“…Climatic factors considerably influence the aphid pest populations [ 2 ]. Temperature is considered the most important abiotic factor affecting physiology [ 17 ], aphid reproduction rates [ 17 ] and, consequently aphid population dynamics [ 18 ]. However, we have little detailed understanding of stability and change in field populations of fennel aphids, but certain features of applied population dynamics have been revealed.…”

“…The temperature-dependent development of the fennel aphid means that limitations and thermal constants can be established for these insects, with time quantified in degree-days [ 16 ]. Therefore, we can predict the outbreak of an arthropod pest, such as aphids in agricultural systems [ 17 , 18 ]. This information will help us make decisions on how to implement integrated pest control programs [ 19 ], predict population peaks, and establish the timing for sampling operations and ecological zoning [ 20 ].…”

Hyadaphis foeniculi (Passerini) (Hemiptera: Aphididae) is a cosmopolitan species and the main pest of fennel in northeastern Brazil. Understanding the relationship between temperature variations and the population growth rates of H. foeniculi is essential to predict the population dynamics of this aphid in the fennel crop. The aim of this study was to measure the effect of constant temperature on the adult prereproductive period and the life table fertility parameters (infinitesimal increase ratio (rm), gross reproduction rate (GRR), net reproduction rate (R0), finite increase ratio (λ), generation time (GT), the time required for the population to double in the number of individuals (DT), and the reproduction value (RVx)) of the fennel pest H. foeniculi. The values of lx (survival of nymphs at age x) increased as the temperature rose from 15 to 28°C and fell at 30°C, whereas mx (number of nymphs produced by each nymph of age x) increased from 15 to 25°C and fell at 28 and 30°C. The net reproduction rates (R0) of populations of H. foeniculi increased with temperature and ranged from 1.9 at 15°C to 12.23 at 28°C for each generation. The highest population increase occurred with the apterous aphids at 28°C. The rate of population increase per unit time (rm) (day) ranged from 0.0033 (15°C) to 0.1995 (28°C). The highest values of rm were recorded at temperatures of 28°C and 30°C. The rm values were a good fit to the models tested, with R2 > 0.91 and R2 adj > 0.88. The models tested (Davidson, Sharpe and DeMichele modified by Schoolfield et al., Logan et al., Lamb, and Briere et al.) were very good fits for the rm values observed, with R2 > 0.91 and R2 adj > 0.88. The only exception was the Davidson model. Of the parameters studied, the reproductive capacity was higher in the apterous aphids, with the unique exception of daily fecundity at 28°C, which was higher in the alate aphids of H. foeniculi. Parameters relating to the age-specific fertility table for H. foeniculi were heavily influenced by temperature, with the highest biotic potential and population growth capacity found at 34°C. Therefore, the results obtained in this study could be of practical significance for predicting outbreaks of fennel aphids and improving the management of this aphid in fennel crops.

“…With the growing season, the population of these insects increased to the end of harvesting time producing slightly and/or sharply fluctuates to indicate the presence of activity periods. These biofix dates (dates of 1 st appearance) were used to start calculate the degree-day model (Cividanes and Santos-Cividanes, 2012) and consequently predict the occurrence of these insects.…”

“…The occurrence of many insect species had been predicted by Degree day models, such as that of the pink bollworm, Pectinophora gossypiella (Saund.) (Yones, et al, 2012), the date palm scale, Parlatoria blanchardii (Salman, et al, 2016) and aphids (Hanula et al, 2002;Chakravarty and Gautam, 2004;Gomez et al, 2009;Cividanes and Santos-Cividanes, 2012;Tabikha, 2016), helping in the programs of integrated pest management. The current integrated pest management programs for many insect pests are dominated by the use of insecticides that typically rely on sampling, threshold and resistance information to optimize timing of applications and make best use of existing chemistry (Palumbo et al, 2001).…”

