“…Optical microscopic analysis portrayed that all the droplets of PO have been individually encapsulated as spherical capsules with consistent size distribution as bimodal distribution (Figure 5A). Similar morphological characteristics have also been reported in the microencapsulated oils from Annona squamosa (da Maciel et al, 2019) and Jasmine (Teeka et al, 2014).…”

“…The bioactive compounds produced in plants during secondary metabolism have been found with good insecticidal potency ( Isman, 2017 ; Lengai et al., 2019 ). However, the rapid degradation of botanical extracts caused by volatilization and photo degradation of the active principles and their low solubility towards target surfaces are considered as disadvantages for utilizing these bio-inspired pesticides ( Pant et al., 2016 ; da Maciel et al., 2019 ).…”

“…Encapsulation technique physically entraps the bioactive molecules into a protective matrix at the micro or nano range ( Karadeniz et al., 2018 ; Ferreira and Nunes, 2019 ) and thereby, improve their delivery at the desired site and time at a specific rate ( Bakry et al., 2016 ). Wall materials act as barriers to protect the core bioactive principles from degradation, evaporation and control diffusion to ensure sustained release ( da Maciel et al., 2019 ). The usefulness of encapsulation technologies in botanicals in terms of increased solubility, protection against premature degradation, and sustained release of bioactive principles have also been reported ( Bilenler et al., 2015 ; Oliveira et al., 2018 ).…”

Pongamia pinnata (L.) seed oil is effective for its insecticidal and larvicidal activities. However, its low aqueous solubility, high photosensitivity, and high volatility restrict its application for the control of agricultural pests. Encapsulation can be an effective technique to overcome such hindrances. Therefore, P. pinnata oil (PO) was extracted from its seeds and analyzed for karanjin content (3.18%) by GC-MS/MS as the marker compound. Micro-encapsulation (MC) of PO was prepared by interfacial polymerization between isocyanates and polyamine and tested for insecticidal and larvicidal activities. Bioassay of the developed formulations was tested in-vitro against 2 nd instar larvae of Bombyx mori (Bivoltine hybrid) and in-vivo insecticidal bio-efficacy was tested against aubergine aphid ( Aphis gossypii G.) and whitefly ( Bemisia tabaci G.). Various properties of micro-capsules viz., stability, size, oil content and release kinetics were examined. Average diameter of capsules (1 μm) with Zeta potential (-16 mV) was indicated by the Dynamic Light Scattering (DLS) instrument. Existence of PO in the microcapsules was confirmed by an optical microscopic study. Spectroscopic analysis revealed 87.4% of PO was encapsulated in polyurea shell. The shelf-life ( T 10 ), half-life ( T 50 ), and expiry-life ( T 90 ) of polyurea coated capsules were 11.4, 75.3 and 250.0 h, respectively. Polyurea coated PO capsule formulation showed evidence of in-vitro toxicity against 2 nd instar larvae of B. mori ( LC 50 = 1.1%; LC 90 = 5.9%). The PO formulation also exhibited 67.0–71.8% and 62.4–74.8% control of aphid and whitefly population in aubergine at 4.0% dose following 7–14 days after application. The study unveiled its significance in developing controlled release herbal formulations of P. pinnata as an alternative to harmful conventional synthetic insecticides for crop protection.

“…In addition to the aforementioned compounds, according to Ezemuoka et al [22] leaves and stem peel of A. muricata, have the presence of substances from groups, such as saponins, alkaloids, and triterpenes, which would be causing mortality of larval individuals of Aedes aegypti (Diptera: Culicidae). Likewise, Maciel et al [23] , when using A. muricata extracts to assess the mortality of Tetranychus urticae (Acari: Tetranychidae), found the presence of acetogenins, these substances act as mitochondrial electron transport inhibitors and thus affect the survival of the mites [24] . Amakiri et al [25] , using leaf and stem peel extracts of A. muricata, found insecticidal activity in Anopheles gambiae larvae (Diptera: Culicidae) due to the presence of phenolic compounds, tannins, saponins, and alkaloids.…”

Raoiella indica Hirst, 1924 (Prostigmata: Tenuipalpidae), is one of the main pest mites of palm and banana trees, causing significant damage in producing regions. Thus, the objective of this work was to evaluate the acaricidal effect of soursop peel extract (Annona muricata L.) on R. indica adults. The experiment was conducted in a completely randomized design using soursop peel extract, with 7 replications and 12 individuals of R. indica per replication. The experimental units consisted of discs of coconut palm leaves (4 cm in diameter), with cotton moistened at the bottom of the Petri dish (10.0 x 1.2 cm) and around the disc to maintain turgor and prevent mites from escaping. The application was carried out using an airbrush, connected to a calibrated compressor with a constant pressure of 1.3 psi and 1 mL of solution per plate. The acaricidal effect was evaluated 24, 48, and 72 hours after spraying. Mortality data were corrected and subsequently submitted to probit analysis (p≤0.05) using the statistical program R, with the LC50 and LC90 of the extract being calculated. The soursop peel extract at the maximum concentration used (15%) showed mortality of 80% of individuals of R. indica. The LC50 was 1.934%. It was concluded that extracts from soursop peel have acaricidal potential on R. indica in the laboratory.

“…Common methods for controlling this pest are cultural, chemical and biological methods (Powell and Lindquist, 1997;Bethke et al, 2001;Attia et al, 2013). Chemical applications are still the most extensively used method for this pest, but these chemicals can be side effect to the environment, crops and human (Nicastro et al, 2010;Meyer et al, 2009;Marsaro Júnior et al, 2012;Maciel et al, 2019). T. urticae develops resistance to pesticides because of repeated and non-selective pesticide applications; hence its outbreaks are seen often (Helle and Sabelis, 1985;Duchovskienė et al, 2009).…”

İki noktalı kırmızı örümcek Tetranychus urticae Koch örtüaltı sebzelerinde, süs bitkilerinde ve birçok meyvede anahtar zararlıdır. Üreticiler bu türü kontrol etmede genelikle kimyasal svaşımı tercih etmektedirler. Ancak bu tür sahip olduğu biyolojik özelikleri nedeniyle birçok ilaca direnç geliştimektedir. Bu nedenle bu türün kontrolünde biyolojik savaş veya entegre savaşım yöntemi önerilmektedir. Bu çalışmada bazı pestisitlerin Tetranychus urticae ve Phytoseiulus persimilis Athias-Henriot 'e etkileri incelenmiştir. Çalışmada etoxazole, bifenthrin, cyromazine ve acequinocyl aktif maddelerine sahip ilaçlar kullanılmıştır. İlaçlar her iki akar türüne de tarla uygulama dozunda larva ve ergin dönemlerine petri kabı-ilaçlama kulesi yöntemi ile uygulanmıştır. Elde edilen verilerden yararlanarak ilaçların etkisi Abbott formülüne göre hesaplanmıştır. Farklı aktif maddeye sahip ilaçların T. urticae ve P. persimilis'e karşı etkileri karşılaştırılmıştır. Elde edilen sonuçlara göre bifenthrin ve acequinocyl T. urticae ve P. persimilis'in her iki dönemine de %90-100 arasında etki göstermiştir. Etoxazole ve cyromazine ise P. persimilis''nin her iki döneminde %90' ın üzerinde ölüm meydana getirmiştir. Etoxazole uygulanan T. urticae larvalarında %100 oranında ölüm gözlenirken, T. urticae'nin her iki döneminde de cyromazine'in önemli bir etkisi olmamıştır.
