AI Technical Summary

Benefits of technology

This technology uses an insect called Pheriphorate (a type of chemical) that helps detect or prevent damage caused from harming plants during their growth process. It provides easy access through small holes on its surface with no dangerous substances like pesticides used today. Its technical effect lies in providing precise and effective ways to protect crops against attackers who may be causing economic losses due to these damaging agents.

Problems solved by technology

This patented technical problem addressed in this patents relates to finding ways for controllers or monitors against yellow palmettoweed attacks through various means such as observation from trees or cameras during their mating season. Current methodologies have been limited due to laborious manual analysis process with no comprehensive understanding of these patterns being developed at different stages of insect life cycle.

Embodiment 1

[0040] Embodiment 1: The influence of trap height on trapping effect of red palm weevil

[0041] Get the trap, place the red palm weevil to gather the pheromone lure core on the pheromone hanger of the trap; the trap is placed in the unobstructed place of forest air flow, and the hanging height is respectively 0m (surface), 1m, 2m, 5m, Count the red palm weevils trapped in the trap every week, and the results are as follows:

[0042] Table 1: Effect of trap height on trapping effect of red palm weevil (2011.06-2011.08)

[0043]

[0044] It can be seen from Table 1 that the number of red palm weevils attracted by the suspension height of 0-1m is the largest, and the effect reaches a significant level compared with 2m and 5m above the ground.

Embodiment 2

[0045] Embodiment 2: The influence of different densities of traps on trapping effect of red palm weevil

[0046] Take the trap, and place the red palm weevil aggregation pheromone lure core on the pheromone suspension frame of the trap; place the trap in a place with smooth air flow in the forest, and place it in 5 forest stands according to the density of 20m, 60m, and 100m respectively. Consistent coconut grove hanging traps, counting the red palm weevils trapped in the traps every week, the results are as follows:

[0047] Table 2: The effect of different trap densities on the trapping effect of red palm weevil (2011.09-2011.10)

[0048]

[0049] It can be seen from Table 2 that the number of red palm weevils attracted by the spacing of 60m is the largest, which is significantly different from that of the spacing of 20m and 100m, and is the most economical.

Embodiment 3

[0050] Embodiment 3: Forest monitoring effect

[0051] Adopt monitoring method of the present invention, collect and record 2011 at 3 red palm weevil monitoring points that different plots are set up in Wenchang City, Hainan Province to trap red palm weevil, the result is as follows:

[0052] Table 3: 2011-2012 Wenchang Forest Trapping Results of Red Palm Weevil Adults (2011.10-2012.09)

[0053]

[0054]

[0055] The above results are counted on a monthly basis, with the month as the abscissa, and the number of red palm weevil adults trapped in the investigation as the ordinate, making a graph, as figure 2As shown, red palm weevil adults can be lured in 12 months of a year, and the peak period of occurrence of red palm weevil is from June to August and October to November. Among them, the number of red palm weevil adults from June to August most. This can guide the prevention and control of red palm weevil in this area: taking corresponding preventive measures in Apri...

Abstract

The invention discloses a method for monitoring rhynchophorus ferrugineus through pheromones. The method for monitoring the rhynchophorus ferrugineus through the pheromones comprises the following steps that rhynchophorus ferrugineus gathering pheromone lures are placed on pheromone hanging frames of trappers; the trappers are hung on open places, with unobstructed airflow, in forest and the edge of the forest respectively in the adult rhynchophorus ferrugineus activity season, and the trappers are hung for one year; the lured rhynchophorus ferrugineus gathered in the trappers are collected weekly, the number of the lured and gathered rhynchophorus ferrugineus is recorded, and the control strategy is determined. Due to the fact that the rhynchophorus ferrugineus is monitored through the pheromones, the method for monitoring the rhynchophorus ferrugineus through the pheromones has the advantages that the steps are simple, operation is convenient, the rhynchophorus ferrugineus occurrence and development law can be monitored accurately and effectively, toxicity does not exist, and pollution is not be caused, and safety of the environment and safety of natural enemies of the rhynchophorus ferrugineus are ensured. The method for monitoring the rhynchophorus ferrugineus through the pheromones serves as one of preferred methods for modern forestry pest monitoring, and the problem that an existing rhynchophorus ferrugineus monitoring method is inaccurate, troublesome and lagging in the process of production is solved; in addition, according to the method for monitoring the rhynchophorus ferrugineus through the pheromones, operation is easy and convenient, monitoring is accurate, and the rhynchophorus ferrugineus occurrence law can be objectively reflected.
