Pumpkin beetles, such as the red pumpkin beetle, are considered a serious threat to North American pumpkin and squash growers. It is not only the danger caused by the multiplication of these insects, but also the damage they can cause when they invade farms. The red pumpkin beetle (Rhyzopertha dominica), is a relatively large and potentially destructive insect. It is native to several countries in western Europe, but was inadvertently introduced into North America in 2004. Since then, the beetle has been detected in farms in British Columbia and Manitoba, Canada as well as several states across the United States.
Insecticide For Red Pumpkin Beetle
The adult is almost rectangular, shiny and orangey red. Its eggs are yellow and can be seen on the soil at the base of the plant. The fully grown young grub is white and legless. The pupa is found enclosed within a waterproof cocoon in the soil. Adult beetles feed voraciously on leaves, making irregular holes in the leaf lamina. The red pumpkin beetle (RPB) prefers to feed on young leaves (cotyledon stage) and so sometimes, it becomes very difficult to raise seedlings. The adult insect also feeds on the leaves of fully grown plants by scraping off the chlorophyll and giving the leaves a net-like appearance. The attacked plants may wither away, making it necessary to re-sow the crop. The larvae also cause damage by feeding on leaves and fruits in contact with the soil and by boring into the roots and stem underground. These damaged roots and stems may rot due to infection by saprophytic fungi. Young and small fruits of the infested creepers may dry up, while the bigger and mature fruits become unfit for human consumption.
Background
RPB is a serious pest of cucurbitaceous plants, except bitter gourd, which is favoured by the Epilachna beetle. The maximum damage is done when the crop is in the cotyledon stage. The first generation of beetles is therefore more injurious than the subsequent generations.
Management
- Always keep the field clean
- Sow early so that the plant passes the cotyledon stage by the time the beetles become active
- Seedlings can be saved by covering with a mosquito net
- Apply dry ash to the plants.
- Keep the field free of alternate host weeds, such as other cucurbits
- Collect adult insects from the infested leaves and kill them
- Deep ploughing of soil is recommended to expose the soil borne pests and hibernating stage of defoliators during the summer
- Using neem oil cake in the soil has been reported to kill the pest larvae
- The pest can be killed by spraying fenitrothion (e.g. Sumithion) or malathion 50EC @ 500 ml/hectare. The treatment should be applied as soon as the pest appears and repeated at 15 days interval.
When using a pesticide, always wear protective clothing and follow the instructions on the product label, such as dosage, timing of application, and pre-harvest interval.
Insecticide For Red Pumpkin Beetle
Red pumpkin beetle is a pest that attacks pumpkins, squash, cucumbers and melons. The beetles feed on the leaves of these plants and can cause significant damage to a crop. They are red or orange in color with black spots. The red pumpkin beetle is about one-quarter inch long when fully grown and has a black head and legs. The larvae are yellowish-white and have black heads.
Insecticides for red pumpkin beetles include carbaryl, acephate and malathion. Carbaryl is a carbamate insecticide that can be applied to the soil around plants or sprayed directly onto them. Acephate is an organophosphate insecticide that works by paralyzing the nervous system of insects; it should be applied only when temperatures are above 50 degrees Fahrenheit because it breaks down in cold weather. Malathion is a mixture of two chemicals: malathion itself (an organophosphate) and pyrethrins (an organic compound made from chrysanthemum flowers).
