the cotyledon. Cone cells of the antipit contained numerous hypertrophied Golgi apparatus and laminated rough endoplasmic reticulum common to actively secreting cells. The initial report by Dzikowski (1936) described the morphology of the pit and antipit in G. max and found these structures in only 68 of the 169 seed accessions examined.