Applying a precise forecasting method is necessary to achieve acceptable results in integrated pest management programs. The objectives of this work were to predict the occurrence of population of Myzus persicae (Hemiptera: Aphididae) and Chrysoperla carnea (Neuroptera: Chrysopidae), determine the influence of temperature and relative humidity on their population densities and also to study the effect of five insecticides on the population of these insect species in potato plants under field conditions at Nobaria district, El-Beheira Governorate, Egypt. The populations of M. persicae and C. carnea were monitored on potato plants from February to May of 2015 and 2016 seasons. The population peaks of these insects were predicted using a degree-day model (accumulated thermal units). The obtained results revealed that the green peach aphid has nine field generations while the green lace-wing has two field generations. The general average of deviations between the expected peaks compared to the observed peaks were-1.333 and-1 days in case of M. persicae, while these averages were +3 and-1 days in case of green lace-wing in 2015 and 2016 seasons, respectively. The effect of the meteorological factors such as temperature and relative humidity on population of these insect were studied. The correlation results revealed that the incidence of M. persicae and C. carnea were significantly and positively correlated in descending order with minimum, mean, and maximum temperature degree, respectively. The efficiency of acetamiprid, thiamethoxam, pymetrozine, chlorantraniliprole and pirimicarb on M. persicae and C. carnea populations was determined. These insecticides could be arranged in ascending order as: acetamiprid > thiamethoxam > chlorantraniliprole > pymetrozine > pirimicarb for controlling the green peach aphid. While regarding their harmful effect on the C. carnea population their order became chlorantraniliprole > pirimicarb > thiamethoxam > acetamiprid > pymetrozine. These results were repeated in both seasons of study, 2015 and 2016.

RESUMO:Os insetos estão geralmente associados a uma planta, em sua maioria são considerados pragas, principalmente em cultivos agrícolas, sejam como pragas broqueadoras, sugadoras de seiva, ou até mesmo como vetores de fitopatógenos, sendo neste último uma das causas mais preocupantes, uma vez que muitos fitopatógenos causam doenças que ainda não tem-se um controle eficaz. Sabe-se que no modelo convencional de produção, o manejo das pragas são feitos por controle químico. Este trabalho teve como objetivo fazer uma revisão bibliográfica de trabalhos representativos a respeito do controle de pragas vetores de doenças. A mosca-branca (Bemisia ssp) foi o gênero que mais preocupa os produtores, uma vez que se apresentou como praga em uma grande quantidade de plantas hortícolas, e por ser vetor de vírus, doenças a te então, com controle restrito. Pulgões (Aphididae) também foram relatados, assim como a traça-das-crucíferas (Plutella xylostela) e do tomateiro (Tuta absoluta), controle biológico com o uso de Trichogramma ssp., Beauveria Bassiana, bem como controle físico, químico, etc. De modo geral, vários controles se mostraram viáveis para o controle destas pragas, dentre eles estão o controle químico, físico, genético, biológico e cultural, ambos no intuito de controlar a praga com a finalidade de prevenir a transmissão de doenças por estes. Palavras-chaves:Fitossanidade, Insetos-pragas, Controle de doenças. Abstract:The insects are usually associated with a plant, for the most part are considered pests, particularly in agricultural crops, are as broqueadoras pests, sap suckers, or even how plant pathogens vectors, with the latter one of the most disturbing causes a since many pathogens cause disease that still has to be an effective control. It is known that the conventional model of production, pest management are made by chemical control. This study aimed to do a literature review of representative works about pest control disease vectors. The whitefly (Bemisia spp) was the genre that most worries the producers, as it is presented as a pest in a lot of vegetable plants, and for being virus vector, the diseases you then, with strict control. Aphids (Aphididae) have also been reported, as well as the moth-the-cruciferous (Plutella xylostela) and tomato (Tuta absoluta), biological control using Trichogramma ssp., Beauveria bassiana, as well as physical, chemical control, etc. In general, various controls have proven viable for the control of these pests, among them are the chemical, physical, genetic, biological and cultural control, both in order to control the pest in order to prevent the transmission of diseases by these.
