Abstract Background This study was conducted to generate baseline information on population dynamics of Fall Army Worm (FAW) in cassava-maize intercrop for management technique. Maize (Zea mays) is Africa’s most staple food crop with pest complex as major constraints to its production. The study was carried out at the Abuja Campus of the University of Port Harcourt, Faculty of Agriculture Teaching and Research Farm. A plot size of 3298 m2 was cleared and ploughed; afterward, thirty six (36) ridges were made for the planting. Three varieties of maize grains (a hybrid Oba Super 98, white and yellow locals) were used for the study. Two cropping patterns (Sole maize and Cassava-Maize.-Intercrop) as main factor with a total of 18 sole and 18 intercrop plots and pheromone trap heights (at 1 m and 1.5 m) as sub-factor were used. The traps were mounted 18 days after planting and insect collection commenced at dawn the following day. FAW data in each trap were collected daily between 06.00 and 07.00 h. Maize cobs, fresh and dry weights, numbers of FAW exit holes, tunnels and tunnel lengths were recorded for both cropping patterns in each maize variety. Data were subjected to two-way analysis of variance. Results The results show higher mean value of FAW count in pheromone trap height placed at 1.5 m, and Oba super 98 maize variety intercropped with cassava had higher FAW count. There were significantly higher (P < 0.05) FAW exit holes in maize with pheromone trap height placed at 1.5 m, and maize-cassava intercrops had higher mean values of FAW exit holes. Number of tunnels and tunnel lengths (cm) due to FAW infestation were higher in maize varieties where pheromone traps were placed at 1.5 m. Conclusion Intercropping maize with cassava may suggest increase in FAW bionomics and the presence of abundant host which might increase a spike in its peak period of infestation. The presence of cassava in maize-cassava cropping pattern encourages feeding and/or oviposition of FAW on maize plant; therefore, an alternative cropping pattern should be encouraged in the region.

Intercropping Pattern

The reduction in agricultural land due to land conversion has encouraged several technological innovations in cultivation systems, including intercropping planting patterns. The study aimed to study various intercropping patterns with several varieties of maize which can increase production. The research was conducted at the Sawah Baru Experimental Station of the IPB University, Darmaga, Bogor, from November 2018 to February 2019 using a split-plot design with three replications. The main plot was the cropping systems, consisting of monoculture, single-row intercropping, double-rows intercropping, and triple-rows intercropping. The subplot was the maize varieties, consisting of Sukmaraga, Bima 19, and BISI 2. Regression and correlation analyses were carried out to determine the relationship between microclimate and productivity. The results showed that the productivity of maize and soybean was affected by the interaction between cropping patterns and varieties. The highest productivity of maize was obtained from the intercropping pattern of double rows of BISI 2 maize (7.33 ton ha-1), while the lowest maize productivity was in the intercropping pattern of a single row of Bima 19 maize (2.93 ton ha-1). The highest productivity of soybean was obtained from the intercropping cropping pattern of a single row of BISI 2 maize. The effect of microclimate on various cropping patterns with productivity in this study was a little. Land equivalent ratios (LER) in all treatments were greater than 1 except for intercropping 1 row of Bima 19 maize, indicating that intercropping can increase land productivity.

Seasonal phenology studies were conducted for the grape berry moth (GBM), Endopiza viteana Clemens, by collecting and evaluating larval populations and by monitoring adults with pheromone traps. Three full generations and at least a partial fourth generation of the GBM occur in Missouri. Field testing established that the GBM pheromone incorporated into rubber septa was quite stable. The following treatments did not change effectiveness of such septa for collecting GBM: (1) aging in the field for 10 weeks, (2) refrigerating for 2 years and (3) fresh. Most moths were caught in traps located around the periphery of the vineyard. GBM population dynamics were asynchronous among locations suggesting monitoring programs should be tailored to specific vineyards when implementing pest management programs.

AbstractIn 2002, two types of light traps were compared against sticky yellow cards for efficiency and selectivity in capturing adult swede midge Contarinia nasturtii (Kieffer) (Diptera: Cecidomyiidae). Incandescent light traps were more efficient at capturing swede midge than were sticky traps. Incandescent light traps were more selective than blacklight traps and required less time for processing of samples and identification of captured midges. Emergence (2003 and 2004) and pheromone (2004) traps were used to assess swede midge population dynamics. Captures from emergence traps indicate up to five overlapping emergence events for swede midge each year. Emergence traps captured swede midge earlier in the season than pheromone traps, but pheromone-trap captures continued later in the season than those in emergence traps. Pheromone traps are small and portable, easy to maintain, and capture significantly more swede midge than emergence traps.

Optimal Cropping

To improve farm incomes in developing countries, the foremost question that the farmer must address himself to is: what cropping pattern best uses the fixed resources in order to get the highest returns? During the last decade, the agricultural economists have shown great interest in applying the tools of linear programming to individual farms. Most of the studies conducted elsewhere have shown that, under existing cropping pattern, farm resources were not being utilized optimally on the small farms.[l, 4]. We conducted a survey in the canal-irrigated areas of the Punjab province of Pakistan1 to investigate into the same problem. This short note aims at identifying the opti¬mal cropping pattern and to estimate the increase in farm incomes as a result of a switch towards it on the sampled farms.

