Bagrada cruciferarum

Bagrada hilaris is a species of shield bug known by the common names bagrada bug and painted bug. It could be mistaken for or erroneously referred to as harlequin bug. It is native to southeastern Africa. [1] It is known elsewhere as an introduced species, including California and Arizona, where it was first reported in 2008. [2] It is a major pest insect of Brassica oleracea crops (including cabbage, kale, cauliflower, Brussels sprouts, and broccoli), and related crucifers such as turnips, rape, and mustard. [2] The adult and nymph of the species suck sap from the leaves of the plants, causing wilting, yellowing, and stunting of growth. [3] Besides crucifers, the bugs are known on papaya, sorghum, maize, potato, cotton, caper, pearl millet, and some legumes. [2] [3] Large numbers of the bug congregate on the plants and cause extensive damage. [2] [3]

The adult bug is 5 to 7 millimeters in length, shield-shaped, and black with white and orange markings. The female, which is larger than the male, lays up to 100 oval or barrel-shaped eggs on leaves or in soil beneath plants. [3] The eggs are white when freshly deposited and turn orange over time. Within 8 days the first-instar nymph emerges. [3] It is bright orange-red and turns darker as it develops, becoming black by the last instar. [3]

The bug made a sudden appearance in Los Angeles in June, 2008, its first sighting in the Western Hemisphere. [2] It then moved into the cropland of the heavily agricultural Coachella and Imperial Valleys of California, doing damage to cole crops there, especially those grown organically. [4] By September 2014 it had reached as far north as San Mateo, Santa Cruz, Merced and Inyo counties, and all California counties to the south except Tulare County. [5] As of 2020, it was found as far north as Yolo County. [1]

Past infestations have been reported in India. [6] It was found for the first time in Chile in 2016, where it rapidly established and began generating economic loss as well as invading homes in several Chilean localities. [7] [8] [9]

A 2019 study found the eggs of invasive B. hilaris in Mexico being parasitized by a new species of parasitoid wasp, Idris elba (named after the actor of the same name). I. elba has thus been identified as a potential control agent for B. hilaris, which may benefit the broccoli crops that B. hilaris infests. [10]

Broccoli is an edible green plant in the cabbage family whose large flowering head, stalk and small associated leaves are eaten as a vegetable. Broccoli is classified in the Italica cultivar group of the species Brassica oleracea. Broccoli has large flower heads, usually dark green, arranged in a tree-like structure branching out from a thick stalk which is usually light green. The mass of flower heads is surrounded by leaves. Broccoli resembles cauliflower, which is a different but closely related cultivar group of the same Brassica species.

The Pentatomoidea are a superfamily of insects in the Heteroptera suborder of the Hemiptera order. As Hemiptera, they share a common arrangement of sucking mouthparts. The roughly 7000 species under Pentatomoidea are divided into 21 families. Among these are the stink bugs and shield bugs, jewel bugs, giant shield bugs, and burrower bugs.

Pentatomidae is a family of insects belonging to the order Hemiptera, generally called shield bugs or stink bugs. Pentatomidae is the largest family in the superfamily Pentatomoidea, and contains around 900 genera and over 4700 species. As hemipterans, the pentatomids have piercing sucking mouthparts, and most are phytophagous, including several species which are severe pests on agricultural crops. However, some species, particularly in the subfamily Asopinae, are predatory and may be considered beneficial.

The Miridae are a large and diverse insect family at one time known by the taxonomic synonym Capsidae. Species in the family may be referred to as capsid bugs or "mirid bugs". Common names include plant bugs, leaf bugs, and grass bugs. It is the largest family of true bugs belonging to the suborder Heteroptera; it includes over 10,000 known species, and new ones are being described constantly. Most widely known mirids are species that are notorious agricultural pests that pierce plant tissues, feed on the sap, and sometimes transmit viral plant diseases. Some species however, are predatory.

Pentatominae is a subfamily of Pentatomidae, a family of shield bugs. This subfamily is the largest one within the Pentatomidae, having 4937 species classified in 938 genera. Species in this subfamily are phytophages and several of them are considered agricultural pests. Some invasive pentatomines such as Halyomorpha halys and Bagrada hilaris have been considered household pests. Higher systematics of the group have been revised by Rider et al.

The brown marmorated stink bug is an insect in the family Pentatomidae, native to China, Japan, Korea, and other Asian regions. In September 1998, it was collected in Allentown, Pennsylvania, where it is believed to have been accidentally introduced. The nymphs and adults of the brown marmorated stink bug feed on over 100 species of plants, including many agricultural crops, and by 2010–11 had become a season-long pest in orchards in the Eastern United States. In 2010, in the Mid-Atlantic United States, $37 million in apple crops were lost, and some stone fruit growers lost more than 90% of their crops. Since the 2010s, the bug has spread to the nation of Georgia and Turkey and caused extensive damage to hazelnut production. It is now established in many parts of North America, and has recently become established in Europe and South America.

<span class="mw-page-title-main">Harlequin cabbage bug</span> Species of true bug

The harlequin cabbage bug, also known as calico bug, fire bug or harlequin bug, is a black stinkbug of the family Pentatomidae, brilliantly marked with red, orange, yellow and white markings. It is a major pest of cabbage and related crops in the Brassicaceae, as well as the ornamental flower cleome throughout tropical and North America, especially the warmer parts of the United States. Nymphs are active during the summer and in the tropics the bug can achieve three to six generations a year. In the northern range there is only one generation annually and the insects overwinter as adults in crop residues or field edges. Organic control involves hand-picking the insects off the plants and being especially careful to remove and destroy all the eggs, which are black-and-white striped, laid in clutches of twelve.
