“…Of the genotypes that stood out for SCB resistance, hybrid AF-28 is known for possessing multiple insect resistance; in addition to SCB, the hybrid shows resistance to sorghum midge, Stenodiplosis (=Contarinia) sorghicola (Coquillet) (Diptera: Cecidomyiidae), and corn aphid, Rhopalosiphum maidis (Fitch) (Hemiptera: Aphididae). However, hybrid AF-28 exhibits undesirable agronomic characteristics, such as late development and non-erect formation (Rossetto et al, 1976;Boiça Júnior and Lara, 1983;Rossetto and Igue, 1983;Lara and Perussi, 1984;Lara et al, 1997). Therefore, evaluations of different genetic materials should not only take into account the resistance to the pest in question but should also consider other plant parameters, which can result in the identification of genotypes with all desired characteristics for cost-effective grain production.…”

“…In agricultural systems where FAW historically occurs in large populations, there is a need for more frequent monitoring to support decision-making regarding pest control measures such as application of chemical and biological insecticides at adequate times when the economic threshold is reached, although this information for FAW in sorghum is still lacking. Furthermore, given that the market value of sorghum grains has been high in the last years (CONAB, 2020), farmers have been concerned about plant health conditions, investing more time and resources in pest control measures (Rossetto et al, 1976;Boiça Júnior and Lara, 1983;Rossetto and Igue, 1983;Lara and Perussi, 1984;Cortéz and Waquil, 1997;Lara et al, 1997;Carvalho and Dias, 2020).…”

“…The resistant characters seem to be recessive traits (Widstrom et al, 1972;Berquist et al, 1974;Rossetto, 1983); but the number of genes involved is still to be determined.

Rossetto (1983) reported that at least two recessive pairs of major genes are responsible for the resistance of AF-28 to the sorghum midge, but other genes with minor effects might be present.

The agroecosystem is the basic unit of consideration in the integrated pest management approach. The target crop within this ecological system and its level of susceptibility to insect pest species is of fundamental importance, and can be altered genetically through breeding for pest resistance. The relative level of pest resistance as influenced by pest density, demands a knowledge of pest density and plant damage (yield) relationships. An understanding of these relationships leads to the determination of economic injury levels and subsequently to the establishment of dynamic economic threshold levels.Comparing the economic injury level of insect resistant cultivars to that of susceptible cultivars defines the resistance level and provides the base-line data on which to quantify the effects of other direct control tactics and natural pest density suppressing agents.Insect resistant sorghums are used as a model to examine the unique values of this tactic as a component in an integrated pest management strategy; the role they play, and how they influence other direct control and support tactics.Resume-L'agroecosysteme est Punite de base pour une approche de lutte integree. Dans cet ecosysteme, la culture-cle et son niveau de susceptibilite aux especes d'insectes ravageurs sont fondamentals et peuvent etre modifies par l'amelioration genetique de la resistance aux especes nuisibles. Une connaissance des relations densite d'insectes et perte de rendement est necessaire car le niveau de resistance depend de la densite des insectes presents, la comprehension de ces relations permet de determiner les seuils de pertes economiques et done d'etablir une echelle dynamique des seuils d'action. La comparaison des seuils de pertes economiques des varietes resistantes et des varietes susceptibles definit le niveau de resistance et fournit des donnees de base qui permettent de quantifier les effets de tactiques de controle direct ou d'agents naturels suppresseurs d'insectes.Les sorghos resistant aux insectes sont utilises comme modele pour etudier les caracteristiques uniques de cette tactique en tant que composante d'une strategie de lutte integree. Le role de ces sorghos et la maniere dont ils influencent les methodes de controle direct et indirect sont egalement etudiees.

RESUMOo efeito do dano da mosca do sorgo, Contarínia sorqhicole (Coq.) no peso de 100 grãos remanescentes à infestação de panícula infestada foi avaliado em dois híbridos de sorgo (um resistente e um susceptfvel a esta praga).A diferença do peso de 100 grãos provenientes de panículas com diferentes proporções de espiguetas danificadas pela mosca (O éJ' 100%) foi da ordem de 10 e 20% respeétivamente para o híbrido resistente e susceptfvel", Foi observado uma baixa correlação entre o peso de 100 grãos e outros parâmetros como: comprimento, diâmetro e peso da panícula; peso total de grãos e danos da mosca. Entretanto, nos dois híbridos, a distribuição das médias do peso de 100 grãos provenientes de panículas com diferentes proporções de espiguetas danificadas pela mosca aproximou-se de uma função quadrática. O peso máximo de 100 grãos ocorreu quando as panículas estavam com 40 e 50% de espiguetas danificadas pela mosca respectivamente para o hfbrido susceptível e resistente. Isto indica que em panículas sob leves infestações há uma pequena compensação do dano produzindo maiores grãos e sob severa infestação há redução do peso individual dos grãos, que escapam a infestação. Entretanto, esta compensação do dano da mosca não é suficiente para recuperar a perda causada diretamente às espiguetas infestadas.
