“…1, the square-root transformation of the data of Hollingsworth & Hartstack (1972). For the data of Hollingsworth et al (1968), log-log transformation gives a regression coefficient of +0-63 ± 008 for H. zea and +0-64 ± 016 for T. ni, compared with the exponents of 0-6 and 0-9 calculated by Hollingsworth et al For the data of Barrett et al, log-log transformation gives a regression coefficient for total catch index of +0-63 ±0-19 compared Hollingsworth et al (1968); O. data from Barrett et al (1972).) with their exponent value of 0-42.…”

“…the relationship is approximately linear. Similar though much less comprehensive studies were done by Hollingsworth et al (1968) and Barrett et al (1972). They used blacklight (UV lamps that emit little visible radiation) sources and compared catches from sources of different outputs with those from a standard source.…”

Analysis of published data on catches of insects in light-traps with a variety of light sources and of different designs showed that all conformed to the previously proposed model describing the functioning of a lighttrap : catch = constant X s/WII, where W = trap illumination and / = background illumination. Light-trap catches in differing cloud conditions and in open and woodland situations also varied as predicted by the model. A table of correction factors for different amounts of cloud cover is provided. The results are discussed in relation to use of light-traps and interpretation of light-trap data.

“…Catches with 100-W lamps were increased by 40% of a night's catch, on the basis of Bowden's (1981Bowden's ( , 1982Bowden's ( , 1984 rule relating light-trap catches to the square root of the output of the lamp. The data of Hollingsworth & Hartstack (1972) and of Barrett et al (1972), which Bowden (1982) also quotes, seem to substantiate the rule when the catch is plotted against the square root of the lamp emission in milliwatts (Table I). Accordingly, nightly catches of female moths, corrected on this basis where relevant, were grouped into TABLE I. Regression analysis of (A) relative catch (Hollingsworth & Hartstack, 1972) and (B) catch index (Barrett et al, 1972) standard weeks for the southern hemisphere (Roome, 1974), and the geometric mean weekly catches from the four traps were plotted on an arithmetic scale.…”

The effect of moonlight on the performance of light traps as sampling tools is wellknown and has been quantified by Bowden (he.…”

Population dynamics of the sugarcane borer, Eldana saccharina Walker (Lepidoptera: Pyralidae), in Natal, South Africa

Infestations of the sugarcane pest Eldana saccharina Walker have been consistently serious in one part of the cane-growing belt of Natal, South Africa. Mortality in this region over seven years was estimated from moth catches in light traps, checked against population change measured from extensive larval counts, and plotted against climatic indices. The object was to construct a predictive model to illustrate mortality in other regions of the cane belt, to which infestations have spread in recent years. The spread southwards along the coast did not seem to have resulted from a decrease in natural mortality, but the spread to higher altitudes appeared to be due to lower mortality associated with warmer and drier years. The phenology of the insect and the effect of the annual harvesting cycle on phenology are discussed.

This study aimed to present the design and field test results of an LED (light emitting diode) lamp for integrated pest management (IPM) and other entomological studies. The light spectrum of the LEDs was tuned to optimize insect attraction and lower energy consumption. An electronic circuit with control software was integrated with the lamp, enabling it to operate in standalone mode, automatically identify night and day, monitor and control the battery charge with energy from a photovoltaic solar panel, protect the battery against over-discharge, and provide feedback about the operating status of the system. Additionally, energy consumption is about five times lower than that of the fluorescent lamp, reducing the battery and solar panel size needed for its energy supply. In the 2017/2018 growing season, the smart LED lamp was installed in a Sonne light trap in an irrigated rice field, and the total number of insects captured was compared with the number collected in a conventional light trap fitted with a traditional 15 W black light fluorescent lamp. Total captures in the Sonne trap were approximately three times greater than in the conventional system.