Cropping Patterns

Corn (Zea mays L.) is a common food and feed product in the community since it is commonly used as rice substitution as food staple. Fertilizer application is required to attain crop high yields. Plants can receive nutrients from synthetic nitrogen fertilizers (NF) during their growth cycle. However, excessive use of NF might harm the environment. Organic chicken manure (CM), on the other hand, can minimize the harmful impact of NF. Chicken manure benefits to improve the soil’s physical, chemical, and biological properties. To boost maize plant growth and productivity, might employ CM and NF. The objective of this study was to determine the effect of NF and CM on corn growth and yield. This research was conducted in Kembang Seri, Central Bengkulu, Indonesia from November 2019 to February 2020 using Randomized Complete Block Design (RCBD) with two factors and three replications. The first factor was NF doses (100, 125, and 150 %), and the second-factor consisted of CM doses (0, 10, and 20 tons/ha). Data were analyzed using ANOVA F-5%. On shoot dry weight of corn cultivated in a double row cropping pattern, there was an interaction between the dose of N and chicken manure. At 0 tons/ha, the optimum N fertilizer dose for chicken manure is 135.96 %, or 407.86 kg urea/ha. At a dose of 20 tons/ha, the optimum N fertilizer dose for chicken manure is 141.22 %, or 423.65 kg urea/ha. In a double row cropping pattern, different nitrogen fertilizer doses had no effect on corn growth and yield. The optimal dose of chicken manure was 16.65 tons/ha for plant height, 17.35 tons/ha for stem diameter, 18.89 tons/ha for leaf greenness, 17.35 tons/ha for cob length, 15.01 tons/ha for cob weight, 18.87 tons/ha for dry seed weight/plant, and 19.74 tons/ha for dry seed weight/plot.

The data includes secondary data on 10-year rainfall from Depati Parbo and Kayu Aro Station and 10-year climatology from Kayu Aro Climatology Station. The calculation method used is the rainfall intensity Average method, Evapotranspiration modification Penman method, Debit danalan DR.FJ Mock method, cropping patterns, and irrigation water needs. Related to the calculation of 6 alternative cropping patterns with different types of plants and different initial planting plans by making comparisons with the existing discharge factor (Q80). Obtained that the cropping pattern is very possible, namely using the cropping pattern PADI-PADI-PALAWIJA. The most efficient and optimal planting pattern is that this cropping system consists of PADI-PADI-ON with large water demand in tertiary plots (NFR tertiary plots) producing 0 - 1,308 ltr / sec/ha with a maximum of 1,308 ltr / ha / February II, while the need for irrigation water in the intake (DR intake) ranges from 0 - 1,615 ltr sec/ha with a maximum of 1,615 ltr / sec/ha in February II. The available debit and debit in the Irrigation Network Planning Mark is very abundant with the mainstay discharge (Q80) for irrigation, the maximum available debit (Q80) can occur in November with 202,207 ltr / sec/ha and the minimum in August with 115,012 ltr / sec / Ha. Based on the results of the discharge and water above, it can be determined about the ratio of water/air equilibrium between discharge and water Q80 and the need for irrigation water requires a large/adequate surplus.

Frankliniella occidentalis  (Pergande) (Thysanoptera: Thripidae) adult male has sternal glands whose role is to produce pheromones. It is known that there are two major components in the headspace volatiles of thrips adult male that are not present in the headspace volatiles of adult female. Those components, (R)-lavandulyl acetate and neryl (S)-2-methylbutanoate were synthesized for the first time in Romania by "Raluca Ripan" Institute for Research in Chemistry (Cluj-Napoca). We have tested a blend of those in the greenhouse cucumber ( Cucumis sativum ) crops of University of Agricultural Sciences and Veterinary Medicine. Period study lasted in 4 weeks. Blue sticky traps were coated with insect glue on both surfaces and a rubber septum which contained the blend was attached in the center of a side of a trap. Two traps with pheromone lure and one trap without pheromone lure were hung up to a 20 cm distance from the tip of the plant. Both female and males were trapped. We observed a higher percentage of males on pheromone trap. Our data revealed that the total number of western flower thrips caught on pheromone traps ranged between 1537 and 1941 as compared with the total number of thrips caught on control trap (1333). According to our results we conclude that pheromone traps could be effective tools for F. occidentalis mass trapping and for the use in integrated pest management strategies.

AbstractIn an outdoor experimental set-up, the number of Prostephanus truncatus (Horn) flying from maize cobs was recorded over 38 observation weeks. Flight activity in the field was recorded for 50 weeks with three pheromone traps, each placed at c. 100–300 m from the first experimental set-up. Multiple regression analyses revealed that both flight initiation and flight activity were partly influenced by mean temperatures, but were not directly related. Flight initiation was mainly dependent on population density. An additional experiment showed that sex ratios among pheromone trap catches were not correlated with the number of beetles caught; sex ratios were female-biased throughout the year. Seasonal fluctuations in flight activity recorded with pheromone traps are mainly dependent on changes in the number and sizes of beetle populations in a given area, as well as on breeding site availability and suitability.
