“…Among the negative effects of rain is the death of small arthropods such as mites by knocking them to the ground or drowning (Leite et al , 2006). The rain may also decrease the mobility of arthropods reducing encounters between sex partners for mating (Bacca et al , 2006) and provide conditions for development of entomopathogenic fungi that are important natural enemies of mites (Van der Geest et al , 2000).…”

“…Because P. latus presents large thermal limits of development (14-32°C) (Ferreira et al, 2006), the temperature variation in the study sites (23-28°C) should not have been enough to affect the populations size of this mite. Among the negative effects of rain is the death of small arthropods such as mites by knocking them to the ground or drowning (Leite et al, 2006).

Spatial distribution studies in pest management identify the locations where pest attacks on crops are most severe, enabling us to understand and predict the movement of such pests. Studies on the spatial distribution of two mite species, however, are rather scarce. The mites Polyphagotarsonemus latus and Tetranychus bastosi are the major pests affecting physic nut plantations (Jatropha curcas). Therefore, the objective of this study was to measure the spatial distributions of P. latus and T. bastosi in the physic nut plantations. Mite densities were monitored over 2 years in two different plantations. Sample locations were georeferenced. The experimental data were analyzed using geostatistical analyses. The total mite density was found to be higher when only one species was present (T. bastosi). When both the mite species were found in the same plantation, their peak densities occurred at different times. These mites, however, exhibited uniform spatial distribution when found at extreme densities (low or high). However, the mites showed an aggregated distribution in intermediate densities. Mite spatial distribution models were isotropic. Mite colonization commenced at the periphery of the areas under study, whereas the high-density patches extended until they reached 30 m in diameter. This has not been reported for J. curcas plants before.

“…The control of F. schultzei is accomplished, traditionally, with chemical insecticides (Cox et al 2006), but the use of these products above recommended rates reduces the beneficial fauna, which in turn increases problems with pests (Atakan 2006;Gusmão et al 2006;Leite et al 2006).…”

Calcium silicate and organic mineral fertilizer increase the resistance of tomato plants to Frankliniella schultzei

et al. 2009

Frankliniella schultzei Trybon (Thysanoptera: Thripidae) is an important pest of tomato plants. The need for more healthful foods is stimulating the development of techniques to increase plant resistance to phytophagous insects. The objective of this research was to evaluate the effect of calcium silicate and an organic mineral fertilizer, alone or in combination, on the resistance of tomato plants to F. schultzei. The treatments consisted of: control (T1), calcium silicate (T2), organic mineral fertilizer (T3), and calcium silicate with organic mineral fertilizer (T4). The mortality of nymphs of this thrips and the number of lesions on tomato leaves were evaluated after three, six, nine and 12 applications of these products. The number of F. schultzei individuals and of lesions on tomato leaves was lower in treatments T2 and T4 than in T1 and T3, showing a possible increase in tomato resistance to this pest. The increase in the number of applications of calcium silicate and the organic mineral fertilizer increased the mortality of nymphs and reduced the damage by this insect on tomato leaves, mainly after nine applications.

“…Acaricides are the main control strategy employed to deal with these pests in vegetable crops (Kousik et al, 2007); however, they may prove to be disadvantageous over the long-term (Razmjou et al, 2009) due to pest resistance (Maniania et al, 2008), interfering in the biological control (Moscardini et al, 2014;Castro et al, 2013Castro et al, , 2015 and increasing pest-related problems (Atakan, 2006;Leite et al, 2006). Therefore, intensive acaricide use should be minimized in pest control (Leite et al, 2003).…”

Preference of red mite Tetranychus ludeni Zacher (Acari: Tetranychidae) to sweet potato genotypes

et al. 2019

Tetranychus ludeni damages the sweet potato. Pest development can vary between plant genotypes. The objective was to identify the preference of Tetranychus ludeni for Ipomoea batatas genotypes, from the germplasm bank at the Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM). Natural infestations of this mite were observed on 54 sweet potato genotypes in potted, in a greenhouse. Three mite-infested leafs of each genotype were collected and analyzed. The red mite showed different population density rate in genotypes. The BD 29 genotype was found to be highly susceptible, the BD 08, BD 57, BD 17 and Espanhola genotypes were moderately susceptible, and the others forty-nine genotypes showed low susceptibility to the mite.
