“…An effect of host plant on reproduction has been established for several Tetranychid species (e.g., de Ponti 1977;Ribeiro et al 1988;Hilker and Meiners 2002;Praslička and Huszár 2004). In our findings, reproductive parameters of O. punicae seemed to be associated with flavonoid content of grape cultivars: the higher the flavonoids content, the lower the mites' fecundity (R 2 = 63.5, F = 23.48, P \ 0.001) (Fig.…”

Life cycle, fecundity and longevity of the avocado brown mite, Oligonychus punicae (Hirst), were studied on six grapevine cultivars (Tucupita, Villanueva, Red Globe, Sirah, Sauvignon and Chenin Blanc), under laboratory conditions at 27 +/- 2 degrees C, 80 +/- 10% RH, and L12:D12 photoperiod. Mite-infested leaves were collected from vineyards, placed in paper bags and taken to the laboratory. A laboratory mite culture was established using the grape cultivar Criolla Negra as host plant. To elucidate potential effects on avocado brown mite parameters, we assessed levels of secondary metabolites, such as alkaloids, flavonoids, tannins and polyphenols, of leaves of the six grape cultivars, as well as the thickness of the adaxial cuticle-epidermis. The life cycle of O. punicae differed among cultivars with average values ranging between 8.2 days on Tucupita leaves and 9.1 days on Sirah. Relatively high fecundity was found on Tucupita leaves (2.8 eggs/female/day) during 11.4 oviposition days, while low fecundity values occurred on Sirah and Villanueva leaves, with 0.9 and 1.8 eggs/female/day during 7.9 and 6.7 days, respectively. Average longevity of O. punicae females ranged from 8.1 to 17.5 days on Sirah and Sauvignon leaves, respectively. Intrinsic rate of increase (r (m)) was highest on Sauvignon (0.292) and Tucupita (0.261), and lowest on Sirah (0.146) and Villanueva (0.135). Although significant differences in cuticle-epidermis thickness were detected among the six cultivars, it seemed not to affect mite parameters. Secondary metabolite content also varied between the cultivars. Generally, increasing flavonoid content coincided with decreasing reproductive parameters. The natural plant resistance observed in this study could be useful in the development of an integrated pest management program for mite pests in grape production.

The date palm mite, Oligonychus afrasiaticus (McGregor) (Acari: Tetranychidae), is a serious pest of palm date fruits. Life cycle, fecundity, and longevity of this mite were studied on fruits of four date palms, Phoenix dactylifera L. (Arecales: Arecaceae)(varieties: Deglet Noor, Alig, Kentichi, and Besser), under laboratory conditions at 27 = 1 °C, 60 ± 10% RH. Total development time of immature female was shorter on Deglet Noor fruits than on the other cultivars. O. afrasiaticus on Deglet Noor had the highest total fecundity per female, while low fecundity values occurred on Besser. The comparison of intrinsic rates of natural increase (rm), net reproductive rates (Ro), and the survival rates of immature stage of O. afrasiaticus on the host plants suggests that O. afrasiaticus performs better on Deglet Noor fruits. The mite feeding on Alig showed the lowest intrinsic rate of natural population increase (rm = 0.103 day 1). The estimation of difference in susceptibility of cultivars to O. afrasiaticus is crucial for developing efficient pest control programs. Indeed, less susceptible cultivars can either be left unsprayed or sprayed at low threshold.

“…Developmental time was intermediate on JT×MYD hybrid and NL, being reduced by 9.6 and 13.4%, respectively in relation to JT. Furthermore, effect of coconut cultivar on R. indica Host plant effect on phytophagous mite species reproduction was previously shown as growing, without effect, or decreasing (Ribeiro et al, 1988;Hilker and Meiners, 2002;Praslička and Huszár, 2004). Differences in R. indica developmental time was observed when reared on coconut cultivars, being 21.5 and 19.8 d on JT (in Trinidad) and on a hybrid MYDxJT (in Venezuela), respectively (Vásquez et al, 2015).…”

The increase in oxidative enzyme activities is related to diminished mite infestation. Some biological aspects of Raoiella indica Hirst reared on the coconut cultivars ('Jamaican Tall' (JT), 'Malayan Yellow Dwarf' (MYD), Niu Leka (NL) and a hybrid JT x MYD) were studied under laboratory conditions. Aditionally, changes in oxidative enzyme activities (peroxidase and polyphenol oxidase) as response to R. indica feeding were studied in the cultivars where red palm mites showed highest and lowest biological parameters values. Longer time spans and lower oviposition rates observed on the JT suggest this cultivar to be more resistant to R. indica feeding. Cultivar JT showed the highest value in PPO/POX ratio, being about twice the value shown by MYD in the infested plants. The observed enzyme activity ratios in both genotypes showed a slight increase 24 h after mite infestation, suggesting these enzymes could be related to plant resistance to R. indica. However, this relationship is still unclear. The biological parameters of R. indica together with higher enzyme activity, particularly on JT suggest this cultivar could be considered as a more resistant cultivar as compared to MYD. More detailed studies are required to determine the effect of these enzymes on coconut resistance to red palm mites.
