Plantprovided food and biological control

The possibility of using predators for biological control of insect pests was recognized in China as far back as the fourth century AD. Hsi Han (AD 304) described in Records of the Plants and Trees of the Southern Regions how bags holding ant nests were traded in southern China. The bags were placed in citrus trees in order to protect the fruits from insect attacks. Farmers interconnected trees by means of bamboo bridges allowing ants to move between trees.

Habitat and current distribution

Historically, the Seychelles magpie-robin inhabited coastal woodland. However, that habitat has been cleared to create farmland. Very few native plants survive on Fregate Island. In response, the bird has adapted to living on plantations that grow cashews, citrus trees, coconut trees, or coffee. It can

Main Arthropod Pests And Control Strategies

Several programmes of augmentative and classical biological control by means of parasitoids and predators of the main citrus pests have been conducted in most of the northern Mediterranean citrus growing countries (Table 5). The results vary, however, several successful cases have been recorded (Viggiani, 1975 Amaro, 1992 Noyes & Hayat, 1994 Katsoyannos, 1996 Tsagarakis, Kalaitzaki, Lykouressis, Michelakis, & Alexandrakis, 1999 Kalaitzaki, 2004 Siscaro, Caleca, Reina, Rizzo, & Zappal , 2003 Siscaro, Di Franco, & Zappal , 2008 Gomes da Silva, Borges da Silva, & Franco, 2006 Jacas, Urbaneja, & Vinuela, 2006 Malausa, Rabasse, & Kreiter, 2008 Zappal , Siscaro, & Longo, 2008).

Research Gaps and Progress to Date

More recently, Hofmeyr et al. (2005) examined the effect of different release ratios of treated (T) to untreated (U) moths on the incidence of fruit damage and on the competitiveness of treated males in replicated field cage studies in South Africa. Individual navel orange trees were enclosed in large mesh cages and adult moths treated with either 150 or 200 Gy were released into the cages at ratios of 5T 1U and 10T 1U. Results showed that the number of larval entries as well as the number of F1 progeny per cage decreased significantly as the release ratio of treated moths increased. In addition, the lowest mean number of fertile F1 adult females and males was obtained from the treatment that combined the lower dose (150 Gy) and 10T 1U release ratio. This treatment also showed the lowest per generation rate of increase (less than 1 from the P to the F1 generation) suggesting that growth in the wild population would have been prevented if releases of treated moths at this dose and...

Systems Approaches as Phytosanitary Measures Techniques and Case Studies

ABSTRACT The development of export strategies for horticultural products considered to be hosts of quarantine pests follows a logical series of steps. The foundation for the process is the completion of a commodity plant pest risk assessment that satisfies the needs of the national plant protection organization of the importing country. After identifying the significant pests, a set of proposed mitigation measures is designed. Regulatory officials are increasingly using systems approaches to supplement or substitute for direct postharvest treatments in developing export strategies. The components of systems approaches can be divided into a series of five categories of measures field and production measures, preharvest measures, postharvest measures, inspection and certification measures, and shipping and distribution measures. The United States Department of Agriculture (USDA), working with the national plant protection organizations of other countries, has used the systems approach...

Fruit Production in Brazil

In the last 20-30 years, the federal and some state governments have developed many irrigation programmes in the semi-arid northeastern part of Brazil focusing on the production of tropical, subtropical, and temperate fruit crops. As a result of such actions, the north-eastern region is the largest producer in the country of mangos, table grapes, melons, bananas, Antilles cherry, and guavas. The cultivated area is continuously increasing and at the end of 2004 there were, for example, 68 455 hectares of mangos in the whole of Brazil, of which about 20 000 hectares are in the Sao Francisco Valley (Brazilian Fruits Yearbook 2005). Most of the citrus production (800 000 hectares, as well all 35 000 hectares of apples) is concentrated in the southern states of Brazil.

Main Arthropod Pests Of Citrus Culture And Pest Management In Greece

The key arthropod pests in the citrus producing areas in Greece comprise the Mediterranean fruit fly Ceratitis capitata, the California red scale Aonidiella aurantii and the citrus mealybug Planococcus citri. Outbreaks of the whiteflies Aleurothrixus floccosus and Dialeurodes citri, the scales Ceroplastes rusci and Saissetia oleae as well as the Tetranychidae mites Panonychus citri and Tetranychus urticae and the Eriophyiidae mites Aculops pelekassi and Aceria sheldoni may occur locally. The citrus leafminer Phyllocnistis citrella, aphids (Aphis spiraecola, A. gossypii, Toxoptera aurantii) and thrips (Heliothrips haemorrhoidalis, Pezothrips kellyanus) are of minor importance. The problems due to major and minor citrus pests and control measures in Greece are reviewed and Integrated Pest Management (IPM) strategies are recommended.

