“…Nowadays, Polyhouse is popularly used in many countries especially temperature ones such as Japan, Mexico, the northern lands, Korea, France growing vegetables in polyhouse research was conducted at May 2007.The main aim of this research was building a suitable polyhouse in hot climate regions. The polyhouse are also giving a good environment so the plants are growing properly and also produced good healthy foods [6]. There are many advantages because the plants developed in a secured surrounding like a polyhouse.…”

The solid state relay, used, has 330V ac, 10A rating on the output side and it has a triggering voltage rating of 3 to 32V dc [9]. Nowadays the recorded lodging and restaurants are using polyhouse to receive best kind of vegetables and fruits from both periodic and aperiodic season to maintain their influence.…”

Polyhouse is a structure which is constructed to provide secured and controlled environment for the proper growth of the plant. The polyhouse cultivation method provides high growth and improved productivity. To achieve proper crop management it is necessary to collect the correct information to make decisions. In the current work we considered and proposed a framework which could able to collect the information related to polyhouse atmosphere and harvest status and manage the polyhouse automatically based on the collected information. The polyhouse information is collected from different resources by using sampling method. Sampling method contains different strategies that are Simple random, stratified random, Stratified-systematic, Judgmental. Each method

“…Citrus mealybug, Planococcus citri (Risso) (Hemiptera: Pseudococcidae), is an insect pest of greenhouse-grown horticultural crops, including the following: coleus, Solenostemon scutellarioides (L.) Codd; grape ivy, Cissus rhombifolia Vahl; croton, Codiaeum variegatum (L.); and Transvaal daisy, Gerbera jamesonii H. Bolus ex Hook.f. (Cloyd 2011;McKenzie 1967;Pillai 2016). Citrus mealybug causes direct plant damage when feeding on plant leaves, stems, flowers, and fruits (Franco et al 2009;Godfrey et al 2002;McKenzie 1967).…”

“…One female citrus mealybug adult can produce more than 400 eggs during her lifetime (Copeland et al 1985). Consequently, killing the nymphs (crawlers) before they develop into adults is important for managing citrus mealybug populations (Pillai 2016). Insecticides are used to manage citrus mealybug populations in greenhouse production systems; however, management can be difficult when using insecticides (Franco et al 2009;Parrella 1999;Pillai 2016).…”

Citrus mealybug populations are difficult to manage with insecticides because the later instars and adults possess a hydrophobic waxy covering that protects citrus mealybugs from insecticide sprays, and citrus mealybugs reside in protected areas on plants that reduce exposure to insecticide spray applications (Charles 1982;Franco et al 2009;Herrick and Cloyd 2017;Venkatesan et al 2016).…”

The citrus mealybug, Planococcus citri, is an insect pest of greenhouse-grown horticultural crops. Citrus mealybug causes plant damage when feeding on plant leaves, stems, flowers, and fruits, resulting in a substantial economic loss. Insecticides are applied to manage citrus mealybug populations in greenhouse production systems. Anecdotal information suggests that mixing entomopathogenic fungal-based insecticides with insect growth regulators may be effective for managing citrus mealybug populations under greenhouse conditions. Consequently, we conducted two experiments in a research greenhouse at Kansas State University (Manhattan, KS, USA) in 2023. The experiments were designed to determine the efficacy of three commercially available entomopathogenic fungal-based insecticides [Beauveria bassiana Strain GHA (BotaniGard®), B. bassiana strain PPRI 5339 (Velifer™) and Isaria fumosorosea Apopka Strain 97 (Ancora®)] when mixed with three insect growth regulators [azadirachtin (Azatin® O), novaluron (Pedestal®), and pyriproxyfen (Distance®)] on citrus mealybug feeding on coleus, Solenostemon scutellarioides, plants. The entomopathogenic fungal-based insecticides alone or when mixed with the insect growth regulators were not effective in managing citrus mealybug populations, with <20% mortality during each experiment. In addition, all coleus plants treated with the entomopathogenic fungal-based insecticides had a white, powdery residue on the leaves. Our study demonstrates that entomopathogenic fungal-based insecticides, even when mixed with insect growth regulators, are not effective in managing citrus mealybug populations in greenhouses, which is likely because the environmental conditions (temperature and relative humidity) are not optimal for conidial germination and hyphal infection to occur. Therefore, entomopathogenic fungal-based insecticides have limited use for managing insect pests in greenhouse production systems.
