Bactra venosana, the nutgrass borer or nutsedge borer, is a moth of the family Tortricidae. [1] It was first described by Philipp Christoph Zeller in 1847. Julius von Kennel provides a full description. [2] It has a wide distribution, from southern Europe, North Africa and Asia Minor to India, Sri Lanka, southern China, Malaya, Australia and into the Pacific where it is found on Java, Borneo, the Philippines, Taiwan, Timor, the Solomons, the Carolines and Fiji. It was introduced to Hawaii in 1925 to control nutsedge. It is now found on Kauai, Oahu, Molokai, Maui, Lanai and Hawaii.
The larvae feed on Cyperus rotundus [3] and Kyllinga species, including Kyllinga brevifolia and Kyllinga monocephala . They bore the stem of their host plant.
Affected plants first show a withering of the inner leaves, which become yellow and finally die. Early instars are pale, glassy yellowish, with a shining black head. Full-grown caterpillars are green or pale yellowish. They spin a tube of silk in the stem and in this cocoon sheds its skin to turn into a pupa of about 5–7 mm long. Adults have grayish forewings with complex brown markings. Hindwings plain grayish. [4]
Mechanical methods such as hand picking of adults and caterpillars are effective. Pheromone traps and light traps are also effective. Eggs can be destroyed biologically by using the egg parasitoid Trichogrammatoidea bactrae . [5]
Cyperus rotundus is a species of sedge (Cyperaceae) native to Africa, southern and central Europe, and southern Asia. The word cyperus derives from the Greek κύπερος, kyperos, and rotundus is from Latin, meaning "round". The earliest attested form of the word cyperus is the Mycenaean Greek 𐀓𐀞𐀫, ku-pa-ro, written in Linear B syllabic script.
Mocis frugalis, the sugarcane looper, is a moth of the family Erebidae. The species was first described by Johan Christian Fabricius in 1775. It is found in several parts of the world, including India, Sri Lanka, West African countries and other Oriental regions. The adult is a fruit piercer and a major pest of crops.
Achaea janata, the castor semi-looper or croton caterpillar, is an erebid moth, the caterpillars of which are termed 'semi-loopers' due to their mode of locomotion. It is found from the Indo-Australian tropics and subtropics, extending south to New Zealand and east through the Pacific archipelagoes to Easter Island. It is a major pest of castor throughout the world.
Agapeta zoegana is a species of moth known as the sulphur knapweed moth and the yellow-winged knapweed root moth. It is used as an agent of biological pest control against noxious knapweeds, particularly spotted knapweed and diffuse knapweed.
Acleris variegana, the garden rose tortricid moth or fruit tortricid, is a moth of the family Tortricidae. It has a Palearctic distribution. The moth flies from July to September mainly at night and is attracted to bright lights. The larvae feed on various trees and shrubs including rose and apple.
Archips xylosteana, the variegated golden tortrix or brown oak tortrix, is a moth of the family Tortricidae.
Crocidosema plebejana, the cotton tipworm, is a tortrix moth, belonging to tribe Eucosmini of subfamily Olethreutinae. It is found today all over the subtropical and tropical regions of the world and even occurs on many oceanic islands – in Polynesia and Saint Helena for example – but has probably been accidentally introduced to much of its current range by humans. In addition, it is also found in some cooler regions, e.g. in Europe except in the east and north; this is probably also not natural, as it was, for example, not recorded in the British Isles before 1900.
Bactra is a genus of moths belonging to the subfamily Olethreutinae of the family Tortricidae.
Cryptophlebia ombrodelta, the litchi fruit moth or macadamia nut borer, is a moth of the family Tortricidae. The species was first described by Oswald Bertram Lower in 1898.

Maliarpha separatella, the African white stemborer, is a species of moth of the family Pyralidae. A worldwide paddy pest, it is found throughout African countries of Cameroon, Mali, Réunion, Madagascar, South Africa, and many Asian paddy cultivating countries such as Myanmar, India, and Sri Lanka. Though they are reported from China and Papua New Guinea, they are also known to attack sugarcane.
Sesamia inferens, the Asiatic pink stem borer, gramineous stem borer, pink borer, pink rice borer, pink rice stem borer, pink stem borer, purple borer, purple stem borer or purplish stem borer, is a moth of the family Noctuidae. The species was first described by Francis Walker in 1856. It is found from Pakistan, India, Sri Lanka, Myanmar to Japan and the Solomon Islands. A polyphagous species, it is a major pest in many crops worldwide.
