Oriental Mole Cricket – Gryllotalpa orientalis

Economic importance

Mole crickets are polyphagous. They feed on the underground parts of almost all upland crops. They occasionally cause heavy damage to the roots and basal parts of rice plants growing in raised nursery beds or upland conditions. In wetland rice, infestation occurs when there is no standing water. No recorded outbreak of this pest is known.

Geographical distribution

China, Afghanistan, Australia, Bangladesh, Bhutan, Cambodia, India, Indonesia, Japan, Lao PDR, Malaysia, Myanmar, Nepal, Pakistan, Papua New Guinea Philippines, Thailand, and Vietnam.

Morphology

Egg
The egg is oblong to oval and gray with a shiny surface. It is 2.6 mm long and 1.7 mm broad. The eggs are deposited in a hole constructed by the adult female.

Nymph
The newly hatched nymph has a white and bluish prothorax and legs. The nymph later turns gray to black with white markings. The last nymphal stage is similar to the adult except for its short wing pads.

Adult
The adult mole cricket is brownish and very plump, measuring 25-40 mm long. It has short antennae. The enlarged front legs are modified for digging.

Symptoms

Feeding on seeds and roots results in loss of plant stand in upland rice. In older plants, tillers are also fed upon.

Biology and ecology

The eggs are laid in hardened cells constructed in the soil by the females. One cell usually contains 30-50 eggs. Egg incubation varies from 15 to 40 days. The hatching nymphs feed on roots and damage the crops in patches. The nymphs have limited migrating ability and generally suffer heavy mortality. Nymphal development takes 3-4 months. The insect has only one generation per year in the temperate region.

In flooded rice fields, mole crickets are usually seen swimming on the water. Their low population density is due to cannibalism.

Host range

The host range of G. orientalis includes the following: Allium cepa L. (onion), Brassica oleraceae L. (cabbage), Camellia sinensis (L.) O. Ktze. (tea), Helianthus annuus L. (sunflower), Hordeum sp. (barley), Nicotiana tabacum L. (tobacco), Oryza sativa L. (rice), Solanum tuberosum L. (white potato), and Triticum aestivum L. em. Thell. (wheat).

Detection and inspection

The rice field can be checked for damage symptoms by using a light trap. Cut seedlings are indicative of the insect’s feeding damage.

Management

Cultural control
Standing water can help eliminate the eggs of mole crickets on the soil. In infested areas, the rice field can be flooded for 3-4 days. Construction of a raised nursery should be avoided to reduce feeding damage on seedlings.

Biological control
Natural enemies include Chlaenius sp., Labidura sp., Larra amplipennis Smith, L. luzonensis (Rohwer), L. sanguinea Williams, Liris aurulenta (Fabricius), Motes manilae (Ashmead), M. subtessellatus (Smith), M. loboriosus (Smith), and Pheropsophus jessoensis Morawitz. Beauveria bassiana (Balsamo) Vuillemin is also recorded as an important pathogen. A mermithid, Mermis nigrescens (Dujardin), is a potential agent against this insect.

Grass Cricket - Paratrigonidium bifasciatum

18-24 mm body length, body color Danhese, chest Cross backplane with brown stripes, vertical fin clock with stripes, brown Houjia legs of a ramp belt, the female with eggs. Living in the plains and low-elevation mountains, common in the shade of trees or bushes on the back of habitats, the general distribution of the island is a common species.

Blister Beetle - Mylabris phalerata

Mylabris is the dried beetle, Mylabris phalerata, Pallas (Order Coleoptera), which is abundant in China and Eastern India. The beetles are about 25 millimetres long and 9 millimetres broad; wing-cases black, with three broad, wavy, orange-yellow bands, which, when examined under a lens, are seen to bear black bristly hairs. The odour is disagreeable. M. Cichorii, which is often present in the drug, is smaller, and has brighter yellow bands, covered with a yellow downy pubescence, the hairs on the back part being black.

M. phalerata: With an oblong body, a triangular head, two large compound eyes, whippy and semented antennae. On the chest there is a pair of black leathery elytra with three orange, broad and transverse striae, and two membranous wings under the elytra. Feet in three pairs, usually dropped. Abdomen annularly segmented, covered with black hairs. Unpleasant in odour. M. cichoni: Smaller, with yellow hairs and yellow brown transverse striae on the wings. Both are acrid in taste, cold in nature, strongly toxic, and attributive to liver and stomach channels.

Frog-legged Jewel Beetle – Sagra femorata

Distribution: S. China, SE Asia
Body size: 8 - 22 mm

This is a leaf beetle (Chrysomelidae). Sub-family, the Sagrinae. The genus Sagra has over 50 different types of large stately, all have a magnificent metallic coloring and heavily thickened, while males gezähnte addition, but not appropriate for jumping back leg. The spread of about 50 species of this genus ranges from Africa, Madagascar, India, China to the world and East Asian island is once again an example of how, despite strict separation of Oriental and African animal region commonalities exist. The nature Sagra femorata takes its name from the Hinterschenkeln thickened.

Golden Edge Firefly - Lychnuris analis

Genus: Pyrocoelia

The females of this species are larviform and wingless, similar to the British glow-worm.

fireflies or lightning bugs are typically known for their conspicuous crepuscular use of bioluminescence to attract mates or prey. Fireflies produce a "cold light", with no infrared or ultraviolet frequencies. This chemically produced light from the lower abdomen may be yellow, green, or pale-red, with wavelengths from 510 to 670 nanometers.

About 2,000 species of firefly are found in temperate and tropical environments. Many are in marshes or in wet, wooded areas where their larvae have abundant sources of food. These larvae emit light and often are called "glowworms", in particular, in Eurasia. In the Americas, "glow worm" also refers to the related Phengodidae. In many species, both male and female fireflies have the ability to fly, but in some species, females are flightless.

Fireflies tend to be brown and soft-bodied, often with the elytra (front wings) more leathery than in other beetles. Although the females of some species are similar in appearance to males, larviform females are found in many other firefly species. These females can often be distinguished from the larvae only because they have compound eyes. The most commonly known fireflies are nocturnal, although there are numerous species that are diurnal. Most diurnal species are nonluminescent; however, some species that remain in shadowy areas may produce light.

A few days after mating, a female lays her fertilized eggs on or just below the surface of the ground. The eggs hatch three to four weeks later, and the larvae feed until the end of the summer. The larvae are commonly called glowworms, not to be confused with the distinct beetle family Phengodidae or fly genus Arachnocampa. Lampyrid larvae have simple eyes. The term glowworm is also used for both adults and larvae of species such as Lampyris noctiluca, the common European glowworm, in which only the nonflying adult females glow brightly and the flying males glow only weakly and intermittently.

Fireflies hibernate over winter during the larval stage, some species for several years. Some do this by burrowing underground, while others find places on or under the bark of trees. They emerge in the spring. After several weeks of feeding, they pupate for 1.0 to 2.5 weeks and emerge as adults. The larvae of most species are specialized predators and feed on other larvae, terrestrial snails, and slugs. One such species is Alecton discoidalis, which is found in Cuba. Some are so specialized, they have grooved mandibles that deliver digestive fluids directly to their prey. Adult diet varies. Some are predatory, while others feed on plant pollen or nectar.
