“…X-ray diffraction (XRD) was carried out with a Shimadzu diffractometer (model XRD6000), with CuKα radiation at 40 kV and 30 mA, carrying out the reading from 5° up to 55° 2θ at a velocity of 2° min −1 . The identification of the clay composition was performed with the aid of an energy dispersive X-ray (EDX) spectrometer (Shimadzu EDX-720) with a rhodium radiation source, operating at 15 kV (Na to Sc) or 50 kV (Ti to U) with a collimating slit of 10 mm [ 7 ].…”

“…Composites were formed through the interaction of the inorganic matrices used in this study with the pheromone rhynchophorol. The methodology described by Ramos et al [ 7 ] was applied in the preparation procedure. 50 mg of the lamellar structured Na-magadiite or zeolite L was placed in an Eppendorf ® Safe-Lock tube (2 mL/polypropylene) and 10 µL (~ 8.1 mg) of rhynchophorol was added.…”

“…Some materials have been studied for the controlled release of pheromones, including zeolites, nanoencapsulates and nanosensors [ 6 ]. The choice of the adsorbent matrix must be made cautiously, aimed at guaranteeing the maximum efficiency of the composite formed (matrix/pheromone) without contributing to the degradation of the pheromone during its preparation or storage [ 7 ]. In the selection process, some characteristics of the matrix should be observed, such as: pheromone release kinetics as close to zero as possible, low production cost and maintenance of pheromone stability.…”

“…Some structures for the pheromone controlled release matrix have been studied, such as: sepiolite clay [ 8 ]; whey protein with acacia gum for microencapsulation [ 9 ]; plastic pipette tips [ 10 ]; zeolites ZSM-5, silicalite-1, faujasite and beta zeolite [ 7 , 11 ]. The use of pheromone rhynchophorol together with mass-traps has been studied and implemented over the years, seeking to improve the efficiency of the application of this technique and enable the capture of the highest number of insects during the period of control [ 12 – 14 ].…”

A fast method for the identification and stability evaluation of the aggregation pheromone rhynchophorol, which is the main substance used for chemical communication by the beetle Rhynchophorus palmarum L., was validated. In addition, the technique was applied to the evaluation of two inorganic matrices, with the objective of using them as controlled-release devices. The analytical method showed good linearity (R2 = 0.9978), precision (CV% < 1.79), recovery (84–105%) and limits of detection (0.2 mg mL−1) and quantification (0.3 mg mL−1); in compliance with the validation legislation established by ANVISA. In the interaction study, the inorganic matrices zeolite L and Na-magadiite showed high rates of pheromone recovery without promoting its degradation for a period of 180 days, which is not reported in the literature for other matrices. The structures of the zeolite L/rhynchophorol and Na-magadiite/rhynchophorol composites showed slower release kinetics during the storage period when compared with pure pheromone, which is desirable since it extends the period of rhynchophorol release and decreases the negative effects caused by the environmental parameters.

“…Rhynchophorol [2‐methyl‐5( E )‐heptene‐4‐ol] is the major constituent of aggregation pheromone of Rhynchophorus palmarum L. (Coleoptera: Curculionidae). This beetle attacks several species of palm and, is the main vector of Bursaphelenchus (Rhadinaphelenchus) cocophilus , a nematode that causes the red ring disease in coconut plants . This pheromone has been commercialized as reservoir release systems, in two forms: (i) in Eppendorf‐type polypropylene tubes with a 1 mm diameter hole in the cap, in which the pheromone release rate is dependent of the container level and so present a nonlinear behavior, because the release rate decreases in function of time; (ii) in sachets, constituted by permeable plastic membrane to the pheromone, that usually has a constant release property, controlled by membrane composition and surface area…”

Composite membranes consisting of biodegradable poly(butylene adipate‐co‐terephthalate (PBAT) and zeolite Y (0–10 wt %) were produced by extrusion. Zeolite Y is well dispersed in the membrane up to 5 wt %, but tends to agglomerate at higher contents. The presence of zeolite Y in the composite resulted in an improvement of the thermal stability, mechanical properties, and increased the barrier properties. The interaction of the composite membranes with rhynchophorol was investigated by different techniques, showing that the semiochemical progressively lixiviates PBAT monomers, causing thermal and mechanical properties to decrease. However, no interaction seemed to occur between the rhynchophorol and the zeolite. Studies of diffusion of pheromone through membranes have shown that the addition of the zeolite Y has not contributed significantly to a decrease in the release rate of rhynchophorol, but the presence of the zeolite Y helps to increase chemical, mechanical, and thermal stabilities of the membranes. © 2017 Wiley Periodicals, Inc.

Controlling the Uptake and Release of Semiochemicals in Channel‐Type Metal‐Organic Frameworks Through Pore Expansion

Semiochemicals can be used to manipulate insect behaviour for sustainable pest management strategies, but their high volatility is a major issue for their practical implementation. Inclusion of these molecules within porous materials is a potential solution to this issue, as it can allow for a slower and more controlled release. In this work, we demonstrate that a series of Zr(IV) and Al(III) metal‐organic frameworks (MOFs) with channel‐type pores enable controlled release of three semiochemicals over 100 days by pore size design, with the uptake and rate of release highly dependent on the pore size. Insight from Grand Canonical Monte Carlo simulations indicates that this is due to weaker MOF‐guest interactions per guest molecule as the pore size increases. These MOFs are all stable post‐release and can be reloaded to show near‐identical re‐release profiles. These results provide valuable insight on the diffusion behaviour of volatile guests in MOFs, and for the further development of porous materials for sustainable agriculture applications.