The Biotic Environment

A well-documented example of competitive exclusion in insects involves three species of chalcidid, belonging to the genus Aphytis, which are parasitoids of the California red scale, Aonidiella aurantii, found on citrus fruits. In the early 1900s, the golden chalcidid, Aphytis chrysomphali, was accidentally introduced into southern California, probably along with red scale on nursery stock imported from the Mediterranean region, though it is a native of China. During the next 50 years, A. chrysomphali spread along with its host throughout the citrus-growing area and exerted a reasonable degree of control over red scale, particularly in the milder coastal areas. However, in 1948, a second species, also Chinese, A. lingnanenis, was introduced in the hope of obtaining even better control of the pest. During the 1950s, A. lingnanensis gradually displaced A. chrysomphali so that, by 1961, the latter was virtually extinct, being restricted to a few small areas along the coast. However, A....

National Fruit Fly Control and Eradication Programme PROCEM

The aims of the expanded national programme are (1) to reduce fruit fly populations in the citrus-growing areas in the north-eastern region of Argentina, to levels where fruit damage is reduced to 0.5 and maintained at this level over the long term, (2) to improve control of the pests by establishing a surveillance and phytosanitary emergency response system, and by providing validation methods and technological training in the areas under control in the north-western region of Argentina, north-eastern Corrientes-Misiones provinces, and northern part of Buenos Aires province, and (3) to ensure maintenance of the pest free and low prevalence areas of Patagonia and Cuyo regions. approach to pest control throughout the national territory, involving implementation of the area-wide concept and adapting different technologies to each particular condition. It will enforce actions that have been implemented for years in Patagonia and Cuyo regions, and will expand control into new areas like...

Tools for Area Wide Management of Fruit Flies

The protection of the Fruit Fly Exclusion Zone from incursions of all pest fruit flies can be used as a model for AW-IPM on a large area basis. The Fruit Fly Exclusion Zone, covering an area of about 185 000 square kilometres (Bull 2004) is a region recognized by all Australian states, the Federal Government of Australia and some overseas trading partners as being free from species of tephritid fruit flies of quarantine significance. This region comprises about 70 of Australia's fresh citrus production as well as table grapes, pome fruit, stone fruit, tomatoes and other fruit and vegetables. Due to its being free from fruit flies, it enjoys favourable market access to other Australian states and other desirable

Pest Status And Control Measures

A forecasting warning system concerning infestation by the main insect pests of the most important crops in the country, including Citrus, operates by the Regional Plant Protection Services of the Hellenic Ministry of Rural Development and Food. Forecasting of infestation is based on meteorological data, monitoring by trapping or sampling, historical and other data sources (literature, agronomists consultants farmers files). Instructions for preventive plant protection measures are provided to the citrus growers when there is an issue of warning (Table 1).

Sex Ratios

Conditional sex allocation (where female parasitoids preferentially place female offspring in larger hosts). Since these parasitoids may be used as biocontrol agents attacking scale insect pests of citrus trees, Bernal et al. suggest that using rearing protocols that maximise the proportion of females would be economically sensible.

Case Studies

The domestic fruit fly quarantine systems approach in the lower Rio Grande River Valley is at once both a domestic and an international area-wide fruit fly control programme. The systems approach measures are designed to impact the domestic movement of citrus fruit in the USA, but at least some of the measures are applied on both sides of the Texas-Mexico border. The primary target pest of this programme is the Mexican fruit fly Anastrepha ludens (Loew). The protocol area includes five production areas in three counties of the lower Rio Grande River Valley, Hidalgo, Cameron, and Willacy counties. These three counties comprise the major citrus production area in Texas.

Costs and benefits

The cost of reared natural enemies must be judged in terms of the value of the crop protected by using the agent and in comparison to the cost of competing pest control options such as chemicals (van Driesche and Bellows, 1996). Use of T cryptophebiae against citrus pests in South Africa is economically viable even though the level of pest control is less than 60 (Newton and Odendaal, 1990). This is because the chemicals used provide only similar levels of control and are at least

Biotic effects

Food quality appears important in all these cases, but there may be related effects, for example as a result of crowding. Clearly, it can be difficult to segregate out food effects from other potentially limiting factors. In the California red scale, Aonidiella aurantii (Hemiptera Diaspididae), development and reproduction on orange trees is fastest on fruit, intermediate on twigs, and slowest on leaves. Although these differences may reflect differing nutritional status, a microclimatic explanation cannot be excluded, as fruit may retain heat longer than stems and leaves, and such slight temperature differences might affect the development of the insects.

Current Situation

Ent is the Mediterranean fruit fly Ceratitis capitata (Wiedemann), while in La Rioja province and other fruit-growing areas, the South American fruit fly Anastrepha fraterculus (Wiedemann) can also be detected (Fig. 1). Control strategies also vary with the region concerned. In the citrus-growing areas, suppression actions are the exclusive responsibility of fruit growers, while in Patagonia and


Galleries are lined with brown fecal plaster, even in such objects as dry cattle dung (cow-chips). Swarming usually occurs during the day some emerge at midday and others in the afternoon in arid regions the flights may be at dusk and following rainfall. Many are mound-building termites, and some species are well-known for their nests. A. meridionalis constructs the so-called compass mounds in North Australia. These are wedge-shaped earthen mounds that are about 3.5 m high, and have their long axis always aligned north to south. Species in arid environments include A. desertorum in Algeria, A. vilis in Saudi Arabia, A. capito in Western Australia, and A. wheeleri in southwestern USA and Mexico.
