Fumigant toxicity of Ethyl Formate (EF) against four major cocoa storage pests was carried out on a semi commercial trial of two metric ton of cocoa beans under sheet without forced air circulation. The EF with concentration from 76-380 g L-1 were studied against pupae, larvae and adult of Cocyra cephalonica and Ephestia cautella (moth) and Triboli...
A series of Ethyl formate (EF) concentration from 76 to 380 gL were applied onto 2 metric tons of 1 dry cocoa beans. The fumigations were carried out on a semi commercial storage condition in a field warehouse. Dry cocoa beans treated with EF were analyzed for pH, titrable acidity and microscopic scanning with environmental scanning electronic micr...
Sejumlah 1,153 individu pepatung yang terdiri daripada individu dewasa, larva dan exuviae yang mewakili 46 spesies daripada sembilan famili Odonata telah berjaya dikutip dan direkodkan di Hutan Lipur Lubuk Semilang, Langkawi daripada April 2013 hingga April 2014. Libellulidae (suborder Anisoptera) menyumbang jumlah spesies yang paling tinggi iaitu...
Delphacidae (planthopper) and Cicadelidae (leaf hopper) population are main insect pests of rice plants. As phloem-feeder insects, their population abundance can be influenced by rice growth development and abiotic factors such as temperature and humidity. This study was done to examine the temporal abundance of Delphacids and Cicadelids between ri...
Heavy infestation on stored products by insect pests is common and abundant in cocoa warehouses in hot and humid condition. Fumigation using methyl bromid or phosphine is commonly used to eleminate the insects infestation but concern on the their residual toxic effects to the stored cocoa and also environment has prompted us to find alternative way...
The leafhopper (Homoptera: Delphacidae) and planthopper (Homoptera: Cicadelidae) are considered as important rice pest in Asia including Malaysia. As phloem-feeders, they can cause loss to rice growth development and their population abundance is thought to be influenced by rice growth stages. This study was conducted to examine the population of D...
The Coconut Leaf Beetle, Brontispa longissima (Gestro) (Coleoptera: Chrysomelidae) is one the most serious pests of coconut palms. This study was aimed to investigate the field incidence of Brontispa longissima infestation at Department of Agricultural, Parit Botak, Batu Pahat, Johor. B. longissima were collected from infested coconut and other pal...
In this paper, 25 genera and 38 species under 10 tribes (Alomyini, Compsophorini, Goedartiini, Heresiarchini, Ichneumonini, Ischnojoppini, Joppocryptini, Listrodromini, Oedicephalini and Platylabini) of the subfamily Ichneumoninae housed in the Centre for Insect Systematics, UKM and Raffles Museum of Biodiversity Research (National University of Si...
Emulsion oil-in-water was prepared with combination of emulsifiers (non-ionic surfactants) following the HLB (hydrophylic-lipophylic balance) method developed by Griffin. The emulsions were prepared at HLB 10, 11, 12, 13 and 13.6 consisting blend of non-ionic emulsifiers fatty acid ethoxylate with 20 moles bound ethylene oxide and Dehydol LS 1 with...
The effects of various concentrations of honey and sucrose on the longevity and fecundity of Apanteles metesae (Nixon), an endoparasitoid of oil palm bagworm, Metisa plana (Walker) (Lepidoptera: Psychidae) were studied in the laboratory. Our results showed that there were a significant difference (p<0.05) in the longevity of A. metesae fed on vario...
The study was carried out to determine the effect of diets containing different parts oi Andrographis paniculata on cumulative gas production, dry matter digestibility, methane and volatile fatty acids production in goats using in vitro gas production technique. The leaves, stems and roots oi Andrographis paniculata (AP) were analysed for total pol...
This paper reports the preliminary finding on the assessment and taxonomic status of Pseudophyllinae bush-crickets ftom Malaysia. A total of 61 species were recorded, of which 45 species belong to 21 genera are from Peninsular Malaysia, while 29 species belong to 17 genera are from Sabah and Sarawak. A list of Pseudophyllinae bush-crickets from Mal...
A preliminary study on selected insect communities of Tasik Chini was conducted from 27th May to 2nd June 2004 along three trails namely trail to Sg. Gumum, trail to Kampung Melai and trail to old tin mining area. A total of eight Malaise traps were installed along the trail to Sg. Gumum while sweeping net and 10 yellow pan traps per trail were use...
The genus Podopterocus Banks has been known only from male specimens and has been characterized by the thickened first antennal flagellomere and the expanded hind tibia. The genus Dinopsocus Banks has been characterized by the thickened first antennal flagellomere. Detailed morphological examinations and brief molecular-based identification (only f...
The presence of weeds has an effect on the insect abundance in the crop ecosystem, which affects the pest management practices. This paper reports the abundance of Asiatic corn borer, Ostrinia furnacalis Guenee, egg masses and parasitism by its native egg parasitoid, Trichogramma papilionis Nagarkatti, in two vegetational regimes namely weedy (plot...
A study on diversity of ichneumonid wasps in the Sungkai Forest Reserve was studied from June to September in 2000. To investigate the horizontal diversity, samplings were taken using Malaise traps placed along three transect lines started from forest edge to 600 m into the forest interior. For the vertical diversity study, traps were installed at...
The preliminary study on differential abundance and diversity of ichneumonids and braconids of star fruit and oil palms was conducted between July and November 1999. The braconids species seemed to be more abundant and diverse than the ichneumonids irrespective of the two agricultural habitats. This indicates a differential habitat preference betwe...
Effects of different diets on the development of scuttle flies larvae, Megaselia scalaris (Loew), pupae and adult emergence and longevity were studied. The diets (treatments) used were nutrient agar (NA, control), casein agar (CA), tissue extracts of the round snail, Bradybaena similaris (Fer.), + NA, tissue extracts of the giant African snails, Ac...
ABSTRAK Satu kajian telah dijalankan terhadap perbezaan kesan tumbuhan makanan pada perkembangan laroa dan pupa rama-rama belakang intan (DBM) (Plutella xylostella L.) kelakuan memakan oleh laroa dan penghasilan telor oleh serangga dewasa betinanya.

The objective of this study was to apply a microscopic lesion scoring system for assessing the severity of experimental coccidiosis. To accomplish this objective, we examined the effects of varying doses of E. maxima in chicks by comparisons of gross and microscopic lesion scores, body weight gains, feed conversion ratios and faecal oocyst counts....
Comparisons were made between microscopic lesion scores (MLSs) and gross lesion scores (GLSs) in sections from small intestine of broilers during three routine coccidiosis screenings. The duodenal and jejunal GLS were determined and recorded by different evaluators. During each screening, 2-cm sections of duodenum and jejunum were collected, and se...
