Understanding Citrus Pests and Their Scientific Names
This question requires matching common names of insect pests found on citrus plants with their corresponding scientific names. Let's break down each pest and its identification.
Matching Pests to Scientific Names
We are given two lists:
- LIST-I (Insect pests of citrus): A. Psylla, B. Leaf minor, C. Lemon butterfly, D. Aphids
- LIST-II (Scientific name): I. $Papulo\ demoleus$, II. $Diahorina\ citri$, III. $Toxoptera\ auranti$, IV. $Phyllocnistis\ citrella$
The goal is to correctly pair each pest from LIST-I with its scientific name from LIST-II.
Detailed Match Analysis
Match A: Psylla
Psylla, specifically the citrus psylla, is a significant pest of citrus crops. Its scientific name is $Diahorina\ citri$. Therefore, A matches with II.
Match B: Leaf minor
The citrus leaf miner is a tiny moth whose larvae create serpentine mines within the leaves of citrus trees. Its scientific name is $Phyllocnistis\ citrella$. Thus, B matches with IV.
Match C: Lemon butterfly
The "Lemon butterfly" is commonly known as the citrus swallowtail. Its scientific name is typically cited as $Papilio\ demoleus$. The provided scientific name in LIST-II is $Papulo\ demoleus$. Assuming this refers to the same pest, C matches with I.
Match D: Aphids
Aphids are small, sap-sucking insects that can infest citrus plants. Several aphid species affect citrus, including the black citrus aphid. One of the scientific names listed is $Toxoptera\ auranti$. Therefore, D matches with III.
Correct Combination
Based on the analysis, the correct matches are:
- A - II ($Diahorina\ citri$)
- B - IV ($Phyllocnistis\ citrella$)
- C - I ($Papulo\ demoleus$)
- D - III ($Toxoptera\ auranti$)
Summary Table of Matches
| Insect Pest (LIST-I) | Scientific Name (LIST-II) |
|---|---|
| A. Psylla | II. $Diahorina\ citri$ |
| B. Leaf minor | IV. $Phyllocnistis\ citrella$ |
| C. Lemon butterfly | I. $Papulo\ demoleus$ |
| D. Aphids | III. $Toxoptera\ auranti$ |
This combination corresponds to option 1.
