TOMATO LOOPER

Ana Oliver — Tue, 21 May 2024 08:36:38 +0000

Ciclo biológico: En Canarias, con hasta siete u ocho generaciones superpuestas por año. Las dos épocas de vuelo predominantes son en primavera (mayo-junio) y en otoño (septiembre-octubre). En cultivos de invernadero puede presentar diversas generaciones y estar presente durante gran parte del ciclo del cultivo.

Daños: Las larvas polífagas se alimentan preferentemente de plantas jóvenes; sin embargo, los períodos de crecimiento más sensibles son desde el trasplante hasta las primeras etapas foliares, así como durante la floración y fructificación. Puede devorar completamente las hojas y afectar el fruto (pimiento y tomate). En cuanto a ornamentales, los daños estéticos reduce drásticamente el valor en el mercado.

PEACH TWIG BORER

Joan Callizo — Thu, 13 Feb 2020 06:00:33 +0000

The peach twig borer is a lepidopteran with a 10-13 mm wingspan that seriously affects drupes such as the peach, nectarine, and apricot. It can also affect plums and almonds.

Number of annual generations: normally, 3 generations a year.

Damage: feeding larvae damage buds and shoots, withering them. They also attack the fruit.

Mediterranean fruit fly

Joan Callizo — Wed, 12 Feb 2020 13:29:36 +0000

Description: the Mediterranean fruit fly is a diptera, 5-6 mm long. It is one of the most common fruit pests worldwide.

Number of annual generations: depending on the climate, there may up to 7-8 generations per year.

Damage: the damage is initially caused by the the female biting to lay her eggs, opening an entry way for fungi and bacteria. Similarly, the larvae make galleries inside the fruit when feeding. All this produces early ripening and fruit fall with the consequent loss of harvest.

The rice bore

Joan Callizo — Sat, 30 Dec 2017 16:49:08 +0000

Description: The rice borer is a lepidopteran 20-28 mm in span that causes problems in rice crops in the Mediterranean area, Asia and Australia.

Number of annual generations: in the Mediterranean area, there are generally up to 3 generations a year.

Damage: larvae pierce the stems to feed on the internal tissues of the rice plant. This significantly weakens the attacked plants, and can significantly affect the productivity of ears in strong attacks.

honeydew moth

Joan Callizo — Fri, 29 Dec 2017 18:54:14 +0000

Description: The honeydew moth is a species of lepidopteran, 1.5 cm in length, that can attack several crops such as vine, cotton, citrus, pomegranate, and persimmon, among others.

Number of annual generations: normally, 3-5 generations a year.

Damage: larvae gnaw the surface of the fruits and penetrate them. The attacked fruit changes colour precociously and falls to the ground prematurely. They can also attack the flowers of the crop.

Codling moth

Joan Callizo — Fri, 29 Dec 2017 16:55:46 +0000

Description: The Codling moth is a species of lepidopteran 15-22 mm in length of immense importance in pome fruit trees, especially apple, pear, and quince. They can also attack other crops.

Number of annual generations: normally, 3 generations a year.

Damage: the larvae penetrate the fruits, digging galleries to the core, feeding on the pulp, making them commercially unsuitable. In case of heavy pest pressure, production loss can be very high.

Olive fruit fly

Joan Callizo — Thu, 28 Dec 2017 16:57:09 +0000

Description: The Olive fruit fly is a species of lepidopteran 4-5 mm in length that only attacks the olive tree. It is very serious in the Mediterranean area, parts of Africa and western Asia.

Number of annual generations: 2 to 4, depending on the climatology.

Damage: the damage is caused by the larvae and can be direct, affecting the size and appearance of the fruit, as well as its production. It also causes indirect damage by facilitating secondary invasion of fungi and bacteria that affect the qualities of the fruit and acidify the oil.

Artichoke moth

Joan Callizo — Wed, 27 Dec 2017 15:37:50 +0000

Description: The artichoke moth is A nocturnal lepidopteran, 40-50 mm in span that damages the artichoke.

Number of annual generations: normally, a single generation, from September to the end of November and beginning of December.

Damage: the damage is caused by the larvae which, after nibbling the leaves, bore in through the veins, making galleries until they reach the stem. They can also attack the flowers. The attacked plants lose vigour, and may even die, producing a decline in production.

Oriental fruit moth

Joan Callizo — Tue, 26 Dec 2017 16:20:13 +0000

Description: The Oriental fruit moth is species of lepidopteran with a 10-16 mm wingspan. It mainly affects drupes, such as peaches, nectarine and apricot.It may also cause damage to plum and cherry trees, as well as pome fruits such as apple and pear.

Number of annual generations: normally, there are five generations a year.

Damage: caterpillars, that cause damage to shoots and fruit when feeding. The attack on shoots is very serious in young trees.

Cotton boll worm

Joan Callizo — Tue, 26 Dec 2017 06:20:42 +0000

Description: The Cotton boll worm is a species of lepidopteran with a 35-40 mm wingspan. It attacks a large number of crops such as: tomato, pepper, corn, broccoli, tobacco and cotton. It may attack many others.

Number of annual generations: normally, there are three generations a year, although depending on the weather conditions, there may be more.

Damage: the caterpillar attacks leaves, shoots and buds, although the most important damages consist of destruction of flowers and perforations in the fruit. This facilitates the entry of fungi and other pests that cause them to rot.
