“…Further, De Lima et al [27] documented that the total fecundity and daily oviposition rate of T. bastosi Tuttle, Baker & Sales were higher in C. papaya (50.6 ± 4.4), than on P. vulgaris (36.1 ± 2.5) and Manihot esculenta (Euphorbiaceae) (26.5 ± 2.2). Chacón-Hernández et al [11] reported that T. merganser oviposited more on fabaceous plants than on solonaceous plants. Islam et al [28] found that the fecundity of T. truncatus Ehara was greater on malvaceous plants (Corchorus capsularis L. (Malvaceae) (129.6 ± 3.95)) followed by fabaceous plants (Lablab purpureus L. (86.5 ± 3.08)) and caricaceous plants (C. papaya, 84.2 ± 3.59).…”

“…We used the Chacón-Hernández et al [11] formula to measure the percentage of mortality of T. merganser. We measured mortality by the average percent of dead individuals (drowned) outside the leaf square (Σd i /n) × 100, where d i is the number of drowned individuals and n the number of individuals on the leaf square [11]. We recorded the number of dead and alive mites at 24, 48, 72 and 96 h.…”

“…They documented that T. merganser has better performance at 30 • C. Furthermore, Reyes-Pérez [10] found that optimal development for spider mites was at 27 • C on Carica papaya L. (Caricaceae), when evaluated between 19 and 35 • C and 60 ± 2% relative humidity. Chacón-Hernández et al [11] reported that the performance of spider mites was better on beans when compared to wild chili peppers, Capsicum annuum L. var. glabriusculum (Solanaceae).…”

“…The use of botanical extracts [13] and predatory mites, mainly from the family Phytoseiidae [4], are more effective and sustainable strategies to the management of red spider mites, with the added benefit of causing minimal impact on the environment. In Mexico, Chacón-Hernández et al [11] observed that wild chili pepper (C. annuum var. glabriusculum (Dunal) Heiser & Pickersgill) was resistant to T. merganser.…”

Red spider mites, Tetranychus merganser Boudreaux (Acari: Tetranychidae), is an agricultural pest that causes economic losses in papaya and nopal crops in Mexico. The aim of this research was to assess antibiosis and antixenosis as resistance mechanisms in seven host plants (Thevetia ahouai, Carica papaya, Phaseolus vulgaris, Moringa oleifera, Pittosporum tobira, Helietta parvifolia, Capsicum annuum var. glabriusculum) to red spider mites. Antixenosis was evaluated by non-preference for oviposition and feeding, antibiosis by infinitesimal rate of increase, finite rate of increase and doubling time, and the percentage of spider mites mortality. Oviposition and damage by feeding of T. merganser were significantly greater on C. papaya than on the other host plants. The growth rate of the spider mite was significantly lower in P. tobira and T. ahouai than in the other host plants. The percentage of hatched eggs of T. merganser was significantly higher in P. vulgaris than in the other plant species. Based on the demographic parameters, survival, food intake, and oviposition, these results indicated that compared with C. papaya, P. tobira and T. ahouai were more resistant. These results may be due to the fact that they were plants species of different families. The resistant plants can be studied as alternatives in the management of T. merganser.

The tomato red spider mite Tetranychus evansi Baker and Pritchard is a pest of primary importance on cultivated Solanaceae in some countries. Based on morphological characters and sequencing of a fragment of the cytochrome oxidase subunit I (COI) of mitochondrial DNA (mtDNA), the presence of T. evansi is reported for the first time in Mexico, from four municipalities (counties) in three states: Baja California, Nuevo León and Tamaulipas, on solanaceous plants, both cultivated (tomato, Solanum lycopersicum L., and potato Solanum tuberosum L.) and wild (nigthshades, Solanum cf. americanum Mill. and Solanum nigrescens Mart. and Gal.). The molecular study confirms for the first time the presence of haplotype 4 (belonging to clade I) of T. evansi in North America (Nuevo Leon state). This clade includes most invasive T. evansi populations worldwide. Although no studies have been carried out on the economic impact of T. evansi in Mexico, it is of utmost importance to recognize the presence of this species to establish sound management strategies.

The piquin chili is a wild spice widely consumed from the South United States to Central America and stands out as a source of flavonoids, essential metabolites with antioxidant properties. The concentrations of flavonoids, carotenoids, and capsaicinoids vary according to regions, maturity stages, and ripening processes. These compounds, which are known for their health benefits and industrial applications, highlight the importance of identifying ideal environmental conditions for collecting fruits with the highest contents. Comprehensive studies of the piquin chili are essential for understanding its properties for the benefit of consumers. This approach fortifies trade, contributes to resource conservation, and advances cultivated chili production.
