Trap Cropping

Companion planting is a well-known strategy to manage insect pests and support a natural enemy population through vegetative diversification. Trap cropping is one such type of special companion planting strategy that is traditionally used for insect pest management through vegetative diversification used to attract insect pests away from the main crops during a critical time period by providing them an alternative preferred choice. Trap crops not only attract the insects for feeding and oviposition, but also act as a sink for any pathogen that may be a vector. Considerable research has been conducted on different trap crops as companion plant species to develop improved pest management strategies. Despite this, little consensus exists regarding optimal trap cropping systems for diverse pest management situations. An advantage of trap cropping over an artificially released natural enemy-based biological control could be an attractive remedy for natural enemies in cropping systems. Besides, many trap crop species can conserve natural enemies. This secondary effect of attracting natural enemies may be an advantage compared to the conventional means of pest control. However, this additional consideration requires a more knowledge-intensive background to designing an effective trap cropping system. We have provided information based on different trap crops as companion plant, their functions and an updated list of trap cropping applications to attract insect pests and natural enemies that should be proven as helpful in future trap cropping endeavors.

 The eulophid wasp, Anselmella malacia Xiao & Huang, 2006 (Hymenoptera: Eulophidae), is reared from fruits of the water apple, Syzygium samarangense, and is reported as an important phytophagous developing as seed-eaters of Syzygium species in Malaysia. Analysing specimens of pest insects infested inside of pear-shaped fruits of the cultivated water apple, S. samarangense, in Dong Thap Province, South Vietnam, a total of four insect species were recorded as the important pests for fruits of six varieties of the cultivated water apples. The hymenoteran wasp, A. malacia, is recorded for the first time from Vietnam. Further evidence is needed to prove A. malacia being an invasive pest in Vietnam. The associated hymenopteran parasitoid assemblage with the fruit infested insect pests is also provided.

This study evaluated the occurrence of lepidopteran pests on millet cultivated in off-season in the state of Mato Grosso, Brazil. Larvae were collected from May to July 2013 in an area of 145 hectares located in Tangará da Serra, MT. After being collected, caterpillars were kept in the laboratory and fed an artificial diet until the pupal stage. After emergence, adults were dry mounted, identified, and deposited in the entomological collection of Embrapa Cerrados, Planaltina, Distrito Federal, Brazil. Adults obtained from 117 caterpillars were identified as Mocis latipes (Guenée), Spodoptera frugiperda (J.E. Smith), Helicoverpa armigera (Hübner), H. zea (Boddie), Mythimna (Pseudaletia) sequax Franclemont, Urbanus proteus (Linnaeus), and Leucania latiuscula Herrich-Schäffer. This study describes the first record of lepidopteran pests on millet plants in the state of Mato Grosso, and the incidence of lepidopterans in the system that uses millet as cover crop represents a risk of the occurrence of insect pests on subsequent crops on the straw of this grass.

The present paper reports the occurrence of insects damaging Eucalyptus in nursery stage. Out of nine insects recorded, seven species observed as occasional defoliating species, viz. Achaea janata (Linnaeus) (Lepidoptera : Noctuidae), Catapsilia crocale Cramer (Lepidoptera : Pieridae), Dasychira grotei Moore (Lepidoptera : Lymantriidae), Eurema hecabe Linnaeus (Lepidoptera : Pieridae), Hyposidra talaca (Walker) (Lepidoptera : Geometridae), Lymantria sobrina Moore (Lepidoptera : Lymantriidae) and Spodoptera litura (Fabricius) (Lepidoptera : Noctuidae), one rare sap-sucking species, Chrysocoris purpureus Westwood (Heteroptera : Pentatomodae) and one gall making species, Leptocybe invasa Fisher & LaSalle (Hymenoptera : Eulophidae). Among the nine species collected, six defoliators and one sap sucker are new addition to the Eucalyptus entomology. Further, H. talaca is the first record of occurrence on Eucalyptus in India. On the basis of percentage infestation/damage caused by above insects, L. invasa, commonly known as blue gum chalcid wasp, was recorded only as a key insect pest in nursery stage of Eucalyptus. The results have been discussed in the light of the present observations.

The first record of red scale in Kenya Colony in the file of the Entomological Laboratory is for 1914, on citrus. It is known that the scale has been brought into the country in at least one consignment of citrus, which, being accompanied by a certificate from the country of origin that the plants were free from insect pests, was allowed to enter the country under the Plant Import Regulations then in force, without being inspected. It seems, therefore, likely that red scale is not indigenous to the country, but an introduced pest.

Currently Parapanteles Ashmead (1900) has been recorded only from the Australian and American continents. However, in this publication we describe Parapanteles rooibos n. sp. from the African continent. We also provide information about its ecology and biology. The species may ultimately prove to be an important natural enemy of Isturgia exerraria (Prout) (Lepidoptera: Geometridae: Ennominae), an herbivore of the commercially produced shrub Aspalatus linearis (Fabaceae), from which rooibos tea is made. A hyperparasitoid, Pediobius sp. (Hymenoptera: Eulophidae), is recorded. A key to the four currently known Parapanteles species is included to facilitate species identification.

Ecological Basis

Contrary to a common conception, employment of biological control of weeds is fundamentally the same as the employment of biological control of insect pests. The goal in each case is not eradication but the reduction of pest populations to non-injurious levels. The ecological relationships which apply in the regulation of any organism by natural enemies in the undisturbed natural scene also apply when we attempt to introduce a natural enemy not already present. While it is true that our work has an economic or applied objective, the pursuit of objectives in biological control in general takes us deeply into fundamental considerations – fundamentals which constitute the broad science of ecology.
