“…The fractional regression analysis for the influence of maximum and minimum temperature on the population shows significant positive influence on two seasons; whereas, relative humidity have a significant positive effect. Temperature was the most extensively studied of all-climatic factors and it appears to have large effects (Haque et al, 2011). Hanafy et al (2014) who found that temperature had a positive effect on mite population on many vegetable crops such as lady's finger, cucumber, tomato, eggplant, bottle gourd and bean.…”

Studies were conducted to define the level infestations of sweet pea and pea crops to the infestation of the spider mite, Tetranychus urticae Koch, and its predatory mite Amblyseius swirskii (Athias-Henriot) during two successive seasons (2016-2017 and 2016-2017) at El-Ayyat-Giza Governorate. Results appeared that the infestation of two cultivars by T. urticae was begun in the first week of October under greenhouse conditions. Progressively increased till its peaks in the third week of June for (sweet pea) and in the first week of February for (pea) during the two successive seasons. Through two consecutive seasons, sweet pea cultivar was the most highly sensitive than pea, arranged in a descending order as follows:

“…), a margarida (Leucanthemum vulgare Lam.) e o tagetes (Tagetes erecta L.) o ácaro-rajado apresentou as maiores populações durante o verão, período no qual são, em geral, registrados os ótimos de temperatura e umidade relativa do ar relacionados ao curto ciclo de vida destes ácaros (DEMIRÖZER et al, 2011, HAQUE et al, 2011). Segundo JEPPSON et al (1975, os ótimos de temperatura para o rápido desenvolvimento de T. urticae oscilam entre 25 e 27ºC.…”

Neste estudo foi avaliada a abundância e a sazonalidade de Tetranychus urticae Koch, 1836 em três cultivares de Gerbera jamesonii Adlam., em cultivo comercial no sul do Brasil. Para avaliação destes parâmetros foram realizadas amostragens de abril de 2011 a fevereiro de 2012. Os ácaros foram obtidos a partir de flores e folhas retiradas de cada uma das cultivares. No total foram contabilizados 10.640 ácaros e de acordo com os testes, a cultivar "Pink Snow" apresentou maior abundância significativa. A análise estatística não evidenciou diferença entre o número de ácaros presentes nas folhas e flores. Em todas as variedades o maior número de T. urticae foi registrado na primavera

“…Ahmed and Aslam (2000) observed that high temperatures reduced the aphid populations on rose plants. Haque et al (2011) observed the annual occurrence of mites on rose plants and demonstrated that the population peaked during April and August and had a positive correlation with temperature.…”

to investigate the effects of temperature, relative humidity, and rainfall on the incidence of sucking pests (thrips, aphids, and red spider mites) on roses. The results showed that the thrips population started to increase in the first week of January, gradually increasing and reaching its maximum (2.6 ± 0.2 individuals/flower) in the first week of February, and then declining. The aphid population started to increase in the second week of November, reached its peak (8.4 ± 0.6 individuals/shoot) in the last week of December, and then declining. The mite population started increasing in the second week of December, increased continuously until its peak (8.4 ± 0.4 individuals/shoot) in the first week of March, and then declining. The populations of thrips, aphids, and mites persisted until the third week of April, the third week of May, and the first week of April, respectively. Daily mean temperature and rainfall were negatively correlated with the increase in the thrips and aphid populations, while relative humidity was positively correlated with it; however, these correlations were not significant. The mite population had a significant positive correlation with temperature and a non-significant negative correlation with relative humidity and rainfall. Multiple linear regression analysis showed that weather variables together predicted 34%, 53.1%, and 41.7% of thrips, aphid, and mite abundance on rose plants.
