The following specification particularly describes the nature of the invention and the manner in which it is to be performed.

TECHNICAL FIELD OF INVENTION
The present invention describe herein, relates to crop protection device, and more particularly, to an environmentally pest controlling device methodically designed to monitor, trap and control Red Palm Weevil (RPW) pest in agricultural fields.

BACKGROUND OF INVENTION
Coconut plantation, Dates plantations and Oil Palm plantations are valuable agricultural profession for farmers and for many communities in the Middle East, North Africa, and other parts of the globe, significantly contributing to the world economy. Dates have been a basic staple food for centuries and are now an important economic crop. More than seven million tons of dates produced annually. In 2020 global coconut production for copra oil is estimated as 5.86 million Metric Tons, palm kernel, Oilseed is estimated as 20.03 million Metric Tons as per USDA Oilseeds: World Markets and Trade, 2022 report and world production of dates was 9 million tons.
RPWs, commonly known as Asian red palm weevils, are large, polyphagous insects (usually =30 mm long) belonging to Rhynchophorinae, a subfamily within Curculionidae (Coleoptera) (Borror et al. 1964). The Asian species include, R. ferrugineus, R. vulneratus (Panzer), R. distinctus (Wattanapongsiri) R. lobatus (Ritsema), and R. bilineatus (Montrouzier) (Murphy and Briscoe 1999).
The RPW, R. ferrugineus (Coleoptera: Curculionidae), is an internal tissue borer reported to infest 40 different palm species including coconut trees, oil palm trees and dates palm trees worldwide in diverse Agro ecosystems (Malumphy & Moran 2009). Red Palm Weevil silently infests and attacks young, soft palm trees that are less than 20 years old, without giving any major clues of infestation to the farmers and destroys the infested trees within six months of infestation.
The weevil causes severe economic losses to the tune of millions of dollars annually, through the lost harvest due to pest infestation and for cost incurred to control pest. In Gulf countries and the Middle East, $8 million of revenue lost each year, and spent for the removal of severely infested trees alone. In Italy, Spain and France, the combined cost of pest management, eradication and removal / replacement of infested palms, and loss was around €90 million in 2013. The cost of economic loses estimated to increase to €200 million by 2023 if a rigorous containment program is not in place.
In India, the pest infestation is seen throughout coconut and oil palm growing area (18 states) and it causes 25% harvest loss due to infestation. As per study, 3-15 years old palms are susceptible to pest attack. To control these pests, farmers adopt unconventional and unscientific practices by using ineffective chemical pesticides, which are used irrationally and in massive quantities. Regular insecticidal sprays and stem injections are required to keep the pest population in control.
Coconut growers in various localities resort to almost regular insecticidal spray and trunk injections, poisoning the tree and harvest. Two to three sprays, 40ml to 100ml of trunk injection on both sides and root feeding of Monocrotophos is believed to be effective in controlling the pests. However, these methods result in tree poisoning and after root feeding of pesticides, up to 45 days nuts must not be harvested. Reginald (1973) suggested that natural enemies do not play an important part in controlling R. ferrugineus. There were attempts in the laboratory and in fields using the predacious Chelisoches morio in India (Abraham & Kurian, 1973) to control the pest, but failed.
However, there are no effective methods to control this economically significant pest. Scientists are researching day and night to control the infestation of this pest using pheromones. The Red Palm Weevil’s (RPW) male produced aggregation pheromone, Ferrugineol (4-methyl-5-nonanol), was identified and first synthesized in the early nineteen nineties (Hallett et al., 1993) and since then, pheromone technology has been incorporated in the management strategy against Red Palm Weevil (RPW) to monitor and mass trap adult weevils in several countries (Faleiro 2006). Addition of 4-methyl-5- nonanone in lesser amounts to Ferrugineol significantly enhances weevil captures when used in the field through food baited traps (Abozuhairah et al., 1996). Red Palm Weevil (RPW) adult captures in pheromone traps are female dominant (male: female ratio of 1:2). Trapped female weevils are young, gravid, and fertile (Abraham et al., 2001; Faleiro et al., 2003) which increases the likelihood that mass trapping will suppress Red Palm Weevil (RPW) population in fields.
Infestation of the red palm weevil has a tremendous impact not only on the produce of the palm but also on economy of the society. “To reduce this infestation, farmers have adopted the use of pesticides and other chemicals to their crop fields either by spraying or directly injecting them to the trunk, stems and roots, there by poisoning the plants which have sudden effect on pests which is a known fact, but gradual ill effects of these pesticides on ecosystem which is an unknown fact”. To avoid these hazard effects, Integrated Pest Management (IPM) using biologically produced safe, harmless, and eco-friendly pheromones molecules is the best practice we can put in place. Difficulty in detecting initial stages of infestation and manifestations of red palm weevil (RPW) makes it a global challenge to prevent and control its infestation.
During March 2017, the Food and Agricultural Organization of the UN through its ‘Rome Declaration’ called for the urgent need to combat RPW by collaborative efforts and commitments at the country, regional and global levels to stop the spread of this devastating pest. There exist gaps and challenges in almost all the components of the current RPW - Integrated Pest Management (IPM) strategy, particularly with regard to early detection, developing and implementing phytosanitary measures, lack of effective biological control agents in the field, which have made RPW control and eradication extremely difficult.
Usually, pest infestation is detected only after the palm tree has been severely affected and damaged.
At present, no effective prophylactic methods or effective method for controlling or trapping the pest Red Palm Weevil (RPW) is available.

In this prevailing situation, where there is no effective method available to monitor and control RPW pest, the present invention offers an eco-friendly, safe as well as an affordable solution to the farmers of coconut plantations, oil-palm plantations, and dates plantations. The Present invention effectively overcomes the drawbacks of the trivial, traditional, antiquated, and ineffective methods used to control the RPW pest and offer an effective solution for the control of RPW pest and helps farmers to protect their crops and plantations from the infestation and to increase the yield by reducing the harvest loss due to RPW pest infestations.

In accordance with the embodiments discussed herein, a crescent wing trap for monitoring and trapping of Red Palm Weevil (RPW)) is disclosed. Referring to Fig. 1, the crescent wing trap (700) is disclosed when installed on trunk of a tree to effectively monitor and trap RPW.

An aspect of the present disclosure relates to an eco-friendly Red Palm Weevil trapping device with bio-degradable lure (containing both pheromones and kairomones) which is effectively used for monitoring of the RPW pest infestation as well as for the effectively Mass Trapping and controlling of RPW. The Crescent Wing trap is methodically designed by considering RPW pest flying pattern, color perception, attraction (chromotaxis) and its biological behavior influenced by the pheromone and kairomone signal (chemo signal) concluded with in-vitro studies, in-vivo experimental studies and agriculture open field efficacy studies.

The crescent wing trap comprises two main elements (A) trap and (B) a Bio-degradable, activated cellulose matrix lure impregnated with formulated pheromones and kairomones.

In accordance with an embodiment of the present invention, Fig. 2 illustrates that the RPW trap (700) consists of following components:
1. Crescent base bowl (311) – It is a hollow extrusion of intersection of major arc and minor arc of two variant circles (different diameters). The inner surface is smoothened to prevent trapped insect from crawling out i.e. preventing escape of trapped insects. The outer surface is made rough, as it enables RPW to crawl and fall into the crescent bowl under the influence of lure. At the time of operation, the Crescent base bowl (311) will be filled with water to immobilize the insects. The Crescent base bowl (311) has protrusions (212) with central hole (213) and having circular protrusion (211) at center for the assembly for interlocking with built-in push-fit rivet of the vertical wings, along with notches (216) for draining of excess water.
