“…Aphids on the MNCO4-792F-129 line had longer reproductive period (7.6 days) than those on the VITA 7 standard. Such values were lower than those found by Valente et al (2014), who reported a reproductive period of 4.20 days for cowpea aphid feeding on cultivar TVu 408 (a genotype regarded as aphid-resistant). On the other hand, De La Palva and Sepúlveda-Cano (2015) reported cowpea aphid reproductive periods ranged from 14.20 to 14.70 days on V. unguiculata genotypes.…”

“…Na linhagem MNCO4-792F-129, os insetos apresentaram maior período reprodutivo (7,6 dias), superior ao padrão VITA 7. Esses resultados foram inferiores aos encontrados por Valente et al (2014), quando o pulgão-preto ao se alimentar da cultivar TVu 408, considerado um genótipo resistente, apresentou um período reprodutivo de 4,20 dias. Por outro lado, o período reprodutivo do pulgão-preto variou de 14,20 a 14,70 dias sobre genótipos de V. unguiculata, em pesquisa realizada por De La Palva e Sepúlveda-Cano (2015).…”

“…No Brasil, são relatados poucos trabalhos referentes aos aspectos biológicos do pulgão-preto sobre o feijão-caupi (VALENTE et al, 2014;PORTELA, 2018), utilizando-se geralmente a cultivar VITA 7, pouco cultivada pelos agricultores e altamente suscetível à praga BLEICHER, 2007;SILVA et al, 2018). Por outro lado, muitas cultivares de feijão-caupi já lançadas no mercado apresentam-se como suscetíveis ao pulgão-preto (MORAES;…”

The Brazilian cowpea crop has been increasing in recent years due to the launch of new cultivars. However these are, in some cases, susceptible to cowpea aphid. In view of this, studies of the biology of, one of the main insect pests on advanced cowpea lines, is essential, since they form the next new cultivars to be the released. Accordingly, the objective of the evaluate the main advanced cowpea lines that confer resistance over the biological aspects of Aphis craccivora Koch. Eight advanced cowpea lines were studied, plus cultivar VITA 7 to provide a standard for aphid susceptibility. Number of living individuals, the longevity of insects and number of descendants produced were recorded daily. Highest nymph mortality rates, longest inter-generation intervals and the lowest reproductive duration, occurred when the aphids had lines MNCO4-762F-03 and MNCO4-762F-09 as host plants. Daily fecundity values (3.0 to 8.0 nymphs per day) varied according to lineage. Lowest total fecundity values were recorded when aphids fed on MNCO4-762F-03, MNCO4-762F-09 and MNCO4-792F-123 lines. MNCO4-762F-03 and MNCO4-762F-09 lines negatively impacted A. craccivora biology, and were the least suitable as hosts.

“…Among the phytosanitary problems that can negatively influence cowpea productivity are attacks by Aphis craccivora Koch (Hemiptera: Aphididae), also known as cowpea aphid. This pest species causes great damage to the crop, as it can cause both direct effects (from sap sucking), and indirect ones, as the insect is a vector for several viruses that cause diseases for which there is no treatment (Moraes & Bleicher, 2007;Valente et al, 2014;Huynh et al, 2015).…”

The objective of this work was to determine the preference and the demographic parameters of cowpea aphid (Aphis craccivora) in advanced lines of semiprostrate cowpea (Vigna unguiculata), and to verify both the existance and type of plant resistance to this insect attack. Aphid preference to 20 cowpea genotypes was tested in a randomized complete block design, with six replicates. Lines showing the highest levels of resistance and susceptibility in the preference tests were selected for use in the demographic parameter tests. Based on aphid birth rate and mortality, fertility life tables were constructed. The MNCO4-792F-123 line was classified as resistant. The lowest values for cowpea aphid intrinsic and finite growth rates were obtained for the MNCO4-792F-123, and the highest ones for MNCO4-782F-108 and 'BRS Novaera' genotypes, whose levels exceeded those of 'Vita 7', the standard genotype for susceptibility. The MNCO4-792F-123 line is the least favorable for the development of cowpea aphid, while MNCO4-782F-108 and 'BRS Novaera' are the most susceptible ones.

Spodoptera frugiperda (J.E. Smith) is a major pest of cowpea, (Vigna unguiculata [L] Walp.) (Fabales: Fabaceae), and to date, few tactics are available to control this pest. This study was conducted to evaluate whether cowpea commercial cultivars and landrace varieties express antibiosis to S. frugiperda. The commercial cultivars were developed by the Brazilian Agricultural Research Corporation (Embrapa), and the landrace varieties were obtained from indigenous communities of Mato Grosso do Sul, Brazil. The effects of the cowpea genotypes (commercial cultivars and landrace varieties) were assessed on the development, survival, and reproductive capacity of the insect. Out of six genotypes, the two landraces were the most resistant to the pest. Landrace Juti decreased larval weight and survival, and no larvae reached the pupal phase. Landrace Nioaque adversely affected the larval and pupal weight, the period of development from larva to pupa, adult emergence, and the period of development from larva to adult. The cultivar Fradinho was classified as moderately resistant for reducing the larval and pupal weights, and delaying the period of development from larva to pupa. The cultivar Miranda was susceptible regarding the growth and survival of S. frugiperda, however, females reared on this cultivar laid a lower number of eggs. The resistant genotypes, especially the landrace varieties are promising for future plant breeding programs, with the objective of developing resistant cultivars to S. frugiperda larvae.
