“…According to Jeppson et al (1975), P. latus is very demanding for quality on colonized host, showing strong preference for young and tender plant tissues. Jovicich et al (2004) stated that at the time when the apical leaves have slight injuries, the population of P. latus is already high enough to cause real damage and high levels of effective control is difficult to achieve. Therefore, management strategies, where problems with this mite are frequent, should be whenever possible, based on preventing or controlling infestations right after plant germination.…”

Despite the continued efforts on the search for different genotypes, Capsicum annuum (L.) is quite susceptible to attack by pest arthropods, especially the broad mite Polyphagotarsonemus latus Banks. Thus, the host preference, population growth and the injuries assessment of P. latus was studied on six C. annuum genotypes used in Brazil (Atlantis, California Wonder, Impact, Palloma, Rubia and Tendence). Host preference was accessed in choice tests, pairing the several genotypes, and the population growth was observed through non-choice tests in laboratory. The injuries assessments were evaluated in the greenhouse, comparing the injury level among the six genotypes. The results indicate that California Wonder and Palloma genotypes were more preferred by P. latus, and Impact and Tendence were less preferred. P. latus presented positive population growth rates (ri) on all the genotypes, however, Palloma and California Wonder showed the highest values of population growth rate (ri = 0.344 and ri = 0.340, respectively), while Impact had the lowest value (ri = 0.281). All the evaluated C. annuum genotypes showed low tolerance to P. latus and exhibited several injuries, but there was no statistical difference between them. California Wonder had the highest average number of mites/leaf (57.15), while Impact and Tendence obtained the lowest values (36.67 and 35.12, respectively) at the end of the evaluation period. The total average of injuries notes at the end of the bioassay did not differ between the genotypes. The number of mites/leaf was growing for the injury scale to the note 3.0, but when the injury scale approached the note 4.0, there was observed a decrease in the number of mites/leaf for all the genotypes.

“…Broadmites (Polyphagotarsonemus latus), twospotted spider mites (TSM, Tetranychus urticae), western-flower thrips (Frankliniella occidentalis), cotton or melon aphids (Aphis gossypii), and whiteflies (Bemisia tabaci) are the most prevalent pests in the Florida greenhouse vegetable industry. Of these five species, broadmites are the most difficult to detect because of their small size (body length is between 100-200 microns) and detection generally occurs once feeding has already damaged the apical growth (Jovicich et al, 2004a). Since infestation can easily occur during transplant production, it is recommended that plants commonly affected by broadmites be treated preventatively.…”

“…Since infestation can easily occur during transplant production, it is recommended that plants commonly affected by broadmites be treated preventatively. Applications with pesticides, such as sulphur, may cause phytotoxicity to young transplants and is thus discouraged (Jovicich et al, 2004a). Preventative releases of the predatory mite (PdM) Neoseiulus californicus, have been shown to effectively control broadmites in pepper when released at a rate of 2 PdM per plant 6 days prior to transplanting or a rate of 4 PdM per plant at 6 days prior to, at, or 4 days after transplanting (Jovicich, 2007).…”

The primary arthropod pests associated with greenhouse vegetable production in Florida are: broadmites, spider mites, thrips, aphids, and whiteflies. The primary disease is powdery mildew. The objective of this research was to identify pesticide-free control measures of the most common arthropod pests of the Florida greenhouse vegetable industry and to recycle water and nutrients, safely without disease pressure. Broadmites and spider mites are controlled with the predatory mite N. californicus if released prior to or at transplanting. Aphids and whiteflies are controlled with the parasitic wasps Aphidius colemani and Eretmoserus sp. or Encarsia sp., respectively, which can be released and/or reared on banker plants. Thrips populations can be reduced with generalist predators such as Orius sp., but more recently a predatory mite, Amblyseius swirskii has been reported to be effective. Disease resistant cultivars are preferred, however, cultural controls such as isolation from disease pressure, anti-condensation coverings, fans and aeration and bio-friendly fungicides are necessary. Regular scouting and correct identification of pests is key to pest management and implementing biological control. Plants were fertigated in a hydroponic system using pine bark or perlite medium in nursery pots. Drainage water was collected, sanitized, adjusted for EC and pH when necessary, then recycled to the plants. A sustainable, pesticide-free environment is not only safer for the plants and produce being grown, but also, employee safety and efficiency can be increased since re-entry periods that delay worker production are eliminated.

“…BMs attacking bell peppers can be found in protected structures, including high tunnels, causing the development of stunted plants that produce small and poor-quality fruits or no fruit ( Ibrahim and Low 1998 , Jovicich et al 2004 ). Research on A. swirskii has shown it is successful controlling BMs ( Van Maanen et al 2010 , Onzo et al 2012 ), but only few studies have assessed its performance under field conditions ( Abou-Awad et al 2014a , b ).…”

Amblyseius swirskiiAthias-Henriot (Acari: Phytoseiidae) is a predatory mite used to control thrips (Thysanoptera), whiteflies (Bemisia tabaci Genn., Hemiptera: Aleyrodidae), and broad mites (BMs) (Polyphagotarsonemus latus Banks, Acari: Tarsonemidae). Dispersal of A. swirskii, using the ornamental pepper “Explosive Ember” as a banker plant was evaluated for control of BMs in high-tunnel peppers. Open-canopy plants (5 weeks old) versus closed-canopy plants (10-weeks old) were used to evaluate the effect of plant connectedness in A. swirskii dispersal, in the presence (two females per plant) and absence of BMs. Plots consisted of a single central banker plant and four bell peppers extending linearly north and south. Sets of all treatments were destructively sampled 1, 4, and 7 days after releasing A. swirskii. Within 24 h, A. swirskii dispersed four plants away from the banker plants (1 m), regardless of the state of the canopy. Canopy connectedness did increase the presence of A. swirskii on the crop plants. Predatory mite numbers on closed-canopy treatments doubled within the 7-day sampling period, whereas no significant increase was observed on open-canopy treatments. The presence of BMs had no significant effect on the movement of A. swirskii. The results suggest further experiments with A. swirskii and banker plants for control of BMs is warranted.
