Abstract: Neotropical Entomology 34(4): 527-538 (2005) Modelo de Simulação Para Epidemias de Fitomonas em Coqueiro RESUMO -Este trabalho apresenta um modelo matemático determinístico compartimental do sistema composto pela planta hospedeira -coqueiro, o microorganismo patógeno -Phytomonas staheli McGhee & McGhee, e o inseto vetor -Lincus lobuliger Bred. (Hemiptera: Pentatomidae). Inicialmente um inseto sadio torna-se infectado após alimentar-se de uma planta infectada; conseqüentemente ele pode iniciar uma epidemia, … Show more

“…Transmission in both directions (from P. picta to tomato fruit and from tomato fruit to insect) was documented. The nature of the relationship between tomato and P. serpens is not known with certainty; fruit-dwelling trypanosomatids may not actually be pathogenic although phloem-inhabiting trypanosomatids, also transmitted by bugs, cause serious disease and economic losses (e.g., hartrot of coconut transmitted by Lincus lobuliger Breddin (Sgrillo et al 2005 ).…”

“…A more complex model involving coconut palms (the host plant), the pathogenic microorganism -Phytomonas staheli McGhee & McGhee, and the insect vector -Lincus lobuliger Bred. (Hemiptera: Pentatomidae) has been developed by Sgrillo et al (2005) to simulate the dynamics of the disease caused by the pathogen. The population dynamics of healthy and infected insect vectors were included as a subsystem.…”

“…The fact that high populations of Lincus were found in the upper organs of the affected palms (crown of fruit bunches, inflorescences, upper third leaves) is related to the high concentrations of trypanosomatids existing in the asymptomatic stages of slow wilt. Insects of this same genus have also been associated with the transmission of sudden wilt of oil palm (Desmier de Chenon, 1984;Perthuis et al, 1986;Vickerman & Dollet, 1992;Alvañil, 1993;Dollet et al, 1993) and hartrot of coconut palm (Louise et al, 1986;Dollet et al, 1993;Sgrillo et al, 2005) in other countries of Latin America.…”
