Abstract: The parasite, Plasmodium needs an insect vector (mosquito) and a vertebrate host (human) to successful malaria transmission. The parasite use the vertebrate hosts for their asexual reproduction and insect host for sexual multiplication. In order to know the mechanism of disease transmission, knowledge about the possible interactions causes by the three components, vector, parasite and host is important. The mosquito feeding behaviour greatly contributes in the rate of malaria transmission. To assist the rate of transmission of malaria, the parasite, Plasmodium completes a complex developmental stage in the mosquito. In the mosquito the parasite, passes complex developmental stages and ensuing changes into three important forms of their life cycle: ookinete, oocyst and sporozoites. This review study concludes that, the interactions among vector, parasite and host in terms of reproductive behaviour and blood-feeding behaviour helps in transmitting malaria to the vertebrate hosts mainly, human being.Progressive Agriculture 27 (2): 168-174, 2016

Abstract: Plants respond to insect attack by releasing blends of volatile chemicals that attract their herbivores’ specific natural enemies, while insect herbivores may carry endosymbiotic microorganisms that directly improve herbivore survival after natural enemy attack. Here we demonstrate that the two phenomena can be linked. Plants fed upon by pea aphids release volatiles that attract parasitic wasps, and the pea aphid can carry facultative endosymbiotic bacteria that prevent the development of the parasitic wasp larva and thus markedly improve aphid survival after wasp attack. We show that these endosymbionts also attenuate the systemic release of volatiles by plants after aphid attack, reducing parasitic wasp recruitment and increasing aphid fitness. Our results reveal a novel mechanism through which symbionts can benefit their hosts and emphasise the importance of considering the microbiome in understanding insect ecological interactions.

Abstract: Traditional there are two strategies to handle pest problems in crop production, either dependence on non-chemical agricultural practices (such as cultural, mechanical, biological practices etc.) or reliance on existing natural pest control mechanisms. Intercropping is a cultural non-chemical agricultural practice where two or more crops are grown on the same field in a year with different cropping patterns. In this multiple cropping system, bio ersity and pest suppression are increased. Bio ersity can restore the natural elements of agro ecosystem because almost all favorable elements of natural enemies are available in ersified agro ecosystem. Energy intensive modern technology in agriculture is one of the vital causes for loss of bio ersity. In intercropping system biological pest control method can be ensured with higher level of crop ersity instead of energy intensive agriculture. Intercropping provides different benefits on pest management with two available hypotheses or mechanism. One of the hypotheses is the ‘resource concentration hypothesis’ and another is the ‘natural enemies hypothesis’. Intercropping, directly and indirectly, influences to increase bio ersity which results in reduction of pest densities in crop fields. As a result, less expense for use of pesticide is required and finally higher yield also add some financial benefits. Intercropping system utilizes inherent ability of plant to protect pests. Therefore further knowledge about genotypic crop ersity, ersity of natural enemies, chemically-mediated mechanisms of Volatile Organic Compounds (VOCs) will be effective for further improvement of intercropping system for greater benefits.

Abstract: The “Push–Pull” strategy is an effective, efficient, and powerful tool in integrated pest management (IPM) that is combining several behaviour-modifying stimuli to control cereal stem borers and the noxious weed Striga in cereal-based farming systems in Africa. This technology involves driving away from the cereal stemborers from the main crop by using stimuli of repellent intercrops (push) that mask host apparency and simultaneously stemborers are attracted by highly apparent and attractive stimuli from trap plants (pull). The fodder legume, Desmodium (D. uncinatum and D. intortum), and Molasses grass (Melinis minutiflora) are used as the repellent intercrop, which is repugnant to stemborer moths. On the other hand, Napier grass (Pennisetum purpureum) and Sudangrass (sorghum vulgare sudanese) is planted as a border crop used as the trap plant (pull). Chemicals that are released by the roots of the Desmodium intercrop induce abortive germination of seeds of noxious Striga weeds, providing very effective control of this weed. Napier grass and Molasses grass also provide high-value animal fodder that facilities milk production, ersifying sources of farmers’ income. Besides, this technology helps to improve soil fertility and prevent soil erosion that leads to increased grain yield in the future. Chemicals that are released by the roots of the Desmodium intercrop induce abortive germination of seeds of noxious Striga weeds, providing very effective control of this weed.

Abstract: Prey consumption efficiency of the wolf spider, Pardosa pseudoannulata (Boesenberg and Strand) preying on brown planthopper (BPH), Nilaparvata lugens (Stål), green leafhopper (GLH), Nephotettix virescens (Distant) and drosophila, Drosophila melanogaster was investigated in the laboratory of the Department of Entomology, Bangladesh Agricultural University, Mymensingh during the period from June 2008 to April 2009. Depending on the instars and maturity, the spiders were grouped into four different age classes, namely Class I (3rd and 4th instars), Class II (5th and 6th instars), Class III (7th and 8th instars) and Class IV (egg bearing female). When the spiders of each class was supplied with sufficient number of BPH, GLH and Drosophila then the order of the prey consumption of Class I spider was BPH drosophila GLH and the order of the prey consumption of Class II, Class III and Class IV were BPH GLH drosophila. But in two cases BPH was highly preferred over drosophila and GLH in a mixed diet.DOI: 0.3329 a.v20i1-2.16850 Progress. Agric. 20(1 & 2): 57 62, 2009

Abstract: Experiments were carried out in the Field Laboratory of Entomology, Bangladesh Agricultural University, Mymensingh, during February to May, 2008 to investigate the population abundance and to determine the efficacy of three botanical oils (Neem, Mahogani, Karanja) and one synthetic insecticide (Admire 200 SL) against Okra Jassid, Amrasca devastans. The Jassid was first noticed in early March just 7 days after germination and attacked the crop seriously. The highest mean number of Jassid leaf-1 (34) was found in April, 2008. In evaluating the effectiveness of the insecticide and botanical oils to control Okra Jassid, three times applications were made at 7 days interval. The Jassid population varied significantly with the application of insecticide and botanicals. Admire 200 SL give the best result among the treatment. Out of three botanicals Karanja repelled 93.33%, where as Mahogoni and Neem repelled 86.66 and 63.33%.The effectivity of botanicals and synthetic insecticides was found in the following order: Admire 200 SL Karajan oil Mahogani oil Neem oil.DOI: 0.3329 a.v21i1-2.16743 Progress.
